use tqdm for progressbar

I have created a subclass of joblib.Parallel that uses the ‘tqdm’ package for the progress bar. I find this method more comfortable - the updates are rapid, but uses \r to avoid cluttering the screen. The code I used also finds the number of tasks at the start (if it’s an iterable with len) and uses it.

I want to contribute this code somehow - should I open a PR, or do it in any other way?

Thanks!

this is the same example from your docs.

• first case: a regular iterator. the code does not try to consume it, and only find its length after all work has been dispatched.
• second case: user can add a total_tasks=10 parameter, which allows a progressbar to show from the start.
• third case: if the iterator is already a list, the user doesn’t need to input total_tasks, since the code just uses the list length.

Thank you for your proposal.

I believe that we want to keep joblib without additional dependencies. Unfortunately, this implies that we cannot add a dependency on tqdm.
