Hello, I am new to OMPython, and not sure what I am doing wrong. I am trying to run my .mo using OMPython. I ran the bouncing ball example with no issues, however, when I try to run my .mo code it fails to import. The strange thing is my code works fine in openModelica. Do I need to convert it into an FMU or something? I believe it may be an underlying C error, but I am not sure. Note I do call external data sets and python code within the .mo file.

Thank you for the help

My .mo file https://drive.google.com/file/d/1uBki5YChlz17A6or5taMdJ00q6ky7fU9/view?usp=sharing
