Getting Started with DeepSpeed

This guide provides simple steps for preparing a DeepSpeed model to run on Intel® Gaudi® AI accelerator. To set up the environment, refer to the Installation Guide and On-Premise System Update. Make sure to install the DeepSpeed package provided by Intel Gaudi as listed in the Support Matrix.

Note

• Installing public DeepSpeed packages is not supported.

• DeepSpeed is not compatible with lightning-habana 1.6.0.

Start Training a DeepSpeed Model on Gaudi

This example uses the model defined in the cifar10_Deepspeed.py script. It is a simple CNN based model which loads the CIFAR-10 dataset automatically.

1. Run the Intel Gaudi Docker image:

   docker run -it --runtime=habana -e HABANA_VISIBLE_DEVICES=all -e OMPI_MCA_btl_vader_single_copy_mechanism=none --cap-add=sys_nice --net=host --ipc=host vault.habana.ai/gaudi-docker/1.19.0/ubuntu22.04/habanalabs/pytorch-installer-2.5.1:latest
   

2. Install the Intel Gaudi DeepSpeed fork:

   pip install git+https://github.com/HabanaAI/DeepSpeed.git@1.19.0
   

3. Clone the Model References repository inside the container that you have just started:

   git clone https://github.com/HabanaAI/Model-References.git
   

4. Move to the subdirectory containing the cifar_example:

   cd Model-References/PyTorch/examples/DeepSpeed/cifar_example/
   

5. Install the associated requirements:

   pip install -r requirements.txt
   

6. Update PYTHONPATH to include Model-References repository and set PYTHON to Python executable:

   export PYTHONPATH=$PYTHONPATH:Model-References
   export PYTHON=/usr/bin/python3.10
   

   Note

   The Python version depends on the operating system. Refer to the Support Matrix for a full list of supported operating systems and Python versions.

7. Execute the run_ds_habanax8.sh script. If you are running on a single Gaudi, modify the script to set --num_gpus=1.

   deepspeed --num_nodes=1 --num_gpus=8 cifar10_deepspeed.py --deepspeed --deepspeed_config ds_config.json
