Profiling your PyTorch Module. PyTorch includes a profiler API that is useful to identify the time and memory costs of various PyTorch operations in your code. Profiler can be easily integrated in your code, and the results can be printed as a table or retured in a JSON trace file. Profiler supports multithreaded models.

Note. torch.nonzero(..., as_tuple=False) (default) returns a 2-D tensor where each row is the index for a nonzero value. torch.nonzero(..., as_tuple=True) returns a tuple of 1-D index tensors, allowing for advanced indexing, so x[x.nonzero(as_tuple=True)] gives all nonzero values of tensor x.Of the returned tuple, each index tensor contains nonzero indices for a certain dimension.

torch.arange¶ torch. arange (start=0, end, step=1, *, out=None, dtype=None, layout=torch.strided, device=None, requires_grad=False) → Tensor ¶ Returns a 1-D tensor of size ⌈ end − start step ⌉ \left\lceil \frac{\text{end} - \text{start}}{\text{step}} \right\rceil ⌈ step end − start ⌉ with values from the interval [start, end) taken with common difference step beginning from start.
