I added the function to the tensor class, I still think no new failed tests are introduced by my code, let me know if I should edit something

Hi @lukaM19. The changes look good to me at a first glance. There are a few small changes I have requested above.
I am also noticing the CI tests for test_paddle_tensor_lgamma failing here with the following error:

ret = torch.as_tensor(obj, dtype=dtype, device=device)
E   TypeError: object of type 'Tensor' has no len()

Could you kindly look into this and ensure the relevant CI tests are all passing? Feel free to request a review once this is done. Thanks! 🙂

@YushaArif99 I made some changes and none of the tests associated with my changes and lgamma seem to fail, I would love to know if you think I should change something else
