Python packages are getting installed as UNKNOWN using pip

Question

I tried to install some packages like pycadf. It's failing with the below error:

Searching for pycadf>=0.4.1

Looks like it gets the package from the pypi, installs it as "UNKNOWN". It doesn't happen with every package. setuptools-5.5.1 is installed in my environment.

Any inputs to solve will be helpful.

I had, what looks like, the same problem. The solution for me was to update setuptools.
