Forward tqdm constructor arguments to Progress component

[itrushkin]

Description

Progress component with tqdm tracking enabled could not be rendered when no iterable is specified in tqdm initialization.

This PR forwards the total and unit keyword arguments that are used by Progress.tqdm method.

Example code

import gradio as gr
from tqdm import tqdm
import time

def test(s, _=gr.Progress(track_tqdm=True)):
    a = ''
    with tqdm(total=len(s)) as progress_bar:
        for c in s:
            a = c + a
            progress_bar.update()
            time.sleep(1)
    return a

demo = gr.Interface(test, 'text', 'text')
demo.queue().launch()

Render result

Looks like the default value for unit in tqdm.tqdm is it:

Suggested change

	def init_tqdm(self, iterable=None, desc=None, total=None, unit='steps', *args, **kwargs):
	def init_tqdm(self, iterable=None, desc=None, total=None, unit='it', *args, **kwargs):

To keep the same behavior, I used the default gradio value for unit used in:

gradio/gradio/helpers.py

Line 480 in 06808df

unit: str = "steps",

Should I use tqdm value instead?

[abidlabs]

Hmm good point. @aliabid94 can you review this PR?

[aliabid94]

steps is better, this is what will be displayed in the frontend

Thanks @itrushkin for the nice PR. LGTM and can confirm it solves the original issue. Please see my comment above and in addition, two suggestions:

• Can you please add a test to test/test_blocks to test this change?
• Can you please run the formatter scripts (scripts/format_backend.sh) to format and lint the changes?

Should be good to merge then

Thanks a lot. To track the progress of hyperparameter tuning with optuna, I applied this PR and added tqdm.set_description wrapper in create_tracker function. Is there any possibility that set_description or set_postfix wrapper will also be added in gr.Progress?

[abidlabs]

Hi @itrushkin would you be interested in making the suggested changes?

[abidlabs]

Let us know once you have the test in place @itrushkin

[abidlabs]

I'll go ahead and make the changes above so that we can merge this in
