• ConfigParser has been renamed to configparser.
• conda install -c conda-forge pykdtree
• conda install -c conda-forge geopy

• conda install -c conda-forge matplotlib
• conda install -c conda-forge cachetools
• conda install -c conda-forge netcdf4
• conda install -c conda-forge basemap

Package installations done. Now I need to upgrade our code for Python 3.6

[htmlboss]
