AttributeError: 'bool' object has no attribute 'requires_grad'

This error occurs when you try to access the `requires_grad` attribute of a boolean value. The `requires_grad` attribute is used in PyTorch to indicate whether a tensor requires gradients to be computed during backpropagation.

To fix this error, check that you are not trying to access the `requires_grad` attribute of a boolean value. It is possible that you have accidentally assigned a boolean value to a tensor that should have had `requires_grad` set to `True`.

Alternatively, you may need to update your code to handle boolean values differently. For example, if you are using a boolean value to control the flow of your program, you may need to use an if-statement or other control structure to handle the boolean value appropriately.
