'RuntimeError: Found dtype Double but expected Float on call to backward
I have the following PyTorch deep learning code in the middle of a training loop:
loss.backward()
loss has the following value:
tensor(434.3251, device='cuda:0', dtype=torch.float64, grad_fn=<MeanBackward0>)
I am getting this error:
File "[,,,]/torch/autograd/__init__.py", line 154, in backward
Variable._execution_engine.run_backward(
RuntimeError: Found dtype Double but expected Float
What am I doing wrong here and how can I fix it? I can provide more context if needed.
Solution 1:[1]
Check your data type of model's weights, input tensor, and label tensor.
There might be a type mismatch and the automatic conversion of the type.
