Is Torch And PyTorch Same?

What is Torch FloatTensor?

torch.Tensor is an alias for the default tensor type ( torch.FloatTensor ).

If you have a Tensor data and just want to change its requires_grad flag, use requires_grad_() or detach() to avoid a copy.

If you have a numpy array and want to avoid a copy, use torch.as_tensor() ..

What does Loss backward () do?

When you call loss. backward() , all it does is compute gradient of loss w.r.t all the parameters in loss that have requires_grad = True and store them in parameter. grad attribute for every parameter. pred will have an grad_fn attribute, that references a function that created it, and ties it back to the model.

Does Facebook own PyTorch?
