PyTorch profiler can also show the amount of memory (used by the model’s tensors) that was allocated (or released) during the execution of the model’s operators. In the output below, ‘self’ memory corresponds to the memory allocated (released) by the operator, excluding the children calls to the other operators.Your code won't work assuming you are using DDP since you are diverging the models. Model parameters are only initially shared and DDP depends on the gradient synchronization as well as the same parameter update to keep all models equal. In your example you are explicitly updating different parts of the model depending on the rank and will ...May 15, 2022 · In your case, this could look like this: cond = lambda tensor: tensor.gt (value) Then you just need to apply it to each tensor in net.parameters (). To keep it with the same structure, you can do it with dict comprehension: cond_parameters = {n: cond (p) for n,p in net.named_parameters ()} Let's see it in practice!
