RuntimeError CUDA error unknown errorCUDA kernel errors might be asynchronously reported at some other API callso the stacktrace below might be incorrectFor debugging consider passing CUDA_LAUNCH_BLOC

This error message indicates that there was an unknown error with CUDA, which is a parallel computing platform and programming model used for deep learning. The error could have occurred during the execution of a CUDA kernel, which is a function that is executed on the GPU.

To debug this error, you can try setting the environment variable CUDA_LAUNCH_BLOCKING=1 before running your code. This will force CUDA to report errors synchronously, which can help you identify the exact location of the error.

Other possible causes of this error could be an incompatible version of CUDA or incorrect installation of CUDA drivers. You can try updating your CUDA version or reinstalling the drivers to see if this resolves the issue
