Seems like you are simply out of memory on your GPU.
RuntimeError: CUDA error: out of memory 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.
If you are using the GPU in your workstation which is also driving the displays then it could be that other tasks take up memory causing the training to crash. Check nvidia-smi

I tried to change a variable called self.num_epochs in nnUnetTrainer but i failed ,then i changed the parameter back. but met with this problem, the project could run before i changed the variable
