Default Tensorflow module with ROCm 5.6 is not officially supported

Pawsey strongly recommends to migrate Tensorflow slurm job scripts to make use of the new software stack available since March 2025. This because the currently installed GPU driver does not officially supports ROCm 5.6 and the default module (tensorflow/rocm5.6-tf2.12) use this now unsupported version.

The new software stack (March 2025) provides a new tensorflow module (tensorflow/2.13-rocm5.7.3) based on a supported version of ROCm.

To make use of the new software stack please check instructions in the March 2025 Software Update - Important Information
After swapping to the March 2025 software stack, you can proceed to load the new available tensorflow module

This page is still a work in progress and support for Machine Learning workload has just started. Please check it frequently for updates.

Machine Learning workloads are supported on Setonix through a custom TensorFlow container developed by Pawsey. This page illustrates its usage.

On this page:

Introduction

Setonix can support Machine Learning workloads with the use of the large number of AMD GPUs installed on the system. AMD maintains a TensorFlow branch with added support for its GPUs. An official AMD container is also available but, unfortunately, it unusable on Setonix due to its lack of support for both the Cray MPI and some core Python packages. Nevertheless, Pawsey has developed its own TensorFlow container, which can properly run on Setonix. This container is installed on Setonix and available through the module system. The Pawsey TensorFlow container is the only supported way to run TensorFlow on Setonix.

The TensorFlow module

Currently, TensorFlow is available on Setonix via modules that make use of containers:

Terminal 1. Look for the TensorFlow module

$ module avail tensorflow

This because the currently installed GPU driver does not officially supports ROCm 5.6 and the default module (tensorflow/rocm5.6-tf2.12) use this now unsupported version.

The new software stack (March 2025) provides a new tensorflow module (tensorflow/2.13-rocm5.7.3) based on a supported version of ROCm.

So the new officially supported tensorflow module is tensorflow/2.13-rocm5.7.3 and is only accessible after swapping to the new software stack as described in March 2025 Software Update - Important Information:

tensorflow/2.13-rocm5.7.3 (D)

The container is deployed as a module using SHPC (Singularity Registry HPC). SHPC generates a module (listed above) providing convenient aliases for key programs within the container. This means you can run the container's python3 executable without explicitly loading and executing Singularity command. Singularity module is indeed loaded as a dependency when the Tensorflow module is loaded, and all the SIngularity commands are taken care of via wrappers. Here is a very simple example.

Terminal 2. A simple interaction with the TensorFlow module.

$ module load tensorflow/2.13-rocm5.7.3

$ python3
Python 3.10.12 (main, Nov 20 2023, 15:14:05) [GCC 11.4.0] on linux

Note that when requesting the interactive allocation, users should use their correct project name instead of the "yourProjectName" place holder used in the example. Also notice the use of the "-gpu" postfix to the project name in order to be able to access any partition with GPU-nodes. Also note that the resource request for GPU nodes is different from the usual Slurm allocation requests and also the parameters to be given to the srun command. Please refer to the page Example Slurm Batch Scripts for Setonix on GPU Compute Nodes for a detailed explanation of resource allocation on GPU nodes.

Installing additional Python packages

There are at least two ways on which users can install additional Python packages that are required and the container lacks. The first way is to build a user's own container image from the Pawsey Tensorflow container. The second way is the use of a virtual environment saved on Setonix itself, on which the user can install this additional Python packages and be loaded from there. This second way is our recommended procedure.

The trick is to create a virtual environment using the Python installation within the container. This ensures that your Packages are installed considering what is already installed on the container and not on Setonix. However, the virtual environment will be created on the host filesystem, ideally Setonix's /software. Filesystems of Setonix are mounted by default on containers, are writable from within the container, and hence pip can install additional packages. Additionally, virtual environments can be preserved from one container run to the next. We recommend to install this virtual environments in some understandable path under $MYSOFTWARE/manual/software.

To do so, you will need to open a BASH shell within the container. Thanks to the installation of the TensorFlow container as a module, there is no need to explicitly call the singularity command. Instead, the containerised installation provides the bash wrapper that does all the work for the users and then provide an interactive bash session inside the Singularity container. Here is a practical example that installs xarray package into a virtual environment named myenv (it is key to use the --system-site-packages option to preserve the installation of python and packages present in the container):

Terminal 4. Installing additional Python packages using virtual environments

$ module load cpe/24.07
$ module swap pawseyenv/2024.05 pawseyenv/2025.03
$ module load gcc-native/13.2

as you can see, once the environment is active, the modules installed on it area available and loaded without issues. All the modules intalled in the environment are saved on the filesystem in the path created for the environment and can be used in later runs.

Terminal 5. The environment can be used once again.

$ module load cpe/24.07
$ module swap pawseyenv/2024.05 pawseyenv/2025.03
$ module load gcc-native/13.2
$ module load tensorflow/2.13-rocm5.7.3

$ bash

Singularity> source $MYSOFTWARE/manual/software/pythonEnvironments/tensorflowContainer-environments/myenv/bin/activate
(myenv) Singularity>

.

If users consider that there is a Python package that must be included in the Pawsey Tensorflow image, instead of being installed on a host virtual environment (as suggested above), they can submit a ticket to the Help Desk. Pawsey staff can then evaluate the request based on the importance of the package and spread of use in the Machine Learning community.

Users' own containers built on top of Pawsey Tensorflow container

Pawsey TensorFlow container image is publicly distributed on quay.io (external site). We recommend to use a local installation of Docker in your own desktop to build your container on top of Pawsey's TensorFlow image starting your Dockerfile with the line:

FROM quay.io/pawsey/tensorflow:2.13-rocm5.7.3

To pull the image to your local desktop with Docker you can use:

$ docker pull quay.io/pawsey/tensorflow:2.13-rocm5.7.3

To know more about our recommendations of container builds with Docker and later translation into Singularity format for their use in Setonix please refer to the Containers Documentation.

Distributed training

You can run TensorFlow on multiple Setonix nodes. The best way is to submit a job to Slurm using sbatch and a batch script. Let's assume you prepared a Python script implementing your TensorFlow program, and you also have created a virtual environment you want to be active while executing the script. Here is a batch script that implements such a scenario.

Listing 1. runTensorflow.sh : An example batch script to run a TensorFlow distributed training job.

#!/bin/bash --login
#SBATCH --job-name=tensorflow_multiGPU
#SBATCH --partition=gpu
#SBATCH --nodes=2              #2 nodes in this example 
#SBATCH --exclusive            #All resources of the node are exclusive to this job
#                              #8 GPUs per node (16 "allocation packs" in total for the job)
#SBATCH --time=00:05:00
#SBATCH --account=pawsey12345-gpu #IMPORTANT: use your own project and the -gpu suffix

Here, the training distribution takes place on 16 GPUS (8 GPUs per node). Note the use of the TensorFlow environment variables TF_NUM_INTEROP_THREADS and TF_NUM_INTRAOP_THREADS to control the real number of threads to be used by the code (we recommend to leave them as 1). (Note that the resource request for GPU nodes is different from the usual Slurm allocation requests and also the parameters to be given to the srun command. Please refer to the page Example Slurm Batch Scripts for Setonix on GPU Compute Nodes for a detailed explanation of resource allocation on GPU nodes).

Here we use the bash wrapper to call the BASH interpreter within the container to execute a BASH command line which activates the environment and invokes python3 to execute the Python script. For a more complex sequence of commands, it is advised to create a support BASH script to be executed with the bash alias. (If no virtual environment is needed, then sections related to the use of additional packages can be ommited from the script.). Here the name of the python training script is hypothetical example. For detailed examples of Python scripts, please refer to related pages on this topic.
