Optimizer.param_group

WebPyTorch optimizers group parameters into sets called groups. Each group can have its own hyper-parameters like learning rates. ... You can access (and even change) these groups, and their hyper-parameters with `optimizer.param_groups`. Most learning rate schedule implementations I've come across do access this and change 'lr'. ### States: WebSep 6, 2024 · optimizer = optim.SGD (filter (lambda p: p.requires_grad, net.parameters ()), lr=0.1) In the snippet above, since the previous optimizer contains all parameters including the fc2 with the changed requires_grad flag. Note that the above snippet assumed a common “train => save => load => freeze parts” scenario.

Parameters: param_group ( dict) – Specifies what Tensors should be optimized along with group specific optimization options. WebParameter: pe_array/enable_scale. This parameter controls whether the IP supports scaling feature values by a per-channel weight. This is used to support batch normalization. In most graphs, the graph compiler ( dla_compiler command) adjusts the convolution weights to account for scale, so this option is usually not required. (Similarly, if a ...
