WebCalling torch.Tensor._values () will return a detached tensor. To track gradients, torch.Tensor.coalesce ().values () must be used instead. Constructing a new sparse COO tensor results a tensor that is not coalesced: >>> s.is_coalesced() False but one can construct a coalesced copy of a sparse COO tensor using the torch.Tensor.coalesce () … WebAt the end of each cycle profiler calls the specified on_trace_ready function and passes itself as an argument. This function is used to process the new trace - either by obtaining the table output or by saving the output on disk as a trace file. To send the signal to the profiler that the next step has started, call prof.step () function.
