To see which software is currently available as a module, type:

module avail
-or-
module av

Too view currently available python modules:

module av python

To search for available gcc modules:

module spider gcc

To load a module so you can use the software, type:

module load {software}/{version}

For example, to load python version 3.10 and confirm its source and version, do:

module load python/3.10
which python
python --version

Or to load the default (often the latest) python module:

module load python
which python
python --version

To load multiple modules, e.g. the default version of cmake, gcc 9.3 and cuda 11.1 and confirm their versions:

module load cmake gcc/9.3 cuda/11.1
cmake --version
gcc --version
nvcc --version

To list currently loaded modules:

module list
-or-
ml

Note that if you use one or more software modules to build another software, then you may need to make sure those same modules are loaded whenever you run that other software.  For example, if you used cuda/11.3 and gcc/9.3 to build pytorch in your python environment, make sure to load cuda/11.3 and gcc/9.3 whenever you want to run pytorch.

To unload a currently loaded module, type:

module unload {software}/{version}
-or-
module unload {software}

For example, to unload a gcc module, do:

module unload gcc

To replace a currently loaded cuda module, say with 12.2, do:

module load cuda/12.2

To purge or unload all currently loaded modules:

module purge
