RuntimeError: Input type (torch.cuda.LongTensor) and weight type (torch.cuda.FloatTensor) should be the same

This error occurs when you are trying to perform an operation on a tensor and its corresponding weight, but their data types do not match. In this specific case, you are trying to perform an operation on a tensor of type `torch.cuda.LongTensor` and its corresponding weight of type `torch.cuda.FloatTensor`.

To resolve this error, you need to ensure that the data types of the tensor and its weight are the same. You can do this by converting one of them to match the other.

For example, if you want to convert the weight to type `torch.cuda.LongTensor`, you can use the `.long()` method to convert it:

weight = weight.long()

Alternatively, if you want to convert the tensor to type `torch.cuda.FloatTensor`, you can use the `.float()` method to convert it:

tensor = tensor.float()

Once you have converted one of the variables to match the other, you should be able to perform the operation without any issues.
