"WebbIn this tutorial, we will split a Transformer model across two GPUs and use pipeline parallelism to train the model. The model is exactly the same model used in the Sequence-to-Sequence Modeling with nn.Transformer and TorchText tutorial, but is split into two stages. The largest number of parameters belong to the nn.TransformerEncoder layer. " - Sklearn torch

WebbTo eliminate the drawbacks of both Scikit-Learn and PyTorch, a new library named Skorch was created. It let us use PyTorch for creating complicated neural network models and then use Scikit-Learn like API for training and evaluating that model. This frees developers from the burden of writing code for the training and evaluation of models. Webbskorch also provides many convenient features, among others: Learning rate schedulers (Warm restarts, cyclic LR and many more) Scoring using sklearn (and custom) scoring …
