TensorflowforGPU

Introduction

This page is specifically for people intending to use the TensorFlow package on a GPU-based node, this will also touch on the package Pytorch as well.

Building a Virtual Environment

To build a virtual environment for the GPU nodes you must specify the packages that will run with a GPU.

[pysdlb@login01 ~]$ module load python/anaconda/20220712/3.9
[pysdlb@login01 ~]$ conda create -n tensorflow01
Collecting package metadata (current_repodata.json): done
Solving environment: done

#     $ conda activate tensorflow01

[pysdlb@login01 ~]$ conda activate tensorflow01
(tensorflow01) [pysdlb@login01 ~]$

## Package Plan ##
