Based on the error message you are trying to call a tensor as a function via:
x = torch.tensor(1.)
x(1)
> TypeError: 'Tensor' object is not callable

but it’s unclear where exactly this is happening based on your code and screenshot.
Could you add a minimal executable code snippet to reproduce the issue?
Also, you can post code snippets by wrapping them into three backticks ```, which makes debugging easier
