This release is a pre-release and may not be stable for production use.
Ignite
Ignite is a high-level library to help with training neural networks in PyTorch.
ignite helps you write compact but full-featured training loops in a few lines of code
you get a training loop with metrics, early-stopping, model checkpointing and other features without the boilerplate
Below we show a side-by-side comparison of using pure pytorch and using ignite to create a training loop to train and validate your model with occasional checkpointing:
As you can see, the code is more concise and readable with ignite. Furthermore, adding additional metrics, or things like early stopping is a breeze in ignite, but can start to rapidly increase the complexity of your code when “rolling your own” training loop.
Installation
From pip:
pip install pytorch-igniteFrom conda:
conda install ignite -c pytorchFrom source:
pip install git+https://github.com/pytorch/igniteNightly releases
From pip:
pip install --pre pytorch-igniteFrom conda (this suggests to install pytorch nightly release instead of stable version as dependency):
conda install ignite -c pytorch-nightlyWhy Ignite?
Ignite’s high level of abstraction assumes less about the type of network (or networks) that you are training, and we require the user to define the closure to be run in the training and validation loop. This level of abstraction allows for a great deal more of flexibility, such as co-training multiple models (i.e. GANs) and computing/tracking multiple losses and metrics in your training loop.
Ignite also allows for multiple handlers to be attached to events, and a finer granularity of events in the engine loop.
Documentation
API documentation and an overview of the library can be found here.
Structure
ignite: Core of the library, contains an engine for training and evaluating, all of the classic machine learning metrics and a variety of handlers to ease the pain of training and validation of neural networks!
ignite.contrib: The Contrib directory contains additional modules contributed by Ignite users. Modules vary from TBPTT engine, various optimisation parameter schedulers, logging handlers and a metrics module containing many regression metrics (ignite.contrib.metrics.regression)!
The code in ignite.contrib is not as fully maintained as the core part of the library. It may change or be removed at any time without notice.
Examples
Please check out the examples to see how to use ignite to train various types of networks, as well as how to use visdom or tensorboardX for training visualizations.
