+If you are using the old Ubuntu VM (currently installed on EDS 12 computers),
+you also need to set the following environment variables in the terminal in
+order to access the installed gr-cdc module.
+
+```
+$ export PYTHONPATH=/usr/local/lib/python3/dist_packages/
+$ export LD_LIBRARY_PATH=/usr/local/lib/x86_64-linux-gnu/

+set these variables everytime you open a new terminal.
