module 'minisam' has no attribute 'DiagonalLoss'

[Shubham-2302]

I am using PyICP github repo. I built the Sophus from this commit (commit a0fe89a323e20c42d3cecb590937eb7a06b8343a) Reference.
I am using Ubuntu 22 and used virtual environment (venv with python version 3.7.14) to build the PyICP repo, minisam and Sophus repo.

Finally when I run the command python3 main_icp_slam.py it runs in this error.

I am not sure is it caused by Sophus, Eigen, Venv or minisam.

Let me know if anymore information is needed.

Thanks, for any and all the help.

It is probably because you have multiple versions of python on your system and you have installed minisam on another python version. When you run cmake (for installing minisam) look at the version it shows for the python executable and also check your root python version (or environment that you are using).
