-===== Environment Variables =====
-==== CUDA_HOME, LD_LIBRARY_PATH ====
-Please make sure you specify $CUDA_HOME and if you want to take advantage of CUDNN libraries you will need to append /usr/local/cuda-x.x/lib64 to the $LD_LIBRARY_PATH environment variable.
-For example:
-  cuda_version=9.2
-  export CUDA_HOME=/usr/local/cuda-${cuda_version}
-  export LD_LIBRARY_PATH=$LD_LIBRARY_PATH:$CUDA_HOME/lib64
-Currently we support the same versions of CUDA that the latest version of CUDNN supports. This is not written in stone and we can accommodate most other versions if required; just let techstaff know what your needs are.
-==== CUDA_VISIBLE_DEVICES ====
-Do not set this variable. It will be set for you by SLURM.
-The variable name is actually misleading; since it does NOT mean the amount of devices, but rather the physical device number assigned by the kernel (e.g. /dev/nvidia2).
-For example: If you requested multiple gpu's from SLURM (--gres=gpu:2), the CUDA_VISIBLE_DEVICES variable should contain two numbers(0-3 in this case) separated by a comma (e.g. 1,3).
