Could anyone help me?

[fwong90]

have the same problem, let me know if u fix it

[zangyu00544]

I encountered this problem too.

[Karlossal]

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

[fwong90]

I install a new dev enviroment and install all packages again. It works for me 100%

Im using anaconda, in the menu, chose enviroments and create new one, then select it.

hey @fwong90 , I did same task which you listed out, it worked fine for me for the 1st time. But now after next day, when I am trying to run this, it again pops up with same error. After getting that same error, I tried removing an environment in which it was working. And tried same procedure by creating new environment. But now it is not working for me.

Any other solution ???

+1

[federicodecillia]

Same problem here. I tried creating various new virtual environment, then typing pip install prophet but nothing worked

[sscoo]

Same problem

[motdam]

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

[lzxTopC]

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

[Karlossal]

Nope still didn’t resolve the issue

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

[sruap1214]

In my case was weird. It works by installing cmdstanpy==0.9.5. But i got the following error in the process

ERROR: pip's dependency resolver does not currently take into account all the packages that are installed. This behaviour is the source of the following dependency conflicts. prophet 1.1.1 requires cmdstanpy>=1.0.4, but you have cmdstanpy 0.9.5 which is incompatible.

Despite teh preivous error, my code run. Im running python 3.8.15 in a conda environment

[lzxTopC]

yes,i known,but it can do work well,maybe is prophet is not mismatching cmdstanpy.

[oldrios]

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

This works for me, thanks!

[krishnapunyakoti]

has anyone made this work on Mac M1? I am facing tough time making prophet work.

[sjfxking]

Keep only one Python and uninstall the other thoroughly

[sscoo]

has anyone made this work on Mac M1? I am facing tough time making prophet work.

maybe try to run on Google Colab

[cosmofan]

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

This works for me! thank you!

[Bigchicken98]

same problem, prophet==1.1.4，python=3.8，how to fix？

[vivek-kumar007]

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

This works but for every new session I need to run it again and it takes several minutes. How can I avoid running and installing it again and again?
