PyTorch

Description

pytorch website  

PyTorch is a machine learning library with strong support for neural networks and deep learning. PyTorch also has a large user base and software ecosystem.

Environment Modules

To use PyTorch on HiPerGator, you first need to load one of the PyTorch environment modules. Run module spider pytorch to find out what environment modules are available for PyTorch.

Once you determine which module you want to use, load it as follows (using pytorch/1.7.1 as an example):

module load pytorch/1.7.1

Job Script Examples

To help you get started, here is an example SLURM script for running a PyTorch application on a single GPU on HiPerGator. If you are new to writing SLURM scripts and scheduling SLURM jobs, you will want to first read our help information on using SLURM and writing SLURM scripts. For information about using GPUs on HiPerGator, please see GPU Access.

Note that lines beginning with #SBATCH are instructions to the SLURM scheduler. Lines beginning with # are comments to help you understand the script; feel free to delete them if you adapt this script for your own use.

#!/bin/sh
# The job name: you can choose whatever you want for this.
#SBATCH --job-name=my_pytorch_job

# Your email address and the events for which you want to receive email
# notification (NONE, BEGIN, END, FAIL, ALL).
#SBATCH --mail-user=username@ufl.edu
#SBATCH --mail-type=ALL

# The compute configuration for the job. For a job that uses GPUs, the
# partition must be set to "gpu". This example script requests access
# to a single GPU, 16 CPUs, and 30 GB of RAM for a single PyTorch task.
#SBATCH --nodes=1
#SBATCH --partition=gpu
#SBATCH --ntasks=1
#SBATCH --gpus-per-task=1
#SBATCH --cpus-per-task=16
#SBATCH --mem=30gb

# Specifies how long the job will be allowed to run in HH:MM:SS.
#SBATCH --time=05:05:05

# The log file for all job output. Note the special string "%j", which
# represents the job number.
#SBATCH --output=job_output_%j.out

# Prints the working directory, name of the assigned node, and
# date/time at the top of the output log.
pwd; hostname; date

module load pytorch/1.7.1

# This should be the command you would use if you were running your PyTorch application from the terminal.
