Hi Diogo,
it’s really bad that our first example does not run. Thank you for reporting this.
You mentioned Import ogs.callbacks gives "Import error".
Could you try if the fix of that resolves the problem for you, please? See my last response from 5 minutes ago: Import ogs.callbacks gives "Import error" - #5 by chleh
We’ll try to reproduce the problem. Btw.: What are your PATH, PYTHONPATH, Python version in the virtual environment? Which distribution do you use (anaconda/minicondy/python.org/…)?
Best regards,
Christoph
