I have set up miniconda3 python 3.7 with various packages on macOS 10.15.3. For a project, I want to run some Python code from Stata 16.1.
By default, Stata is running the python executable installed by homebrew, @ /usr/local/bin/python3. As I have set up python packages in the miniconda python environment, I have 'set python_exec /usr/local/miniconda3/bin/python3'. Python starts fine and works without any issues.
Starting python from stata with the 'python'-command results in a prompt where basic operation work.
To test the environment a bit better, I try to run 'samplepy.do' from https://www.stata.com/new-in-stata/python-integration/
This fails with the following error message:
Apparently 'from sklearn.svm import SVC' fails from within the Stata python environment. Issuing the command in the interpreter of '/usr/local/miniconda3/bin/python3' run from the command line, does not result in an issue.
Why is the symbol _main not found when run from within the Stata python environment?

Why is the symbol _main not found when run from within the Stata python environment?
