multiple tqdm progress bars when using joblib parallel

问题

I’ve a function:

def func(something):
    for j in tqdm(something):
        ...

which is called by:

joblib.Parallel(n_jobs=4)((joblib.delayed)(s) for s in something_else)

Now, this creates 4 overlapping tqdm progress bars. Is it possible to get 4 separate ones that update independently?

回答1:

EDIT: I was sent this discussion by a friend in which a much cleaner solution is provided. I wrote a quick performance test to make sure that the lock does not cause the threads to block each other. There was no performance hit even when updating bars every millisecond. I recommend that you use that solution instead.
