extent analysis

TL;DR

The error is likely due to a CUDA-related issue, specifically an illegal memory access, which may be caused by a variety of factors including but not limited to GPU memory constraints, incorrect model configuration, or compatibility issues with the CUDA version.

Guidance

  1. Check GPU Memory: Ensure that the GPU has sufficient memory to handle the model and the input data. The error log mentions gpu-memory-utilization=0.9, which might be too high and could lead to memory access issues.
  2. CUDA Version Compatibility: Verify that the CUDA version (12.9) is compatible with the PyTorch version (2.10.0+cu129) and the NVIDIA driver version (570.124.06).
  3. Model Configuration: Review the model configuration, especially the compilation_config and cudagraph_mode, to ensure they are correctly set for the specific use case.
  4. Debugging: Consider passing CUDA_LAUNCH_BLOCKING=1 as suggested in the error log to get more detailed information about the error.

Example

No specific code example can be provided without more context about the model or the exact configuration being used. However, ensuring that the GPU memory utilization is not too high and that all versions of CUDA, PyTorch, and the NVIDIA driver are compatible is crucial.

Notes

  • The issue seems to be related to CUDA and GPU memory access, which can be complex to debug without direct access to the system.
  • The provided stacktrace and error messages suggest a low-level issue that might require adjusting system or model configuration settings.

Recommendation

Apply a workaround by adjusting the gpu-memory-utilization parameter to a lower value (e.g., --gpu-memory-utilization=0.8) to reduce the likelihood of running out of GPU memory, and consider updating or adjusting the CUDA and NVIDIA driver versions to ensure compatibility with PyTorch.
