error: terminated by signal 3221225657

hi

I installed package prophet (not fbprophet) in Python 3.9.4. But fitting a model gives error. With the same data in R code works perfectly. What is the issue?

model = Prophet() model.fit(df1)

Error:

I'm having the same error, no idea what to do with it

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

Hi, are you able to resolve this issue? I am having the same problem too

Hi, was anyone able to resolve this?

I'm still facing this issue even after adding @Karlossal's suggestion.

(On Windows) have tried to change python versions, reinstall cmdstanpy & prophet in new venvs, re-installed Rtools / VS build tools manually... nothing seems to work. The non-descript stacktrace doesn't really help either :(

Intrigued to know if anyone finds the root cause. Thanks! :)

replace cmdstanpy version ,use pip install cmdstanpy==0.9.5 can resolve!!!!

It doesn't, otherwise prophet won't work, you need to upgrade cmdstanpy to its latest version and still I get this mistake 00:51:09 - cmdstanpy - INFO - Chain [1] start processing
