unresolved reference Optimizer报错

"Unresolved reference Optimizer" is a common error message that occurs when a variable or function related to an optimizer is not defined or imported correctly in your code. This error often occurs when you are using a deep learning framework like TensorFlow or PyTorch and trying to use an optimizer like Adam or SGD, but have not properly imported or defined it in your code.

To resolve this error, you should check your code for any typos or syntax errors related to the optimizer you are trying to use. Make sure that you have imported the optimizer module correctly and that you are using the correct syntax for the optimizer function. If you are still having trouble, consult the documentation for your deep learning framework to ensure that you are using the optimizer correctly.
