install the package

[Yike Zhang]

Hello, thanks for the work!

I tried to install the package on windows and linux with the cuda version matched my local installation. But i don't seem to successfully compile the cuda files and I got error

    1 error detected in the compilation of "E:/GitHub/gendr/gendr/cuda/generalized_renderer_cuda_kernel.cu".
    generalized_renderer_cuda_kernel.cu

when i install the package on Windows. I used the command pip install .
I also tried pip install gendr, it does not work as well. Can you provide some help for me to install and try the package?

Thanks!

I cannot speak for support on Windows, as I only operate on linux, but the following document from another CUDA package that I published might help with installation on linux: https://github.com/Felix-Petersen/difflogic/blob/main/INSTALLATION_SUPPORT.md

In the output you provided, it looks like ninja does not exist on your windows installation.

Wrt. linux, it is usually important that the PyTorch CUDA version exactly matches the (sub)version you get from nvcc -v. In some cases, it also works with around 1 subversion of CUDA difference. And one other issue could be that only CUDA but not CUDA Toolkit is installed, e.g., that nvcc is missing.
