Cannot install MinkowskiEngine with provided instructions

[gholste]

I have followed all instructions in INSTALL.md, and the provided command for installing the MinkowskiEngine does not work for me. Specifically, I ran every command exactly except for git submodule update --init --recursive and git submodule update --recursive --remote, which also do not work for me; instead, I ran sed -i "s/url.*/url=https:\/\/github.com\/shwoo93\/MinkowskiEngine.git/g" .gitmodules &&\ git submodule update --init --recursive && git submodule update --recursive following #50.

After running python setup.py install --blas_include_dirs=${CONDA_PREFIX}/include --blas=openblas, I get the following error:

--------------------------------

OSError: CUDA_HOME environment variable is not set. Please set it to your CUDA install root.

These instructions seem incomplete to me. What am I supposed to set CUDA_HOME to? I am on a shared server and do not have sudo access or anything like /usr/local/cuda-11.1, which the MinkowskiEngine installation instructions suggest I should set CUDA_HOME to (https://github.com/shwoo93/MinkowskiEngine/tree/bbc30ef581ea6deb505976b663f5fc2358a83749); for example, the command nvcc is not found, but I can still access GPUs.

Update: If I separately install cuda-nvcc through conda (https://anaconda.org/nvidia/cuda-nvcc), I can see that nvcc --version works. I have tried setting export CUDA_HOME=~/miniconda3/envs/convnextv2/bin/nvcc (the output of which nvcc) and running python setup.py install --blas_include_dirs=${CONDA_PREFIX}/include --blas=openblas, but I still get this error:

I am also on a shared server and similarly fail at git submodule update --init --recursive

Just wanted to add pressure to this issue.
