tqdm + pandas + pyqt

[WBP20]

Hi,

I use tqdm with pandas (for geocoding purpose) through :

tqdm.pandas() df['location'] = df['name'].progress_apply(geocode)

It works very well but I would like to see the progress on GUI PyQt app.

If found several clues on how to do it

• Issue #482
• Issue #494
• Issue #696
• https://stackoverflow.com/questions/55050685/how-to-correctly-redirect-stdout-logging-and-tqdm-into-a-pyqt-widget
• https://stackoverflow.com/questions/53381975/display-terminal-output-with-tqdm-in-qplaintextedit

But how can I pass in a custom file and parse out the elapsed time in a write method with tqdm.pandas() ?

thanks in advance.

you'd probably need:

from tqdm import tqdm as tqdm_std

class Qtqdm(tqdm_std):
    # some custom logic here, probably overriding `close`/`clear`/`display`
    # see https://github.com/tqdm/tqdm/#custom-integration
    # and https://github.com/tqdm/tqdm/blob/master/tqdm/notebook.py
    # and https://github.com/tqdm/tqdm/blob/master/tqdm/gui.py
    # or just copy-paste things from https://github.com/tqdm/tqdm/issues/696
    ...

Qtqdm.pandas()
df['location'] = df['name'].progress_apply(geocode)

Hey @casperdcl ,
I've run into the same scenario and found this question. Was there anything more official implemented in tqdm + PyQt in the meantime?

cheers
