 > The recommended way of using Chronos for production use cases is through [AutoGluon](https://auto.gluon.ai), which features ensembling with other statistical and machine learning models for time series forecasting as well as seamless deployments on AWS with SageMaker 🧠. Check out the AutoGluon Chronos [tutorial](https://auto.gluon.ai/stable/tutorials/timeseries/forecasting-chronos.html).
 
-> [!NOTE]  
-> We have added 🧪experimental support for [MLX](https://github.com/ml-explore/mlx) inference. If you have an Apple Silicon Mac, check out the [`mlx`](https://github.com/amazon-science/chronos-forecasting/tree/mlx) branch of this repository for instructions on how to install and use the MLX version of Chronos.

 ### Forecasting
 
 A minimal example showing how to perform forecasting using Chronos models:
 
 ```python
-# for plotting, run: pip install pandas matplotlib
-import matplotlib.pyplot as plt
-import numpy as np
-import pandas as pd
+import pandas as pd  # requires: pip install pandas
 import torch
 from chronos import ChronosPipeline
