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. + + +Merch +----- + +You can buy `tqdm branded merch <https://tqdm.github.io/merch>`__ now! + +Contributions +------------- + +|GitHub-Commits| |GitHub-Issues| |GitHub-PRs|
