The anaconda distribution used by the control room workstations is actually installed on the shared drive (/cvs/cds/ligo/apps/anaconda/) for consistency reasons. The version was 4.5.11. I ran the following commands to update it today. Now it is version 4.7.12.
conda update conda
conda update anaconda
The second command takes a while to resolve conflicts, so I've left it running inside a tmux session for now.
Recall that the bash alias for using the anaconda managed python is "apython". I recommend everyone set up a virtual environment when trying out new package installs, to avoid destroying the locking scripts.
