WebNov 12, 2024 · 1 Answer. Your input data is shaped (914, 19), assuming 914 refers to your batch size here, then the in_features corresponds to 19. This can be read as a tensor containing 914 19 -feature-long input vectors. In this case, the in_features of linear1 would be set to 19. Thank you very much.
WebNeural networks can be constructed using the torch.nn package. Now that you had a glimpse of autograd, nn depends on autograd to define models and differentiate them. An nn.Module contains layers, and a method forward (input) that returns the output.
