RuntimeError: shape '[64, 1, 4, 4]' is invalid for input of size 15360

This error message indicates that the input tensor has an invalid shape. Specifically, the shape of the tensor is [64, 1, 4, 4], which implies that the tensor has 64 samples, each of which is a 1-channel image with a resolution of 4x4 pixels. However, the total number of elements in the tensor is 15360, which is not consistent with the specified shape.

To resolve this error, you should check the input data and ensure that it has the correct shape and size. You may also need to adjust the parameters of your model to match the input data, or preprocess the data to ensure that it is in the correct format. Additionally, you may need to check if there are any issues with the data loading pipeline or the way the data is being fed into the model.
