How to display iteration per second?

[brando90]

e.g. tqdm has it:

 21%|██████████████████████████████████████████████████████████████████▉            21/100 [01:45<04:27,  3.39s/it]

I've actually had a similar question before and added a widget for it: #98

But... I can't find it somehow. I think it got accidently deleted somehow. Perhaps an erroneous merge

I think you are looking for the AdaptiveTransferSpeed: https://progressbar-2.readthedocs.io/en/latest/progressbar.widgets.html#progressbar.widgets.AdaptiveTransferSpeed
Or the FileTransferSpeed: https://progressbar-2.readthedocs.io/en/latest/progressbar.widgets.html#progressbar.widgets.FileTransferSpeed

Instead of using B as the unit parameter, you want it in this case.
Note that by default it uses the si prefixes.

hmm you use using it works?

# progress bar 2 with it per second: https://github.com/WoLpH/python-progressbar/issues/250
import time
import progressbar
with progressbar.ProgressBar(max_value=10, unit='it') as bar:
    for i in range(10):
        time.sleep(0.1)
        time.sleep(1)
        bar.update(i)
100% (10 of 10) |########################| Elapsed Time: 0:00:09 Time:  0:00:09
