Hi there,
I am trying to implement the following procedure:
Set Up ArcGIS with Anaconda: https://medium.com/@ochieng.grace/set-up-arcgis-with-anaconda-94f53c65dbb7
also here: https://my.usgs.gov/confluence/display/EGIS/Using+Anaconda+modules+from+the+ESRI+python+environment
In order to enable Anaconda modules, e.g. Spyder and Jupyter, to work with within an ArcMap 10.3.1 environment.
When I implement the step in the procedure "Create an Anaconda environment for use with ArcGIS," and paste the prompt relevant to ArcMap 10.3.1, I receive the following message from the Anaconda prompt stating that none of the packages can be found:

I'm brand new to conda, so might be missing something obvious. But I can't find anything else online about this specific problem - the websites with procedures don't suggest this should be occurring.
I currently have conda 4.7.12 installed.
Thank you,
