Fixes errors when trying to use PyTorch 2.0 torch.compile().

In the two fixes I suggested, we addressed the following issue:

torch.split() was expecting a list of integers specifying how to split the tensor along a given dimension. However, it received a list of scalar tensors instead. This mismatch was causing the TorchRuntimeError.

In the first instance, the tensor value_spatial_shapes was passed to the function as a list of scalar tensors, which resulted in the error. By converting them to integers using the .item() method, the error was resolved.

You undid your changes, you will need to make them in the file that mas2former copies from 😅 

Oh bummer!  Thank you for your patience.  I will try to fix it.
