Hi I am working on Colab with Prophet. In the previous months everything was working properly, but now when I install pystan 2.14 or 2.19 I get an error message.

Basically if I run on Google Colab one of these two pip install

!pip install pystan~=2.14
!pip install pystan~=2.19.1.1

Google Colab returns the following error:

Looking in indexes: https://pypi.org/simple, https://us-python.pkg.dev/colab-wheels/public/simple/

  note: This error originates from a subprocess, and is likely not a problem with pip.

I thought this was the best place where to ask.

Best, Andrea

Hi, pystan 2.x is not supported anymore.

Maybe colab updated python or some other component (compiler?) which has caused this error.

I think latest prophet should support cmdstanpy, maybe try workflow against it.
