31.07.2019 · I would recommend to save and load the mode.state_dict(), not the model directly. That being said, I prefer to push the model to CPU first before saving the state_dict. This approach makes sure that I’m able to restore the model on all systems, even when no GPU was found.
Warmstarting model using parameters from a different model in PyTorch¶ Partially loading a model or loading a partial model are common scenarios when transfer learning or training a new complex model. Leveraging trained parameters, even if only a few are usable, ...
03.09.2019 · Hi @Shisho_Sama,. For Tensors in most cases, you should go for clone since this is a PyTorch operation that will be recorded by autograd. >>> t = torch.rand(1, requires_grad=True) >>> t.clone() tensor([0.4847], grad_fn=<CloneBackward>) # <=== as you can see here When it comes to Module, there is no clone method available so you can either use copy.deepcopy or …
Dec 01, 2018 · I have found many correct ways online to copy one pytorch model parameters to another but somehow the copy-paste operation always misses the batch normalization parameters. Everything works fine as long as I only use modules such as conv2d, linear, drop out, max pool etc in my model.
Mar 30, 2017 · The solution mentioned doesn’t work I believe: Copying part of the weights reinforcement-learning. I want to copy a part of the weight from one network to another. Using something like polyak averaging Example: weights_new = k*weights_old + (1-k)*weights_new This is required to implement DDPG.

15.12.2018 · Hi, My question is how to copy the values of trainable parameters from one network to another using the libtorch c++ API. More precisely: I have a custom Network class derived from torch::nn::Module and two instances of this class named n1 and n2. I want to copy the trainable parameters from n2 to n1. In pytorch this can be achieved by …
Sep 03, 2019 · When it comes to Module, there is no clone method available so you can either use copy.deepcopy or create a new instance of the model and just copy the parameters, as proposed in this post Deep copying PyTorch modules.
torch.Tensor.copy_¶ Tensor. copy_ (src, non_blocking = False) → Tensor ¶ Copies the elements from src into self tensor and returns self.. The src tensor must be broadcastable with the self tensor. It may be of a different data type or reside on a different device. Parameters. src – the source tensor to copy from. non_blocking – if True and this copy is between CPU and GPU, the …

06.08.2017 · params1 = model1.named_parameters() params2 = model2.named_parameters() Is there a better way to copy layer parameters from one model to another in 2020 (when trying to transfer a trained encoder or something else)? I created this helper function per the discussion above but it doesn’t seem to be working as expected!
