[Mne_analysis] conda upgrade error

[Megan Schendel]

        External Email - Use Caution        

Hi all,
I am attempting to follow upgrade instructions.  I was able to upgrade
conda, and I succeeded in using curl to get the yml file.
However, when I try the conda env update, I eventually get an error when
the update gets to dipy. See below. Any suggestions?

Thanks for your help,
Megan
