Hello everyone, I am unable to run my Pystan / Orbit ML code. I am getting distutils.errors.CompileError: command ‘C:\MinGW\bin\gcc.exe’ failed with exit status 1 error while running my python code.

As mentioned in the group, I have already installed gcc compiler and added distutlis.cfg file. Still I am unable to run Pystan code.  
Python Version: Python 3.6.5 :: Anaconda, Inc.  
OS : Windows 10  
GCC: gcc ([MinGW.org](http://MinGW.org) GCC Build-2) 9.2.0

Here is the detailed error:

Let me know your thoughts.

Sorry this didn’t get answered sooner. And I’m afraid I’m not going to be able to answer. But I can kick it over to the PyStan interface group and let @ariddell know you have a question.

You might also want to try cmdstanpy, which is a more lightweight interface to Stan with less functionality, but an easier install process.

Hi,

There are many things that can go wrong with PyStan + Windows + Anaconda

I recommend following [PyStan on Windows — PyStan 2.19.1.1 documentation](https://pystan2.readthedocs.io/en/latest/windows.html)

There might be a need to add distutils.cfg also in to site-packages/setuptools/\_distutils folder, not sure.

Also use python \< 3.9.
