WebDec 9, 2024 · Ordering of elements when using torch.flatten () on 4D arrays. Mole_m7b5 (Daniel Turner) December 9, 2024, 6:14pm #1. I have a 4D tensor of shape [32,64,64,3] which corresponds to [batch, timeframes, frequency_bins, features] and I do tensor.flatten (start_dim=2). I understand the shape will then transform to [32,64,64*3] --> … WebJan 20, 2024 · A tensor can be flattened into a one-dimensional tensor by reshaping it using the method torch.flatten (). This method supports both real and complex-valued input tensors. It takes a torch tensor as its input and returns a torch tensor flattened into one dimension. It takes two optional parameters, start_dim and end_dim.

Examples:: >>> input = torch.randn(32, 1, 5, 5) >>> # With default parameters >>> m = nn.Flatten() >>> output = m(input) >>> … WebLet's create a Python function called flatten(): . def flatten (t): t = t.reshape(1, - 1) t = t.squeeze() return t . The flatten() function takes in a tensor t as an argument.. Since the argument t can be any tensor, we pass -1 as the second argument to the reshape() function. In …

WebJul 17, 2024 · So, in numpy, flatten() always returns a 1-dim array, which is exactly why one would use it. In contrast, in pytorch, it returns a 0-dim tensor for 0-dim tensors, which defeats the whole purpose of flatten: to convert all tensors to 1-dim, so we can handle arbitrarily shaped tensors in a uniform way. In torch: torch.tensor(123).flatten() WebFlatten class torch.nn.Flatten(start_dim=1, end_dim=- 1) [source] Flattens a contiguous range of dims into a tensor. For use with Sequential.
