Unable to use conda install

[Blair Geng]

Hi,

I'm installing the dependencies on MacOS using Anaconda and having this problem:

When I run the following code,

$ conda install -c conda-forge cython mako matplotlib jupyter pyside pytest mock

I got two solving environment failures and many package conflicts. However, I'm able to do the pip install instead. So I'm wondering if that's fine. Thanks!

Best,

Blair

PS. This is what I have after running conda install:

Collecting package metadata (current_repodata.json): done

Solving environment: failed with initial frozen solve. Retrying with flexible solve.

Solving environment: failed with repodata from current_repodata.json, will retry with next repodata source.

Hi

It seems like the conda failures and conflicts are due to some packages you installed previously.
Anyhow, if pip install works for you and is usable, that is fine. 

Cheers
