Make sure you have conda set up, open up a terminal and create a new conda env from environment.yml by running:
conda env create -f environment.ymlFirst activate the lcls-mockup conda env in a terminal:
conda activate lcls-mockupThen start the Epics server:
python start_epics_server.pyOpen up the epics_pv_test.ipynb notebook after activating the lcls-mockup env, then go through the cells and change them as you like. Good luck!
