Problem with examples on jupyter lab and python 3.9 on anaconda

[manuel josé lazo reyes]

Hi I use anaconda with python 3.9 env and after install for development dapper I execute the example basic_1.py and give me a missing attribute error 'openblas_get_config'
DAPPER-master>python examples/basic_1.py

Maybe I have to install some python module more? Im executing on jupyter lab. Im not expert on python, by the way.
Best regards,
Manuel

Could you try commenting out this line ?

[manuel josé lazo reyes]

Thank you very much. That comment on that line fix the issue. I paste some snapshoot
Now I can also run other examples in jupyter lab. Nice!

[Patrick N. Raanes]

Cool! I'm not sure what the root cause here is (best guess: some form of version incompatibility with your Windows), so the fix is only a workaround. It might cause some things to be a bit slower, but for most purposes it should not matter much.
