environment creation fails for lietorch

[JKBehrens]

Hi,

I tried to install your code, and conda returned this error. I guess I can clone and install lietorch myself, but I wanted to leave this not for you.

Best, Jan

I have the same issue, did you manage to solve?

Hi,

The error here is that your CUDA_HOME environment is not set.

Do which nvcc

if you don't have nvcc, install cudatoolkit with the same version you build pytorch with

then redo which nvcc

Then if the path is for example : /home/usr/anaconda/env_name/bin/nvcc

Do : export CUDA_HOME=/home/usr/anaconda/env_name/ the path without bin/nvcc
