Confluence Retirement

In an effort to consolidate USGS hosted Wikis, myUSGS’ Confluence service is scheduled for retirement on January 27th, 2023. The official USGS Wiki and collaboration space is now SharePoint. Please migrate existing spaces and content to the SharePoint platform and remove it from Confluence at your earliest convenience.

Comment: Added method to "pin" modules to env


Pinning dependencies

Conda does provide a method for pinning dependencies to an environment so you don't have to specify them each time (as: ARCLIST above). You need to list these packages in a filed called pinned in the conda-meta folder. 

Code Block
titleAnaconda command prompt
C:\Users\jwpowell> activate arc1041
(arc1041) C:\Users\jwpowell>(echo python ==2.7.10 & echo numpy ==1.9.2 & echo matplotlib ==1.4.3 & echo scipy ==0.16.0) > %CONDA_PREFIX%\conda-meta\pinned
(arc1041) C:\Users\cprice>type %CONDA_PREFIX%\conda-meta\pinned
python ==2.7.10
numpy ==1.9.2
matplotlib ==1.4.3
scipy ==0.16.0


Now that this has been set up, conda install scipy-0.18.1 will generate an error, and conda install six will update six to the highest version compatible with the pinned modules.

4) Configure ArcGIS python to see Anaconda environment and vice versa
