Expected input batch_size (1024) to match target batch_size (64)

This error occurs when there is a mismatch between the batch size of the input data and the expected batch size by the model. In this case, the input batch size is 1024, but the target batch size is 64.

To fix this error, you need to make sure that the batch size of the input data matches the expected batch size by the model. You can either adjust the batch size of the input data or adjust the model to accept the input batch size.

For example, if you are using a batch size of 1024 for the input data, you can try adjusting it to 64 to match the target batch size. Alternatively, you can modify the model to accept a batch size of 1024 by adjusting the model architecture or using dynamic batching.
