Install PyTorch on PYNQ

Hello all,

Iā€™d like to share my way how to install PyTorch on PYNQ.
Tested:

  • PYNQ-ZU board
  • PYNQ image 3.0.1

At first, I tried the latest torch==2.0.0 but it caused core dumped every time I imported it. So torch==1.13.1 was selected.

You can install a specific version for your demand:
(1) Go to https://pypi.org/project/torch/#history.
(2) Choose your version of choice, i.e. 1.13.1.
(3) Go to Download files to check if a *_aarch64.whl was released, i.e.
torch-1.13.1-cp310-cp310-manylinux2014_aarch64.whl. Otherwise, you might need to compile it from source.

Note : PYNQ 3.0 uses Python 3.10. You can check the PYNQ Release Notes for each version.

INSTALLATION

  1. Open a new Terminal on Jupyter, or Open a new Terminal over SSH/Serial then su -s to switch to root account.
  2. Activate PYNQ environment
source /etc/profile.d/pynq_venv.sh
  1. Install
pip install --user torch==1.13.1

VERIFICATION
(1) Execute the following Python code snippet to verify the installtion.
(2) If you want to run it on Jupyter, then Kernel -> Restart to restart the IPython kernel.

import torch
x = torch.rand(5, 3)
print(x)
