+
+``tqdm`` derives from the Arabic word *taqaddum* (تقدّم) which can mean "progress,"
+and is an abbreviation for "I love you so much" in Spanish (*te quiero demasiado*).
+
+Instantly make your loops show a smart progress meter - just wrap any
+iterable with ``tqdm(iterable)``, and you're done!
+
+.. code:: python
+
+ from tqdm import tqdm
+ for i in tqdm(range(10000)):
+ ...
+
+``76%|████████████████████████        | 7568/10000 [00:33<00:10, 229.00it/s]``
+
+``trange(N)`` can be also used as a convenient shortcut for
+``tqdm(range(N))``.
+
+|Screenshot|
+ |Video| |Slides| |Merch|
+
+It can also be executed as a module with pipes:
+
+.. code:: sh
+
+ $ seq 9999999 | tqdm --bytes | wc -l
+ 75.2MB [00:00, 217MB/s]
+ 9999999
+
+ $ tar -zcf - docs/ | tqdm --bytes --total `du -sb docs/ | cut -f1` \
+ > backup.tgz
+ 32%|██████████▍ | 8.89G/27.9G [00:42<01:31, 223MB/s]
+
+Overhead is low -- about 60ns per iteration (80ns with ``tqdm.gui``), and is
+unit tested against performance regression.
+By comparison, the well-established
+`ProgressBar <https://github.com/niltonvolpato/python-progressbar>`__ has
+an 800ns/iter overhead.
+
+In addition to its low overhead, ``tqdm`` uses smart algorithms to predict
+the remaining time and to skip unnecessary iteration displays, which allows
+for a negligible overhead in most cases.
+
+``tqdm`` works on any platform
+(Linux, Windows, Mac, FreeBSD, NetBSD, Solaris/SunOS),
+in any console or in a GUI, and is also friendly with IPython/Jupyter notebooks.
+
+``tqdm`` does not require any dependencies (not even ``curses``!), just
+Python and an environment supporting ``carriage return \r`` and
+``line feed \n`` control characters.

+Changelog
+---------
+
+The list of all changes is available either on GitHub's Releases:
+|GitHub-Status|, on the
+`wiki <https://github.com/tqdm/tqdm/wiki/Releases>`__, or on the
+`website <https://tqdm.github.io/releases>`__.
+
+
+Usage
+-----
+
+``tqdm`` is very versatile and can be used in a number of ways.
+The three main ones are given below.
+
+Iterable-based
+~~~~~~~~~~~~~~
+
+Wrap ``tqdm()`` around any iterable:
+
+.. code:: python
+
+ from tqdm import tqdm
+ from time import sleep
+
+ text = ""
+ for char in tqdm(["a", "b", "c", "d"]):
+ sleep(0.25)
+ text = text + char
+
+``trange(i)`` is a special optimised instance of ``tqdm(range(i))``:
+
+.. code:: python
+
+ from tqdm import trange
+
+ for i in trange(100):
+ sleep(0.01)
+
+Instantiation outside of the loop allows for manual control over ``tqdm()``:
+
+.. code:: python
+
+ pbar = tqdm(["a", "b", "c", "d"])
+ for char in pbar:
+ sleep(0.25)
+ pbar.set_description("Processing %s" % char)
+
+Manual
+~~~~~~
+
+Manual control of ``tqdm()`` updates using a ``with`` statement:
+
+.. code:: python
+
+ with tqdm(total=100) as pbar:
+ for i in range(10):
+ sleep(0.1)
+ pbar.update(10)
+
+If the optional variable ``total`` (or an iterable with ``len()``) is
+provided, predictive stats are displayed.
+
+``with`` is also optional (you can just assign ``tqdm()`` to a variable,
+but in this case don't forget to ``del`` or ``close()`` at the end:
+
+.. code:: python
+
+ pbar = tqdm(total=100)
+ for i in range(10):
+ sleep(0.1)
+ pbar.update(10)
+ pbar.close()
+
+Module
+~~~~~~
+
+Perhaps the most wonderful use of ``tqdm`` is in a script or on the command
+line. Simply inserting ``tqdm`` (or ``python -m tqdm``) between pipes will pass
+through all ``stdin`` to ``stdout`` while printing progress to ``stderr``.
+
+The example below demonstrate counting the number of lines in all Python files
+in the current directory, with timing information included.
+
+.. code:: sh
+
+ $ time find . -name '*.py' -type f -exec cat \{} \; | wc -l
+ 857365
+
+ real 0m3.458s
+ user 0m0.274s
+ sys 0m3.325s
+
+ $ time find . -name '*.py' -type f -exec cat \{} \; | tqdm | wc -l
+ 857366it [00:03, 246471.31it/s]
+ 857365
+
+ real 0m3.585s
+ user 0m0.862s
+ sys 0m3.358s
+
+Note that the usual arguments for ``tqdm`` can also be specified.
+
+.. code:: sh
+
+ $ find . -name '*.py' -type f -exec cat \{} \; |
+ tqdm --unit loc --unit_scale --total 857366 >> /dev/null
+ 100%|█████████████████████████████████| 857K/857K [00:04<00:00, 246Kloc/s]
+
+Backing up a large directory?
+
+.. code:: sh
+
+ $ tar -zcf - docs/ | tqdm --bytes --total `du -sb docs/ | cut -f1` \
+ > backup.tgz
+ 44%|██████████████▊ | 153M/352M [00:14<00:18, 11.0MB/s]
+
+This can be beautified further:
+
+.. code:: sh
+
+ $ BYTES="$(du -sb docs/ | cut -f1)"
+ $ tar -cf - docs/ \
+ | tqdm --bytes --total "$BYTES" --desc Processing | gzip \
+ | tqdm --bytes --total "$BYTES" --desc Compressed --position 1 \
+ > ~/backup.tgz
+ Processing: 100%|██████████████████████| 352M/352M [00:14<00:00, 30.2MB/s]
+ Compressed: 42%|█████████▎ | 148M/352M [00:14<00:19, 10.9MB/s]
+
+Or done on a file level using 7-zip:
+
+.. code:: sh
+
+ $ 7z a -bd -r backup.7z docs/ | grep Compressing \
+ | tqdm --total $(find docs/ -type f | wc -l) --unit files \
+ | grep -v Compressing
+ 100%|██████████████████████████▉| 15327/15327 [01:00<00:00, 712.96files/s]
+
+Pre-existing CLI programs already outputting basic progress information will
+benefit from ``tqdm``'s ``--update`` and ``--update_to`` flags:
+
+.. code:: sh
+
+ $ seq 3 0.1 5 | tqdm --total 5 --update_to --null
+ 100%|████████████████████████████████████| 5.0/5 [00:00<00:00, 9673.21it/s]
+ $ seq 10 | tqdm --update --null # 1 + 2 + ... + 10 = 55 iterations
+ 55it [00:00, 90006.52it/s]
+
+FAQ and Known Issues
+--------------------
+
+|GitHub-Issues|
+
+The most common issues relate to excessive output on multiple lines, instead
+of a neat one-line progress bar.
+
+- Consoles in general: require support for carriage return (``CR``, ``\r``).
+- Nested progress bars:
+
+ * Consoles in general: require support for moving cursors up to the
+ previous line. For example,
+ `IDLE <https://github.com/tqdm/tqdm/issues/191#issuecomment-230168030>`__,
+ `ConEmu <https://github.com/tqdm/tqdm/issues/254>`__ and
+ `PyCharm <https://github.com/tqdm/tqdm/issues/203>`__ (also
+ `here <https://github.com/tqdm/tqdm/issues/208>`__,
+ `here <https://github.com/tqdm/tqdm/issues/307>`__, and
+ `here <https://github.com/tqdm/tqdm/issues/454#issuecomment-335416815>`__)
+ lack full support.
+ * Windows: additionally may require the Python module ``colorama``
+ to ensure nested bars stay within their respective lines.
+
+- Unicode:
+
+ * Environments which report that they support unicode will have solid smooth
+ progressbars. The fallback is an ``ascii``-only bar.
+ * Windows consoles often only partially support unicode and thus
+ `often require explicit ascii=True <https://github.com/tqdm/tqdm/issues/454#issuecomment-335416815>`__
+ (also `here <https://github.com/tqdm/tqdm/issues/499>`__). This is due to
+ either normal-width unicode characters being incorrectly displayed as
+ "wide", or some unicode characters not rendering.
+
+- Wrapping generators:
+
+ * Generator wrapper functions tend to hide the length of iterables.
+ ``tqdm`` does not.
+ * Replace ``tqdm(enumerate(...))`` with ``enumerate(tqdm(...))`` or
+ ``tqdm(enumerate(x), total=len(x), ...)``.
+ The same applies to ``numpy.ndenumerate``.
+ * Replace ``tqdm(zip(a, b))`` with ``zip(tqdm(a), b)`` or even
+ ``zip(tqdm(a), tqdm(b))``.
+ * The same applies to ``itertools``.
+ * Some useful convenience functions can be found under ``tqdm.contrib``.
+
+- `Hanging pipes in python2 <https://github.com/tqdm/tqdm/issues/359>`__:
+ when using ``tqdm`` on the CLI, you may need to use Python 3.5+ for correct
+ buffering.
+- `No intermediate output in docker-compose <https://github.com/tqdm/tqdm/issues/771>`__:
+ use ``docker-compose run`` instead of ``docker-compose up`` and ``tty: true``.
+
+If you come across any other difficulties, browse and file |GitHub-Issues|.

+.. code:: python
+
+ class tqdm():
+ """
+ Decorate an iterable object, returning an iterator which acts exactly
+ like the original iterable, but prints a dynamically updating
+ progressbar every time a value is requested.
+ """
+
+ def __init__(self, iterable=None, desc=None, total=None, leave=True,
+ file=None, ncols=None, mininterval=0.1,
+ maxinterval=10.0, miniters=None, ascii=None, disable=False,
+ unit='it', unit_scale=False, dynamic_ncols=False,

+
+Parameters
+~~~~~~~~~~
+
+* iterable : iterable, optional
+ Iterable to decorate with a progressbar.
+ Leave blank to manually manage the updates.
+* desc : str, optional
+ Prefix for the progressbar.
+* total : int or float, optional
+ The number of expected iterations. If unspecified,
+ len(iterable) is used if possible. If float("inf") or as a last
+ resort, only basic progress statistics are displayed
+ (no ETA, no progressbar).
+ If ``gui`` is True and this parameter needs subsequent updating,
+ specify an initial arbitrary large positive number,
+ e.g. 9e9.
+* leave : bool, optional
+ If [default: True], keeps all traces of the progressbar
+ upon termination of iteration.
+ If ``None``, will leave only if ``position`` is ``0``.
+* file : ``io.TextIOWrapper`` or ``io.StringIO``, optional
+ Specifies where to output the progress messages
+ (default: sys.stderr). Uses ``file.write(str)`` and ``file.flush()``
+ methods. For encoding, see ``write_bytes``.
+* ncols : int, optional
+ The width of the entire output message. If specified,
+ dynamically resizes the progressbar to stay within this bound.
+ If unspecified, attempts to use environment width. The
+ fallback is a meter width of 10 and no limit for the counter and
+ statistics. If 0, will not print any meter (only stats).
+* mininterval : float, optional
+ Minimum progress display update interval [default: 0.1] seconds.
+* maxinterval : float, optional
+ Maximum progress display update interval [default: 10] seconds.
+ Automatically adjusts ``miniters`` to correspond to ``mininterval``
+ after long display update lag. Only works if ``dynamic_miniters``
+ or monitor thread is enabled.
+* miniters : int or float, optional
+ Minimum progress display update interval, in iterations.
+ If 0 and ``dynamic_miniters``, will automatically adjust to equal
+ ``mininterval`` (more CPU efficient, good for tight loops).
+ If > 0, will skip display of specified number of iterations.
+ Tweak this and ``mininterval`` to get very efficient loops.
+ If your progress is erratic with both fast and slow iterations
+ (network, skipping items, etc) you should set miniters=1.
+* ascii : bool or str, optional
+ If unspecified or False, use unicode (smooth blocks) to fill
+ the meter. The fallback is to use ASCII characters " 123456789#".
+* disable : bool, optional
+ Whether to disable the entire progressbar wrapper
+ [default: False]. If set to None, disable on non-TTY.
+* unit : str, optional
+ String that will be used to define the unit of each iteration
+ [default: it].
+* unit_scale : bool or int or float, optional
+ If 1 or True, the number of iterations will be reduced/scaled
+ automatically and a metric prefix following the
+ International System of Units standard will be added
+ (kilo, mega, etc.) [default: False]. If any other non-zero
+ number, will scale ``total`` and ``n``.
+* dynamic_ncols : bool, optional
+ If set, constantly alters ``ncols`` and ``nrows`` to the
+ environment (allowing for window resizes) [default: False].
+* smoothing : float, optional
+ Exponential moving average smoothing factor for speed estimates
+ (ignored in GUI mode). Ranges from 0 (average speed) to 1
+ (current/instantaneous speed) [default: 0.3].
+* bar_format : str, optional
+ Specify a custom bar string formatting. May impact performance.
+ [default: '{l_bar}{bar}{r_bar}'], where
+ l_bar='{desc}: {percentage:3.0f}%|' and
+ r_bar='| {n_fmt}/{total_fmt} [{elapsed}<{remaining}, '
+ '{rate_fmt}{postfix}]'
+ Possible vars: l_bar, bar, r_bar, n, n_fmt, total, total_fmt,
+ percentage, elapsed, elapsed_s, ncols, nrows, desc, unit,
+ rate, rate_fmt, rate_noinv, rate_noinv_fmt,
+ rate_inv, rate_inv_fmt, postfix, unit_divisor,
+ remaining, remaining_s, eta.
+ Note that a trailing ": " is automatically removed after {desc}
+ if the latter is empty.
+* initial : int or float, optional
+ The initial counter value. Useful when restarting a progress
+ bar [default: 0]. If using float, consider specifying ``{n:.3f}``
+ or similar in ``bar_format``, or specifying ``unit_scale``.
+* position : int, optional
+ Specify the line offset to print this bar (starting from 0)
+ Automatic if unspecified.
+ Useful to manage multiple bars at once (eg, from threads).
+* postfix : dict or ``*``, optional
+ Specify additional stats to display at the end of the bar.
+ Calls ``set_postfix(**postfix)`` if possible (dict).
+* unit_divisor : float, optional
+ [default: 1000], ignored unless ``unit_scale`` is True.
+* write_bytes : bool, optional
+ If (default: None) and ``file`` is unspecified,
+ bytes will be written in Python 2. If ``True`` will also write
+ bytes. In all other cases will default to unicode.
+* lock_args : tuple, optional
+ Passed to ``refresh`` for intermediate output
+ (initialisation, iterating, and updating).
+* nrows : int, optional
+ The screen height. If specified, hides nested bars outside this
+ bound. If unspecified, attempts to use environment height.
+ The fallback is 20.
+* colour : str, optional
+ Bar colour (e.g. 'green', '#00ff00').
+* delay : float, optional
+ Don't display until [default: 0] seconds have elapsed.
+
+Extra CLI Options
+~~~~~~~~~~~~~~~~~
+
+* delim : chr, optional
+ Delimiting character [default: '\n']. Use '\0' for null.
+ N.B.: on Windows systems, Python converts '\n' to '\r\n'.
+* buf_size : int, optional
+ String buffer size in bytes [default: 256]
+ used when ``delim`` is specified.
+* bytes : bool, optional
+ If true, will count bytes, ignore ``delim``, and default
+ ``unit_scale`` to True, ``unit_divisor`` to 1024, and ``unit`` to 'B'.
+* tee : bool, optional
+ If true, passes ``stdin`` to both ``stderr`` and ``stdout``.
+* update : bool, optional
+ If true, will treat input as newly elapsed iterations,
+ i.e. numbers to pass to ``update()``. Note that this is slow
+ (~2e5 it/s) since every input must be decoded as a number.
+* update_to : bool, optional
+ If true, will treat input as total elapsed iterations,
+ i.e. numbers to assign to ``self.n``. Note that this is slow
+ (~2e5 it/s) since every input must be decoded as a number.
+* null : bool, optional
+ If true, will discard input (no stdout).
+* manpath : str, optional
+ Directory in which to install tqdm man pages.
+* comppath : str, optional
+ Directory in which to place tqdm completion.
+* log : str, optional
+ CRITICAL|FATAL|ERROR|WARN(ING)|[default: 'INFO']|DEBUG|NOTSET.

+
+Description and additional stats
+~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~
+
+Custom information can be displayed and updated dynamically on ``tqdm`` bars
+with the ``desc`` and ``postfix`` arguments:
+
+.. code:: python
+
+ from tqdm import tqdm, trange
+ from random import random, randint
+ from time import sleep
+
+ with trange(10) as t:
+ for i in t:
+ # Description will be displayed on the left
+ t.set_description('GEN %i' % i)
+ # Postfix will be displayed on the right,
+ # formatted automatically based on argument's datatype
+ t.set_postfix(loss=random(), gen=randint(1,999), str='h',
+ lst=[1, 2])
+ sleep(0.1)
+
+ with tqdm(total=10, bar_format="{postfix[0]} {postfix[1][value]:>8.2g}",
+ postfix=["Batch", dict(value=0)]) as t:
+ for i in range(10):
+ sleep(0.1)
+ t.postfix[1]["value"] = i / 2
+ t.update()
+
+Points to remember when using ``{postfix[...]}`` in the ``bar_format`` string:
+
+- ``postfix`` also needs to be passed as an initial argument in a compatible
+ format, and
+- ``postfix`` will be auto-converted to a string if it is a ``dict``-like
+ object. To prevent this behaviour, insert an extra item into the dictionary
+ where the key is not a string.
+
+Additional ``bar_format`` parameters may also be defined by overriding
+``format_dict``, and the bar itself may be modified using ``ascii``:
+
+.. code:: python
+
+ from tqdm import tqdm
+ class TqdmExtraFormat(tqdm):
+ """Provides a `total_time` format parameter"""
+ @property
+ def format_dict(self):
+ d = super(TqdmExtraFormat, self).format_dict
+ total_time = d["elapsed"] * (d["total"] or 0) / max(d["n"], 1)
+ d.update(total_time=self.format_interval(total_time) + " in total")
+ return d
+
+ for i in TqdmExtraFormat(
+ range(9), ascii=" .oO0",
+ bar_format="{total_time}: {percentage:.0f}%|{bar}{r_bar}"):
+ if i == 4:
+ break
+
+.. code::
+
+ 00:00 in total: 44%|0000. | 4/9 [00:00<00:00, 962.93it/s]
+
+Note that ``{bar}`` also supports a format specifier ``[width][type]``.
+
+- ``width``
+
+ * unspecified (default): automatic to fill ``ncols``
+ * ``int >= 0``: fixed width overriding ``ncols`` logic
+ * ``int < 0``: subtract from the automatic default
+
+- ``type``
+
+ * ``a``: ascii (``ascii=True`` override)
+ * ``u``: unicode (``ascii=False`` override)
+ * ``b``: blank (``ascii=" "`` override)
+
+This means a fixed bar with right-justified text may be created by using:
+``bar_format="{l_bar}{bar:10}|{bar:-10b}right-justified"``
+
+Nested progress bars
+~~~~~~~~~~~~~~~~~~~~
+
+``tqdm`` supports nested progress bars. Here's an example:
+
+.. code:: python
+
+ from tqdm.auto import trange
+ from time import sleep
+
+ for i in trange(4, desc='1st loop'):
+ for j in trange(5, desc='2nd loop'):
+ for k in trange(50, desc='3rd loop', leave=False):
+ sleep(0.01)
+
+For manual control over positioning (e.g. for multi-processing use),
+you may specify ``position=n`` where ``n=0`` for the outermost bar,
+``n=1`` for the next, and so on.
+However, it's best to check if ``tqdm`` can work without manual ``position``
+first.
+
+.. code:: python
+
+ from time import sleep
+ from tqdm import trange, tqdm
+ from multiprocessing import Pool, RLock, freeze_support
+
+ L = list(range(9))
+
+ def progresser(n):
+ interval = 0.001 / (n + 2)
+ total = 5000
+ text = "#{}, est. {:<04.2}s".format(n, interval * total)
+ for _ in trange(total, desc=text, position=n):
+ sleep(interval)
+
+ if __name__ == '__main__':
+ freeze_support() # for Windows support
+ tqdm.set_lock(RLock()) # for managing output contention
+ p = Pool(initializer=tqdm.set_lock, initargs=(tqdm.get_lock(),))
+ p.map(progresser, L)
+
+Note that in Python 3, ``tqdm.write`` is thread-safe:
+
+.. code:: python
+
+ from time import sleep
+ from tqdm import tqdm, trange
+ from concurrent.futures import ThreadPoolExecutor
+
+ L = list(range(9))
+
+ def progresser(n):
+ interval = 0.001 / (n + 2)
+ total = 5000
+ text = "#{}, est. {:<04.2}s".format(n, interval * total)
+ for _ in trange(total, desc=text):
+ sleep(interval)
+ if n == 6:
+ tqdm.write("n == 6 completed.")
+ tqdm.write("`tqdm.write()` is thread-safe in py3!")
+
+ if __name__ == '__main__':
+ with ThreadPoolExecutor() as p:
+ p.map(progresser, L)
+
+Hooks and callbacks
+~~~~~~~~~~~~~~~~~~~
+
+``tqdm`` can easily support callbacks/hooks and manual updates.
+Here's an example with ``urllib``:
+
+**``urllib.urlretrieve`` documentation**
+
+ | [...]
+ | If present, the hook function will be called once
+ | on establishment of the network connection and once after each block read
+ | thereafter. The hook will be passed three arguments; a count of blocks
+ | transferred so far, a block size in bytes, and the total size of the file.
+ | [...]
+
+.. code:: python
+
+ import urllib, os
+ from tqdm import tqdm
+ urllib = getattr(urllib, 'request', urllib)
+
+ class TqdmUpTo(tqdm):
+ """Provides `update_to(n)` which uses `tqdm.update(delta_n)`."""
+ def update_to(self, b=1, bsize=1, tsize=None):
+ """
+ b : int, optional
+ Number of blocks transferred so far [default: 1].
+ bsize : int, optional
+ Size of each block (in tqdm units) [default: 1].
+ tsize : int, optional
+ Total size (in tqdm units). If [default: None] remains unchanged.
+ """
+ if tsize is not None:
+ self.total = tsize
+ return self.update(b * bsize - self.n) # also sets self.n = b * bsize
+
+ eg_link = "https://caspersci.uk.to/matryoshka.zip"
+ with TqdmUpTo(unit='B', unit_scale=True, unit_divisor=1024, miniters=1,
+ desc=eg_link.split('/')[-1]) as t: # all optional kwargs
+ urllib.urlretrieve(eg_link, filename=os.devnull,
+ reporthook=t.update_to, data=None)
+ t.total = t.n
+
+Inspired by `twine#242 <https://github.com/pypa/twine/pull/242>`__.
+Functional alternative in
+`examples/tqdm_wget.py <https://github.com/tqdm/tqdm/blob/master/examples/tqdm_wget.py>`__.
+
+It is recommend to use ``miniters=1`` whenever there is potentially
+large differences in iteration speed (e.g. downloading a file over
+a patchy connection).
+
+**Wrapping read/write methods**
+
+To measure throughput through a file-like object's ``read`` or ``write``
+methods, use ``CallbackIOWrapper``:
+
+.. code:: python
+
+ from tqdm.auto import tqdm
+ from tqdm.utils import CallbackIOWrapper
+
+ with tqdm(total=file_obj.size,
+ unit='B', unit_scale=True, unit_divisor=1024) as t:
+ fobj = CallbackIOWrapper(t.update, file_obj, "read")
+ while True:
+ chunk = fobj.read(chunk_size)
+ if not chunk:
+ break
+ t.reset()
+ # ... continue to use `t` for something else
+
+Alternatively, use the even simpler ``wrapattr`` convenience function,
+which would condense both the ``urllib`` and ``CallbackIOWrapper`` examples
+down to:
+
+.. code:: python
+
+ import urllib, os
+ from tqdm import tqdm
+
+ eg_link = "https://caspersci.uk.to/matryoshka.zip"
+ response = getattr(urllib, 'request', urllib).urlopen(eg_link)
+ with tqdm.wrapattr(open(os.devnull, "wb"), "write",
+ miniters=1, desc=eg_link.split('/')[-1],
+ total=getattr(response, 'length', None)) as fout:
+ for chunk in response:
+ fout.write(chunk)
+
+The ``requests`` equivalent is nearly identical:
+
+.. code:: python
+
+ import requests, os
+ from tqdm import tqdm
+
+ eg_link = "https://caspersci.uk.to/matryoshka.zip"
+ response = requests.get(eg_link, stream=True)
+ with tqdm.wrapattr(open(os.devnull, "wb"), "write",
+ miniters=1, desc=eg_link.split('/')[-1],
+ total=int(response.headers.get('content-length', 0))) as fout:
+ for chunk in response.iter_content(chunk_size=4096):
+ fout.write(chunk)
+
+**Custom callback**
+
+``tqdm`` is known for intelligently skipping unnecessary displays. To make a
+custom callback take advantage of this, simply use the return value of
+``update()``. This is set to ``True`` if a ``display()`` was triggered.
+
+.. code:: python
+
+ from tqdm.auto import tqdm as std_tqdm
+
+ def external_callback(*args, **kwargs):
+ ...
+
+ class TqdmExt(std_tqdm):
+ def update(self, n=1):
+ displayed = super(TqdmExt, self).update(n)
+ if displayed:
+ external_callback(**self.format_dict)
+ return displayed
+
+``asyncio``
+~~~~~~~~~~~
+
+Note that ``break`` isn't currently caught by asynchronous iterators.
+This means that ``tqdm`` cannot clean up after itself in this case:
+
+.. code:: python
+
+ from tqdm.asyncio import tqdm
+
+ async for i in tqdm(range(9)):
+ if i == 2:
+ break
+
+Instead, either call ``pbar.close()`` manually or use the context manager syntax:
+
+.. code:: python
+
+ from tqdm.asyncio import tqdm
+
+ with tqdm(range(9)) as pbar:
+ async for i in pbar:
+ if i == 2:
+ break
+
+Pandas Integration
+~~~~~~~~~~~~~~~~~~
+
+Due to popular demand we've added support for ``pandas`` -- here's an example
+for ``DataFrame.progress_apply`` and ``DataFrameGroupBy.progress_apply``:
+
+.. code:: python
+
+ import pandas as pd
+ import numpy as np
+ from tqdm import tqdm
+
+ df = pd.DataFrame(np.random.randint(0, 100, (100000, 6)))
+
+ # Register `pandas.progress_apply` and `pandas.Series.map_apply` with `tqdm`
+ # (can use `tqdm.gui.tqdm`, `tqdm.notebook.tqdm`, optional kwargs, etc.)
+ tqdm.pandas(desc="my bar!")
+
+ # Now you can use `progress_apply` instead of `apply`
+ # and `progress_map` instead of `map`
+ df.progress_apply(lambda x: x**2)
+ # can also groupby:
+ # df.groupby(0).progress_apply(lambda x: x**2)
+
+In case you're interested in how this works (and how to modify it for your
+own callbacks), see the
+`examples <https://github.com/tqdm/tqdm/tree/master/examples>`__
+folder or import the module and run ``help()``.
+
+Keras Integration
+~~~~~~~~~~~~~~~~~
+
+A ``keras`` callback is also available:
+
+.. code:: python
+
+ from tqdm.keras import TqdmCallback
+
+ ...
+
+ model.fit(..., verbose=0, callbacks=[TqdmCallback()])
+
+Dask Integration
+~~~~~~~~~~~~~~~~
+
+A ``dask`` callback is also available:
+
+.. code:: python
+
+ from tqdm.dask import TqdmCallback
+
+ with TqdmCallback(desc="compute"):
+ ...
+ arr.compute()
+
+ # or use callback globally
+ cb = TqdmCallback(desc="global")
+ cb.register()
+ arr.compute()
+
+IPython/Jupyter Integration
+~~~~~~~~~~~~~~~~~~~~~~~~~~~~
+
+IPython/Jupyter is supported via the ``tqdm.notebook`` submodule:
+
+.. code:: python
+
+ from tqdm.notebook import trange, tqdm
+ from time import sleep
+
+ for i in trange(3, desc='1st loop'):
+ for j in tqdm(range(100), desc='2nd loop'):
+ sleep(0.01)
+
+In addition to ``tqdm`` features, the submodule provides a native Jupyter
+widget (compatible with IPython v1-v4 and Jupyter), fully working nested bars
+and colour hints (blue: normal, green: completed, red: error/interrupt,
+light blue: no ETA); as demonstrated below.
+
+|Screenshot-Jupyter1|
+|Screenshot-Jupyter2|
+|Screenshot-Jupyter3|
+
+The ``notebook`` version supports percentage or pixels for overall width
+(e.g.: ``ncols='100%'`` or ``ncols='480px'``).
+
+It is also possible to let ``tqdm`` automatically choose between
+console or notebook versions by using the ``autonotebook`` submodule:
+
+.. code:: python
+
+ from tqdm.autonotebook import tqdm
+ tqdm.pandas()
+
+Note that this will issue a ``TqdmExperimentalWarning`` if run in a notebook
+since it is not meant to be possible to distinguish between ``jupyter notebook``
+and ``jupyter console``. Use ``auto`` instead of ``autonotebook`` to suppress
+this warning.
+
+Note that notebooks will display the bar in the cell where it was created.
+This may be a different cell from the one where it is used.
+If this is not desired, either
+
+- delay the creation of the bar to the cell where it must be displayed, or
+- create the bar with ``display=False``, and in a later cell call
+ ``display(bar.container)``:
+
+.. code:: python
+
+ from tqdm.notebook import tqdm
+ pbar = tqdm(..., display=False)
+
+.. code:: python
+
+ # different cell
+ display(pbar.container)
+
+The ``keras`` callback has a ``display()`` method which can be used likewise:
+
+.. code:: python
+
+ from tqdm.keras import TqdmCallback
+ cbk = TqdmCallback(display=False)
+
+.. code:: python
+
+ # different cell
+ cbk.display()
+ model.fit(..., verbose=0, callbacks=[cbk])
+
+Another possibility is to have a single bar (near the top of the notebook)
+which is constantly re-used (using ``reset()`` rather than ``close()``).
+For this reason, the notebook version (unlike the CLI version) does not
+automatically call ``close()`` upon ``Exception``.
+
+.. code:: python
+
+ from tqdm.notebook import tqdm
+ pbar = tqdm()
+
+.. code:: python
+
+ # different cell
+ iterable = range(100)
+ pbar.reset(total=len(iterable)) # initialise with new `total`
+ for i in iterable:
+ pbar.update()
+ pbar.refresh() # force print final status but don't `close()`
+
+Custom Integration
+~~~~~~~~~~~~~~~~~~
+
+To change the default arguments (such as making ``dynamic_ncols=True``),
+simply use built-in Python magic:
+
+.. code:: python
+
+ from functools import partial
+ from tqdm import tqdm as std_tqdm
+ tqdm = partial(std_tqdm, dynamic_ncols=True)
+
+For further customisation,
+``tqdm`` may be inherited from to create custom callbacks (as with the
+``TqdmUpTo`` example `above <#hooks-and-callbacks>`__) or for custom frontends
+(e.g. GUIs such as notebook or plotting packages). In the latter case:
+
+1. ``def __init__()`` to call ``super().__init__(..., gui=True)`` to disable
+ terminal ``status_printer`` creation.
+2. Redefine: ``close()``, ``clear()``, ``display()``.
+
+Consider overloading ``display()`` to use e.g.
+``self.frontend(**self.format_dict)`` instead of ``self.sp(repr(self))``.
+
+Some submodule examples of inheritance:
+
+- `tqdm/notebook.py <https://github.com/tqdm/tqdm/blob/master/tqdm/notebook.py>`__
+- `tqdm/gui.py <https://github.com/tqdm/tqdm/blob/master/tqdm/gui.py>`__

+
+Dynamic Monitor/Meter
+~~~~~~~~~~~~~~~~~~~~~
+
+You can use a ``tqdm`` as a meter which is not monotonically increasing.
+This could be because ``n`` decreases (e.g. a CPU usage monitor) or ``total``
+changes.
+
+One example would be recursively searching for files. The ``total`` is the
+number of objects found so far, while ``n`` is the number of those objects which
+are files (rather than folders):
+
+.. code:: python
+
+ from tqdm import tqdm
+ import os.path
+
+ def find_files_recursively(path, show_progress=True):
+ files = []
+ # total=1 assumes `path` is a file
+ t = tqdm(total=1, unit="file", disable=not show_progress)
+ if not os.path.exists(path):
+ raise IOError("Cannot find:" + path)
+
+ def append_found_file(f):
+ files.append(f)
+ t.update()
+
+ def list_found_dir(path):
+ """returns os.listdir(path) assuming os.path.isdir(path)"""
+ listing = os.listdir(path)
+ # subtract 1 since a "file" we found was actually this directory
+ t.total += len(listing) - 1
+ # fancy way to give info without forcing a refresh
+ t.set_postfix(dir=path[-10:], refresh=False)
+ t.update(0) # may trigger a refresh
+ return listing
+
+ def recursively_search(path):
+ if os.path.isdir(path):
+ for f in list_found_dir(path):
+ recursively_search(os.path.join(path, f))
+ else:
+ append_found_file(path)
+
+ recursively_search(path)
+ t.set_postfix(dir=path)
+ t.close()
+ return files
+
+Using ``update(0)`` is a handy way to let ``tqdm`` decide when to trigger a
+display refresh to avoid console spamming.
+
+Writing messages
+~~~~~~~~~~~~~~~~
+
+This is a work in progress (see
+`#737 <https://github.com/tqdm/tqdm/issues/737>`__).
+
+Since ``tqdm`` uses a simple printing mechanism to display progress bars,
+you should not write any message in the terminal using ``print()`` while
+a progressbar is open.
+
+To write messages in the terminal without any collision with ``tqdm`` bar
+display, a ``.write()`` method is provided:
+
+.. code:: python
+
+ from tqdm.auto import tqdm, trange
+ from time import sleep
+
+ bar = trange(10)
+ for i in bar:
+ # Print using tqdm class method .write()
+ sleep(0.1)
+ if not (i % 3):
+ tqdm.write("Done task %i" % i)
+ # Can also use bar.write()
+
+By default, this will print to standard output ``sys.stdout``. but you can
+specify any file-like object using the ``file`` argument. For example, this
+can be used to redirect the messages writing to a log file or class.
+
+Redirecting writing
+~~~~~~~~~~~~~~~~~~~
+
+If using a library that can print messages to the console, editing the library
+by replacing ``print()`` with ``tqdm.write()`` may not be desirable.
+In that case, redirecting ``sys.stdout`` to ``tqdm.write()`` is an option.
+
+To redirect ``sys.stdout``, create a file-like class that will write
+any input string to ``tqdm.write()``, and supply the arguments
+``file=sys.stdout, dynamic_ncols=True``.
+
+A reusable canonical example is given below:
+
+.. code:: python
+
+ from time import sleep
+ import contextlib
+ import sys
+ from tqdm import tqdm
+ from tqdm.contrib import DummyTqdmFile
+
+
+ @contextlib.contextmanager
+ def std_out_err_redirect_tqdm():
+ orig_out_err = sys.stdout, sys.stderr
+ try:
+ sys.stdout, sys.stderr = map(DummyTqdmFile, orig_out_err)
+ yield orig_out_err[0]
+ # Relay exceptions
+ except Exception as exc:
+ raise exc
+ # Always restore sys.stdout/err if necessary
+ finally:
+ sys.stdout, sys.stderr = orig_out_err
+
+ def some_fun(i):
+ print("Fee, fi, fo,".split()[i])
+
+ # Redirect stdout to tqdm.write() (don't forget the `as save_stdout`)
+ with std_out_err_redirect_tqdm() as orig_stdout:
+ # tqdm needs the original stdout
+ # and dynamic_ncols=True to autodetect console width
+ for i in tqdm(range(3), file=orig_stdout, dynamic_ncols=True):
+ sleep(.5)
+ some_fun(i)
+
+ # After the `with`, printing is restored
+ print("Done!")
+
+Redirecting ``logging``
+~~~~~~~~~~~~~~~~~~~~~~~
+
+Similar to ``sys.stdout``/``sys.stderr`` as detailed above, console ``logging``
+may also be redirected to ``tqdm.write()``.
+
+Warning: if also redirecting ``sys.stdout``/``sys.stderr``, make sure to
+redirect ``logging`` first if needed.
+
+Helper methods are available in ``tqdm.contrib.logging``. For example:
+
+.. code:: python
+
+ import logging
+ from tqdm import trange
+ from tqdm.contrib.logging import logging_redirect_tqdm
+
+ LOG = logging.getLogger(__name__)
+
+ if __name__ == '__main__':
+ logging.basicConfig(level=logging.INFO)
+ with logging_redirect_tqdm():
+ for i in trange(9):
+ if i == 4:
+ LOG.info("console logging redirected to `tqdm.write()`")
+ # logging restored
+
+Monitoring thread, intervals and miniters
+~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~
+
+``tqdm`` implements a few tricks to increase efficiency and reduce overhead.
+
+- Avoid unnecessary frequent bar refreshing: ``mininterval`` defines how long
+ to wait between each refresh. ``tqdm`` always gets updated in the background,
+ but it will display only every ``mininterval``.
+- Reduce number of calls to check system clock/time.
+- ``mininterval`` is more intuitive to configure than ``miniters``.
+ A clever adjustment system ``dynamic_miniters`` will automatically adjust
+ ``miniters`` to the amount of iterations that fit into time ``mininterval``.
+ Essentially, ``tqdm`` will check if it's time to print without actually
+ checking time. This behaviour can be still be bypassed by manually setting
+ ``miniters``.
+
+However, consider a case with a combination of fast and slow iterations.
+After a few fast iterations, ``dynamic_miniters`` will set ``miniters`` to a
+large number. When iteration rate subsequently slows, ``miniters`` will
+remain large and thus reduce display update frequency. To address this:
+
+- ``maxinterval`` defines the maximum time between display refreshes.
+ A concurrent monitoring thread checks for overdue updates and forces one
+ where necessary.
+
+The monitoring thread should not have a noticeable overhead, and guarantees
+updates at least every 10 seconds by default.
+This value can be directly changed by setting the ``monitor_interval`` of
+any ``tqdm`` instance (i.e. ``t = tqdm.tqdm(...); t.monitor_interval = 2``).
+The monitor thread may be disabled application-wide by setting
+``tqdm.tqdm.monitor_interval = 0`` before instantiation of any ``tqdm`` bar.
