See torch.nn.RNN() and torch.nn.LSTM() for details and workarounds. In some versions of CUDA, RNNs and LSTM networks may have non-deterministic behavior. Which will make other PyTorch operations behave deterministically, too. The latter settingĬontrols only this behavior, unlike e_deterministic_algorithms() You can use this block anywhere that you could write a number. The parameters set the minimum and maximum value that could be generated.
