For example, in your “metuse” environment you should have libnetcdf 4.4.1.1 from conda-forge installed as a dependency of pynio; in your “condaX” environment, you’ll have libnetcdf 4.4.1 from the default channel installed as a dependency of netcdf4. This is just one example of the incompatibilities that can happen when installing from multiple channels. Again, it is important to use “-c conda-forge” on any “conda create …”/“conda install …”/“conda update …” commands you may run for the environment you’re trying to create.</div><div class=""><br class=""></div></div><div class="">Also, I noticed that you chose to install the anaconda package when creating the condaX environment (in step II above). Installing the “anaconda” package is almost guaranteed to make your environment incompatible with most packages from the conda-forge channel (including pynio and pyngl), as described in the previous paragraph. Is there a particular package included in “anaconda” that you need? I would try to list specific packages instead of “anaconda”, and I would try to install them from the conda-forge channel (“-c conda-forge”) if possible.</div><div class=""><br class=""></div><div class="">I hope this helps!</div><div class=""><br class=""></div><div class="">Kevin</div></body></html>
