tqdm_notebook leave=False Leaves Whitespace Behind

[utkonos]

python 3.6.3

ipykernel (4.6.1)
ipython (6.2.1)
jupyter (1.0.0)
jupyter-client (5.1.0)
jupyter-console (5.2.0)
jupyter-core (4.4.0)
tqdm (4.19.4)

All installed by pip3 on macOS 10.13.1 and Chrome 62.0.3202.94 (Official Build) (64-bit)

I am seeing extra spaces added on redrawing nested progress meters. The inner meters slowly creep farther from the top bar. Here is a quick script that demonstrates the problem:

import tqdm

address_space = set()

for i in tqdm.tqdm_notebook(range(256), desc='First Octet'):
    for j in tqdm.tqdm_notebook(range(256), desc='Second Octet', leave=False):
        for k in range(256):
            for l in range(256):
                address_space.add('{}.{}.{}.{}'.format(i, j, k, l))

If you substitute the third and fourth nested range(256) with more tqdm, the problem is even more obvious.

I have attached an animated GIF of the problem.

Still on Chrome 100.0.4896.127 on Windows 10. Will this ever get fixed?

After much trial and error this is the only workaround that worked for me in JupyterLab:

from IPython.core.display import HTML

# See https://github.com/bstriner/keras-tqdm/issues/21#issuecomment-443019223
display(HTML("""
    <style>
        .jp-OutputArea-child:has(.jp-OutputArea-prompt:empty) {
              padding: 0 !important;
        }
    </style>
"""))

it does not work on vscode

@gersonjferreira I would open a new issue. The issue that I reported above is fixed (leaving space behind in Jupyter when using the leave parameter).

TqdmCallback for Keras doesn't have this issue.
