Web2 dagen geleden · I have tried the example of the pytorch forecasting DeepAR implementation as described in the doc. There are two ways to create and plot predictions with the model, which give very different results. One is using the model's forward () function and the other the model's predict () function. One way is implemented in the model's … Web20 mei 2024 · torch.argmax only returns a single index.

Webtorch.index_select torch.index_select(input, dim, index, *, out=None) → Tensor Returns a new tensor which indexes the input tensor along dimension dim using the entries in index which is a LongTensor. The returned tensor has the same number of dimensions as the original tensor ( input ).
WebCopy to clipboard. torch.nn.init.dirac_(tensor, groups=1) [source] Fills the {3, 4, 5}-dimensional input Tensor with the Dirac delta function. Preserves the identity of the inputs in Convolutional layers, where as many input channels are preserved as possible. In case of groups>1, each group of channels preserves identity. Web24 apr. 2024 · From the docs: If given, pads the output with the embedding vector at padding_idx (initialized to zeros) whenever it encounters the index.
