WARNING: pip is being invoked by an old script wrapper. This will fail in a future version of pip.
Please see https://github.com/pypa/pip/issues/5599 for advice on fixing the underlying issue.
To avoid this problem you can invoke Python with '-m pip' instead of running pip directly.
DEPRECATION: Python 2.7 reached the end of its life on January 1st, 2020. Please upgrade your Python as Python 2.7 is no longer maintained. A future version of pip will drop support for Python 2.7.

Hi Tyler,

We've seen that same situation before, can you check closed issue #1 ?

Let me know if the suggested solutions work for you,

[v-morello]

@tycohen Did you manage to install it or are you still having issues ?

[tycohen]

Yes, just needed to point it to gfortran. Thanks!

[v-morello]

All right then, I am closing this.
