WebFeb 3, 2024 · In the work that I’m doing, after the first conv2d () layer, the output is converted to numpy array to do some processing using .detach (). During this process, the new output will be 3 times bigger and then it is converted back to the tensor to be used as a input for the next conv2d () layer. WebMar 20, 2024 · There seems to be several ways to create a copy of a tensor in PyTorch, including y = tensor.new_tensor (x) #a y = x.clone ().detach () #b y = torch.empty_like (x).copy_ (x) #c y = torch.tensor (x) #d b is explicitly preferred over a and d according to a UserWarning I get if I execute either a or d. Why is it preferred? Performance?
