I assume the example you sent and the context manager know by the end of the loop/or end of context. In addition, a huge benefit of using tqdm instead of a different method for showing a progress bar is that tqdm has little overhead, around 60 nanoseconds per iteration meaning it should not affect performance much, compared to something like ProgressBar, which has an overhead of 800 nanoseconds per iteration. Why don't American traffic signs use pictograms as much as other countries? Follow edited Oct 13 . I will first introduce tqdm, then show an example for machine learning.
