Could you provide the error message you encountered?

Hi,
I have built setup.py but when I tried to run my_train.py it told me ImportError: libcudart.so.10.0: cannot open shared object file: No such file or directory, when I step into this error I found there is no self_cuda_backend in PNSPlusModule.py. I have tried Upgrade environment for NS block.pdf but it doesn't work.
My cuda version is 11.4 which same with pdf's.How can I solves this problem.
Thanks,

Hi,

Thank you for the information.

Are there any error messages during installation?

By the way, my cuda version is 11.4 and my torch version is 1.7.1. I found your pdf suggest torch version is 1.7.0 but it didn't match my cuda version.
Thanks,

When I follow the pdf, I didn't meet any error. I have changed my python version to 3.6.13, modified nvcc_args, modified cxx_args, and when I built setup.py, it told me ''Creating /home/ti-2/.conda/envs/PNS+/lib/python3.6/site-packages/self-cuda.egg-link (link to .)
self-cuda 0.0.0 is already the active version in easy-install.pth
Installed /home/ti-2/Desktop/VPS-main/lib/module/PNS
Processing dependencies for self-cuda==0.0.0
Finished processing dependencies for self-cuda==0.0.0
''
I doubt setup.py doesn't work.

I tried installing it on cuda 11.7 and succeeded.

During installation, I modified CMakeLists.txt and met no error:

If possible, could you provide your whole installation log? Or even better, you could downgrade the cuda version to meet the original requirement.

Hi,
I have solved this problem, I changed cuda version to 11.0 but didn't change setup.py, fortunately it works
thanks for your answers!
