Can not call cpu_data on an empty tensor
WebThe at::Tensor class in ATen is not differentiable by default. To add the differentiability of tensors the autograd API provides, you must use tensor factory functions from the torch:: namespace instead of the at:: namespace. For example, while a tensor created with at::ones will not be differentiable, a tensor created with torch::ones will be. WebMar 6, 2024 · デバイス(GPU / CPU)を指定してtorch.Tensorを生成. torch.tensor()やtorch.ones(), torch.zeros()などのtorch.Tensorを生成する関数では、引数deviceを指定できる。 以下のサンプルコードはtorch.tensor()だが、torch.ones()などでも同じ。. 引数deviceにはtorch.deviceのほか、文字列をそのまま指定することもできる。
