Our article on Towards Data Science introduces the package and provides background information.

PyTorch Forecasting aims to ease state-of-the-art timeseries forecasting with neural networks for real-world cases and research alike. The goal is to provide a high-level API with maximum flexibility for professionals and reasonable defaults for beginners.
Specifically, the package provides

- A timeseries dataset class which abstracts handling variable transformations, missing values,
randomized subsampling, multiple history lengths, etc.
- A base model class which provides basic training of timeseries models along with logging in TensorBoard
and generic visualizations such as actual vs predictions and dependency plots
- Multiple neural network architectures for timeseries forecasting that have been enhanced
for real-world deployment and come with in-built interpretation capabilities
- Multi-horizon timeseries metrics
- Hyperparameter tuning with optuna

The package is built on pytorch-lightning to allow training on CPUs, single and multiple GPUs out-of-the-box.

Installation

If you are working on windows, you need to first install PyTorch with

pip install torch -f https://download.pytorch.org/whl/torch_stable.html.

Otherwise, you can proceed with

pip install pytorch-forecasting

Alternatively, you can install the package via conda

conda install pytorch-forecasting pytorch -c pytorch>=1.7 -c conda-forge

PyTorch Forecasting is now installed from the conda-forge channel while PyTorch is install from the pytorch channel.

To use the MQF2 loss (multivariate quantile loss), also install
pip install pytorch-forecasting[mqf2]

Available models

The documentation provides a comparison of available models.

- Temporal Fusion Transformers for Interpretable Multi-horizon Time Series Forecasting
which outperforms DeepAR by Amazon by 36-69% in benchmarks
- N-BEATS: Neural basis expansion analysis for interpretable time series forecasting
which has (if used as ensemble) outperformed all other methods including ensembles of traditional statical
methods in the M4 competition. The M4 competition is arguably the most important benchmark for univariate time series forecasting.
- N-HiTS: Neural Hierarchical Interpolation for Time Series Forecasting which supports covariates and has consistently beaten N-BEATS. It is also particularly well-suited for long-horizon forecasting.
- DeepAR: Probabilistic forecasting with autoregressive recurrent networks
which is the one of the most popular forecasting algorithms and is often used as a baseline
- Simple standard networks for baselining: LSTM and GRU networks as well as a MLP on the decoder
- A baseline model that always predicts the latest known value

To implement new models or other custom components, see the How to implement new models tutorial. It covers basic as well as advanced architectures.

Usage example

Networks can be trained with the PyTorch Lightning Trainer on pandas Dataframes which are first converted to a TimeSeriesDataSet.
