The current pystan==2.19.1.1, and it seems that this's the highest version in python 3.9.
I have tried:
- pip install prophet. Using this command I can install the prophet but when running fit I got errors. Error: Unexpected exception formatting exception. Falling back to standard exception.
- pip install fbprophet. couldn't install it.
- conda install -c "conda-forge/label/broken" prophet. Using this command I can install the prophet but when running fit I got errors again. Error: 'StanModel' object has no attribute 'fit_class'.
I have tried everything I can find online so far but still couldn't solve the problem, and unfortunately I can't change my python version cause I need this particular one to install keras and tensorflow in mac M1 system.
