**📢 BREAKING NEWS**: We released **Chronos**, a suite of pretrained models for zero-shot time series forecasting. Chronos can generate accurate probabilistic predictions for new time series not seen during training. Check it out [here](https://github.com/amazon-science/chronos-forecasting)!

GluonTS is a Python package for probabilistic time series modeling, focusing on deep learning based models,
based on [PyTorch](https://pytorch.org) and [MXNet](https://mxnet.apache.org).


## Installation

GluonTS requires Python 3.7 or newer, and the easiest way to install it is via
`pip`:

```bash
# install with support for torch models
pip install "gluonts[torch]"

# install with support for mxnet models
pip install "gluonts[mxnet]"
```

See the [documentation](https://ts.gluon.ai/stable/getting_started/install.html)
for more info on how GluonTS can be installed.

## Simple Example

To illustrate how to use GluonTS, we train a DeepAR-model and make predictions
using the airpassengers dataset. The dataset consists of a single time
series of monthly passenger numbers between 1949 and 1960. We train the model
on the first nine years and make predictions for the remaining three years.

```py
import pandas as pd
import matplotlib.pyplot as plt

from gluonts.dataset.pandas import PandasDataset
from gluonts.dataset.split import split
from gluonts.torch import DeepAREstimator

# Load data from a CSV file into a PandasDataset
df = pd.read_csv(
    "https://raw.githubusercontent.com/AileenNielsen/"
    "TimeSeriesAnalysisWithPython/master/data/AirPassengers.csv",
    index_col=0,
    parse_dates=True,
)
dataset = PandasDataset(df, target="#Passengers")

# Split the data for training and testing
training_data, test_gen = split(dataset, offset=-36)
test_data = test_gen.generate_instances(prediction_length=12, windows=3)

# Train the model and make predictions
model = DeepAREstimator(
    prediction_length=12, freq="M", trainer_kwargs={"max_epochs": 5}
).train(training_data)

forecasts = list(model.predict(test_data.input))

# Plot predictions
plt.plot(df["1954":], color="black")
for forecast in forecasts:
  forecast.plot()
plt.legend(["True values"], loc="upper left", fontsize="xx-large")
plt.show()
```

Note, the forecasts are displayed in terms of a probability distribution and
the shaded areas represent the 50% and 90% prediction intervals.
