 **NOTE** - The [Alternating Least Squares (ALS)](examples/00_quick_start/als_movielens.ipynb) notebooks require a PySpark environment to run. Please follow the steps in the [setup guide](SETUP.md#dependencies-setup) to run these notebooks in a PySpark environment. For the deep learning algorithms, it is recommended to use a GPU machine and to follow the steps in the [setup guide](SETUP.md#dependencies-setup) to set up Nvidia libraries.
