Install nvcc without root

[zc-alexfan]

❓ Questions & Help

The instruction specifies that we have to make sure nvcc and CUDA paths are correct:

$ PATH=/usr/local/cuda/bin:$PATH
$ echo $PATH
>>> /usr/local/cuda/bin:...

$ CPATH=/usr/local/cuda/include:$CPATH
$ echo $CPATH
>>> /usr/local/cuda/include:...

$ echo $LD_LIBRARY_PATH
>>> /usr/local/cuda/lib64

(I am new to CUDA toolkits) Since I am using a server, I don't have access to root. However, I am able to install PyTorch 1.1 with CUDA Toolkit 9 using Conda. Are those installations shipped with nvcc and CUDA as required by the PyG installation?

If so, where can I find those paths? I tried to echo the above path variables, but none of them contain the folder or bin as shown above.

Thanks in advanced!

Additional information

I tried to skip the paths setup and run pip installs. The installation was complete, but imports are breaking:

Hi, if you have CUDA, you have the nvcc compiler, but to access it from the command line you need to add it to your path. I do not know where CUDA is installed on your system (the default directory is /usr/local), so you should consult your admin.

Problem resolved. The following are solutions to install nvcc without root access in case someone encounters the same problem:

1. Download your runfile according to your OS in here.
2. Run md5sum on your run file to make sure it is not corrupted. The correct checksum is on your CUDA download page. Note, somehow, this file is easily being corrupted. Make sure to check it.
3. Execute the runfile with the --toolkitpath option, where the path is where you would like the toolkit to sit on. Thus, there is no root requirement. --toolkit is to only install CUDA toolkit (no driver). The --override option might not be needed but if there is warning you might want to turn it on.

bash cuda_10.0.130_410.48_linux --silent --override --toolkit --toolkitpath=/scratch/alex/lib/cuda10

4. In your bashrc or zshrc file, specify the three PATHs in PyGeometric installation instruction to the installed location.
5. Remove all previously unsuccessfully installed PyGeometric packages and follow the instruction guide to install it.
