Enhance the progress bar to display customizable message

[2008sliu]

🚀 Feature

• current status: When process_bar is True, tqdm progress bar is displayed with desc="Executing"
• suggested improvements: allow custimizing the message to be some task name

Motivation

When execute_notebook is called in a process pool, many progress bars will be displayed and it is not possible to distinguish which one corresponds to which task.

Possible implement without introducing new parameters

We can just allow the parameter of execute_notebook to be string. If it is non empty string, then display this string before the Executing

if progress_bar:
    from tqdm.auto import tqdm
    desc = 'Executing
    if isinstance(progress_basr, str):
        desc = progress_bar + '|' + desc
    self.pbar = tqdm(total=len(self.nb.cells), unit="cell", desc=desc)

Apologies for the late reply here. End of 2023 was very busy and I wasn't giving papermill much attention.

I believe this PR#778 that just merged solves this now and should enable custom description fields. Please reopen if something there isn't working as intended.
