docker CUDA error

[aiertamundarain]

I have launch a train in neuralangelo docker ang raises the following error

RuntimeError: CUDA error: an illegal memory access was encountered CUDA kernel errors might be asynchronously reported at some other API call, so the stacktrace below might be incorrect. For debugging consider passing CUDA_LAUNCH_BLOCKING=1. Compile with TORCH_USE_CUDA_DSA to enable device-side assertions.

Hi @aiertamundarain, could you post the full error log? Thanks!

It doesn't look like the correct stack trace. Could you share the error log with CUDA_LAUNCH_BLOCKING=1 as suggested from the error message? (It would also be great if it could be formatted as code in the issue/comments!)
