[pyngl-talk] Help with PyNIO installation

Hi Xingang,

Could you please try running “conda install -c conda-forge pyngl pynio” instead of “conda install -c ncar -c khallock pyngl pynio”?

Previously, using the channels “ncar” and “khallock” (with the flags “-c ncar” and “-c khallock”) was the only way to install PyNIO and PyNGL using conda, but we have since uploaded PyNIO, PyNGL, and NCL to the conda-forge channel. 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.
