"OSError: CUDA_HOME environment variable is not set." during setup installation

[buemi]

Hi,
I would like to test the DROID-SLAM on my system (Windows 10+Anaconda) but when I launch the following statement:

$ python setup.py install

I receive the following error:

Traceback (most recent call last):
File "C:\SLAM\DROID-SLAM-main\setup.py", line 10, in
CUDAExtension('droid_backends',
File "C:\Anaconda3\envs\droidenv\lib\site-packages\torch\utils\cpp_extension.py", line 912, in CUDAExtension
library_dirs += library_paths(cuda=True)
File "C:\Anaconda3\envs\droidenv\lib\site-packages\torch\utils\cpp_extension.py", line 1027, in library_paths
paths.append(_join_cuda_home(lib_dir))
File "C:\Anaconda3\envs\droidenv\lib\site-packages\torch\utils\cpp_extension.py", line 2035, in join_cuda_home
raise EnvironmentError('CUDA_HOME environment variable is not set. '
OSError: CUDA_HOME environment variable is not set. Please set it to your CUDA install root.

Any idea about how to solve it?

Regards

This should be because your cuda has not configured environment variables, or your cuda has not been successfully installed

The way that I fixed this was by actually installing the CUDA version (11.3) on my Windows machine. I think installing it through conda alone is not enough. For the specific version (11.3), I also needed Visual Studio 2019 installed for the command line tools

@Sebastian-Garcia Did you try to work droid-SLAM on Windows?Did you success it?Could you tell me the key of working it?
CUDA Version? and VC version ?
