I mostly work with R and have very little experience with python. Could you please help me resolve this error? I tried multiple versions of Spladder (3 onwards) and all gave the same error. Your response is greatly appreciated.

Hi.
Excuse me for following up but could you please take a look at this issue?

Dear @ArashDepp ,

Thanks a lot for reaching out. This looks like an issue with your environment, as numba is a just a dependency that SplAdder uses. So the error is not directly related to the SplAdder code. I would recommend to install SplAdder into a clean environment. You could do this by ether using a python venv (more information here https://packaging.python.org/en/latest/guides/installing-using-pip-and-virtual-environments/) or using conda environments (more info here https://docs.conda.io/projects/conda/en/latest/user-guide/tasks/manage-environments.html).

Best,

Andre
