Hi,
I got error when doing training using pytorch lightning.

File "C:\Users\XXX\anaconda3\envs\py310\lib\site-packages\torch\autograd_init_.py", line 197, in backward
Variable._execution_engine.run_backward( # Calls into the C++ engine to run the backward pass
RuntimeError: element 0 of tensors does not require grad and does not have a grad_fn

Please advise,

thanks
