Pytorch tensor から numpy ndarray への変換とその逆変換についてまとめる。単純にtorch.from_numpy(x)とx.detach().numpy()を覚えておけばよいので、その使い方を示しておく。 すぐ使いたい場合は以下 numpy to tensor x = torch.from_numpy(x.astype(np.float32)).clone() tensor to numpy x = x.to('cpu').detach().numpy().copy() pytorchでは変数の ...

Sep 13, 2020 · The requires_grad determines whether you would like PyTorch should calculate a gradient with respect to the tensor. This argument is important to set to true if the tensor is part of a model you want to perform back-propagation on, but is not something we will go into deep depth on in this tutorial.
