[pyngl-talk] Help with PyNIO installation

Hi Xingang,

We have found that running PyNIO, PyNGL, and NCL under conda works best if you create an environment to install them in. Installing to the root environment can cause issues like what you’ve described below, especially when using Anaconda, as opposed to Miniconda.

Could you please try creating and activating an environment:
conda create --name <env_name> --channel conda-forge pynio pyngl
source activate <env_name>

Once the environment is activated, you can install any other packages you may need. I would strongly recommend using “--channel conda-forge” on your “conda install …” commands in order to maintain compatibility with Nio and Ngl.

Kevin

However, when I tried to use the same way to update NGL and NIO, the entire anaconda seemed messed up. I tried reinstall, still have the following messages when importing Nio, I don't know what to do:

Conda-forge provides excellent compatibility between packages in order to avoid the dependency issues you experienced, so I would strongly recommend using “-c conda-forge” in your case.
