Based on the below logs it seems you are running into the same issue as discussed in this community article Errors when installing Facebook Prophet.
ERROR: Failed building wheel for fbprophet ERROR: Command errored out with exit status 1:
INFO:pystan:COMPILING THE C++ CODE FOR MODEL anon_model_dfdaf2b8ece8a02eb11f050ec701c0ec NOW. error: command 'gcc' failed with exit status 1
Have you tried the solution mentioned there?
Thank you for the reply.
I tried downgrading the pystan to the version mentioned in the solution. However, I do not know how to install and activate the SCL devtoolset package... I have no idea how to add that line
Care to elaborate on the steps please ?
Thank you once again!
Downgrading the pystan version should be sufficient to fix the issue without using SCL devtoolset. Are you getting the same error? If the error is different please share it. You could also open a support ticket on support.dataiku.com with the new code env diagnostic.
Installing and activating the SCL devtoolset package requires access to the instance where DSS is running. You need to connect by SSH to the instance and run the CLI command. If you don't have access to the instance you need to ask your sysadmin.
