the CI is failing for Distributed examples because something cant find numpy |
Hi, I changed the torch version in requirements.txt file. × No solution found when resolving dependencies: |
- Replace deprecated launch utility with torchrun (see PyTorch docs: https://pytorch.org/docs/stable/distributed.html#launch-utility) - Update README to reflect torchrun usage - Remove main.py (no longer referenced in documentation) - Update CI to test example.py script instead Signed-off-by: jafraustro <[email protected]>

it's failing now with some new errors |
Signed-off-by: jafraustro <[email protected]>
Hello @soumith, The errors occurred because there were not enough GPUs available. To address this, I added a minimum GPU verification step, similar to the approach used in the tensor_parallel_example.py example. This ensures the script only runs when the required number of GPUs are present. |
