There are two approaches for saving and loading models for inference in PyTorch. Using this approach yields the most intuitive syntax and involves the least amount of code. The disadvantage of this approach is that the serialized data is bound to the specific classes and the exact directory structure used when the model is saved. The reason for this is because pickle does not save the model class itself. Rather, it saves a path to the file containing the class, which is used during load time. Because of this, your code can break in various ways when used in other projects or after refactors. In this recipe, we will explore both ways on how to save and load models for inference. For this recipe, we will use torch and its subsidiaries torch. For sake of example, we will create a neural network for training images. To learn more see the Defining a Neural Network recipe.

If for some reason Optimizer state wasn't saved, pytorch save model, then the saved model state will be useless right? Note Click here to download the full example code. You can resize the terminal window bottom right for a larger view.

Saving and loading multiple models can be helpful for reusing models that you have previously trained. When saving a model comprised of multiple torch. You can also save any other items that may aid you in resuming training by simply appending them to the dictionary. To load the models, first initialize the models and optimizers, then load the dictionary locally using torch. From here, you can easily access the saved items by simply querying the dictionary as you would expect.

Saving and loading DataParallel models. Define and initialize the neural network 3. Failing to do this will yield inconsistent inference results. It is also a safeguard in case the training gets disrupted due to some unforeseen issue. Note Click here to download the full example code. This will download the saved model. Basically, you might want to save everything that you would require to resume training using a checkpoint. Note Click here to download the full example code. Gallery generated by Sphinx-Gallery.
