Hi with my trainer I get an error and I am not able to fix it. Log as follows, just when 100% is reached:

torch.cuda.OutOfMemoryError: CUDA out of memory. Tried to allocate 1024.00 MiB (GPU 0; 14.76 GiB total capacity; 11.39 GiB already allocated; 253.88 MiB free; 13.22 GiB reserved in total by PyTorch) If reserved memory is \>\> allocated memory try setting max\_split\_size\_mb to avoid fragmentation. See documentation for Memory Management and PYTORCH\_CUDA\_ALLOC\_CONF

raise subprocess.CalledProcessError(returncode=process.returncode, cmd=cmd)

The problem gets when Generating class images: 100%

How could I fix it? Thanks in advance
