Hello!

I’m attempting to use the ZOS-API in Python (3.8.13). I’ve been running my code from the terminal window and have successfully executed a batch ray trace. I’m working on something that could benefit from using an interactive environment, so I am trying to use a Jupyter notebook or interactive cells in VS code.

When I try to run <import zosapi> the kernel dies immediately. One of the errors thrown is

“Unhandled Exeption: System.IO.FileNotFoundException: Could not load file or assembly ‘ZOSAPI_Interfaces, Version=1.0.0.0, Culture=Neutral, PublicKeyToken=null’ or one of its dependencies. The system cannot find the file specified”

Am I missing a ZOSAPI_Interfaces file? Has anyone encountered this error before?

Thanks,
Jaren

Hi Jaren!

Could you share a snippet of your code so I see how you are loading and defining the API? It sounds like you are using the Python zosapi library instead of the pre-provided boilerplate, but I want to make sure. It would be useful to see everything up to your definition of TheSystem.

Hi Jaren,

Also, are you using Jupyter or JupyterLab?  How did you install Jupyter/JupyterLab?  Did you install both zosapi and jupyter from pip with the same installation of Python or are you using an IDE to install Jupyter/JupyterLab?

Hi pardon me for responding so late, just got a notification that the above comment was chosen as the best answer.

I was just using jupyter, though the same behavior is seen when I use Jupyterlab and ipython notebooks in VS Code. All were installed with the Anaconda navigator, and I pip installed the zosapi in the same conda environment.
