The models range from classic networks like RNNs to the latest transformers: MLP, LSTM, GRU, RNN, TCN, TimesNet, BiTCN, DeepAR, NBEATS, NBEATSx, NHITS, TiDE, DeepNPTS, TSMixer, TSMixerx, MLPMultivariate, DLinear, NLinear, TFT, Informer, AutoFormer, FedFormer, PatchTST, iTransformer, StemGNN, and TimeLLM.
You can install NeuralForecast with:
pip install neuralforecastor
conda install -c conda-forge neuralforecastVist our Installation Guide for further details.
Minimal Example
from neuralforecast import NeuralForecast
from neuralforecast.models import NBEATS
from neuralforecast.utils import AirPassengersDF
nf = NeuralForecast(
models = [NBEATS(input_size=24, h=12, max_steps=100)],
freq = 'ME'
)
nf.fit(df=AirPassengersDF)
nf.predict()Get Started with this quick guide.
There is a shared belief in Neural forecasting methods' capacity to improve forecasting pipeline's accuracy and efficiency.
Unfortunately, available implementations and published research are yet to realize neural networks' potential. They are hard to use and continuously fail to improve over statistical methods while being computationally prohibitive. For this reason, we created NeuralForecast, a library favoring proven accurate and efficient models focusing on their usability.
- Fast and accurate implementations of more than 30 state-of-the-art models. See the entire collection here.
- Support for exogenous variables and static covariates.
- Interpretability methods for trend, seasonality and exogenous components.
- Probabilistic Forecasting with adapters for quantile losses and parametric distributions.
- Train and Evaluation Losses with scale-dependent, percentage and scale independent errors, and parametric likelihoods.
- Automatic Model Selection with distributed automatic hyperparameter tuning.
- Familiar sklearn syntax:
.fitand.predict.

From 3.3.0 a saved directory holds safetensors weights and JSON metadata, and is loaded without executing any code it contains. Earlier versions used pickle, which runs arbitrary code from the artifact on load, so the legacy format is now opt-in:
nf.save('./checkpoints/') # writes the new format
nf2 = NeuralForecast.load('./checkpoints/') # no pickle, no code executionWhat changed, if you have artifacts or code from an earlier version:
- Older directories need consent or conversion. Pass
allow_pickle=Trueto read one in place, which executes code contained in it, or convert it once withpython -m neuralforecast.migrate ./old_checkpoints/. A directory saved withsave_dataset=Truemust be converted — its dataset has no safe reader. - Remote paths are opt-in.
NeuralForecast.load('s3://bucket/models/', trust_remote=True), because whoever can write that location chooses what runs on the loading machine. - Custom losses, optimizers and schedulers must be registered with
register_loss,register_optimizerorregister_lr_scheduler, in the process that loads as well as the one that saves. TimeLLMcan no longer be saved or loaded. It resolves itsllmargument throughfrom_pretrainedwhile being constructed, so an artifact could direct that fetch. Train and predict with it in the same process.
The save and load guide covers this in full.
