TypeError empty received an invalid combination of arguments - got tuple dtype=NoneType device=NoneType but expected one of tuple of ints size tuple of names names torchmemory_format memory_format t

This error message is indicating that the empty() function was called with an invalid combination of arguments. The empty() function creates a new uninitialized tensor with a specified shape and data type.

The function expects either a tuple of integers specifying the shape of the tensor or a tuple of integers specifying the shape along with additional arguments such as data type, device, memory format, etc.

In this case, the function received a tuple, data type, and device as arguments, but this is not a valid combination of arguments. To fix the error, you should pass the correct combination of arguments that the empty() function expects.
