Fix Plan

The fix involves updating the ONNX Runtime to a version that supports the Add node with name '/Add' for BFP16 data type.

Steps to Fix

  • Update onnxruntime to the latest version using pip:

pip install --upgrade onnxruntime

* If the issue persists, try updating `onnx` to the latest version:
  ```bash
pip install --upgrade onnx
  • Modify the test script test_pytorch_onnx_onnxruntime_cuda.py to use a supported data type, such as FP
