I have the same problem

I have the same problem

I also have same problem on windows, but on ubuntu it's working

[chirayu5]

Hey did anyone find a solution to this?

[jia-heng]

I have solved the question 'ERROR: test_opcheck_cpu (main.TestMyAddOut)' by creating a new environment, and upgrading the NVIDIA driver to the newest version, as well as using PyTorch 2.5.0 with CUDA 12.4 and Python 3.12.
but I get a new question:
return self._op(*args, **kwargs) ^^^^^^^^^^^^^^^^^^^^^^^^^ NotImplementedError: Could not run 'extension_cpp::myadd_out' with arguments from the 'CUDA' backend.

@jia-heng I also ran into this issue, and in my case it was due to pytorch not being able to automatically find where cuda is installed. In setup.py you can see that if the variable CUDA_HOME from torch.utils.cpp_extension is None, then cuda is not used. This may happen if your cuda is installed in an unusual location, as in my case. You can work around it by directly setting the environmental variable CUDA_HOME to the location of your cuda install.

For me, I have some problems with the version torch 2.4.0 build from the source, so I decide to upgrade the version by re-installing libtorch and the latest version pytorch 2.5.1. that's solved the problem.
