Parallel processing with progress bars
copied from cf-staging / parallelbarParallelbar displays the progress of tasks in the process pool for Pool class methods such as map, starmap (since 1.2 version), imap and imap_unordered. Parallelbar is based on the tqdm module and the standard python multiprocessing library. Also, it is possible to handle exceptions that occur within a separate process, as well as set a timeout for the execution of a task by a process.
