Hi all, 

I need to import some external libraries within Cameo. My issue is that I don't know how to import and utilize an external library like yaml in Cameo Systems Modeler. I tried importing the library through the project options as specified in the User Manual: "options" > "project" > "general project options" > "external libraries" and adding a .zip of the library I need. However, whenever I try to run the import within code in a constraint block it throws the error of "ImportError: No module named yaml". 

Any help would be appreciated.
