6ModuleNotFoundError: No module named 'numpy.testing.decorators' while I download catalyst inside the env with "pip install enigma-catalyst matplotlib"

[rubbermen-086]

Dear Catalyst Maintainers,

Before I tell you about my issue, let me describe my environment:

Environment

• Operating System: (Mac OS 10.14.6)
• Python Version: $ python 3.6.13
• Python Bitness: 64'
• How did you install Catalyst: (conda)
• Python packages: $ conda list

Now that you know a little about me, let me tell you about the issue I am
having:

after I have set up the env conda in anaconda3 and used following code:

conda env create -f python3.6-environment.yml
source activate catalyst
pip install enigma-catalyst matplotlib (by troubleshooting)

I can still not properly download catalyst in my env. When I tip this code "pip install enigma-catalyst matplotlib" in terminal, it shows me:
"Building wheel for bcolz (setup.py) ... error......;
Building wheel for cyordereddict (setup.py) ... error.....;
Building wheel for pandas (setup.py) ... error....;
Running setup.py install for pandas ... error......;"

And if I want to check the version of catalyst with code "catalyst --version", it shows me:
"......from numpy.testing.decorators import slow # noqa
ModuleNotFoundError: No module named 'numpy.testing.decorators'"

• What did you expect to happen?

of course I can set up catalyst successfully.

• What happened instead?
  please see above

What steps have you taken to resolve this already?

I have repeated the code "pip install enigma-catalyst matplotlib" in catalyst env, but still doesn't work

Sincerely,
Rubbermen
