I’ve just installed prophet but It’s not working when I try to fit.

I have got mine working.
I installed the cmdstanpy package and imported by using the following…
import cmdstanpy cmdstanpy.install_cmdstan() cmdstanpy.install_cmdstan(compiler=True) # only valid on Windows
I have the same problem. som additional info, i previously ran prophet in a conda environment and didn’t have any issues. I recently changed from using conda envs to virtual envs and a brew python version and now it isn’t working
Same problem here. I tried creating various new virtual environment, then typing
pip install prophetbut nothing workedNope still didn’t resolve the issue
replace cmdstanpy version ,use pip install cmdstanpy==0.9.5 can resolve!!!
