Progress bar for the collect step

What’s the problem this feature will solve?

I run a pip install -r requirements.ini, and it is stuck in this output for over an hour now:

Collecting torch==1.5.0
  Downloading torch-1.5.0-cp36-cp36m-manylinux1_x86_64.whl (752.0 MB)

Though the slowness in downloading the torch library is probably not an issue of pip, I think that a progress bar showing how much time more I could expect to wait.

Describe the solution you’d like

A progress bar in pip output when downloading the libraries

pip does show the download prompt when the terminal it’s being used in is interactive.

In this case, as @eamanu showed, the terminal is not interactive (isatty is False) which disables the progress bar – to pip, it’s the same as if it were dumping output to a text file, since that also looks the same to pip.

Hi,

After make some tests the progress-bar run good into my computer (Debian testing) and into the Dockefile provided by @hershkoy, after attach the docker and run the pip install torch.

I’m not expert on Docker so sorrry for the things that I will write: running docker build it doesn’t provide a tty. So the progress-bar is not show it.

Because pip use progress-bar for show the progress bar, and this how mention @McSinyx will print the progress bar if a tty is connected. But for docker run this seems not to be happen.
