PyTorch project is a Python package that provides GPU accelerated tensor computation and high level functionalities for building deep learning networks. For licensing details, see the PyTorch license doc on GitHub.
In the sections below, we provide guidance on installing PyTorch on Databricks and give an example of running PyTorch programs. See Integrating Deep Learning Libraries with Apache Spark for an example of integrating a deep learning library with Spark.
This guide is not a comprehensive guide on PyTorch. Refer to the PyTorch website.
PyTorch can be installed as a Databricks library from PyPI. Databricks recommends using version 0.3.0.post4 to install PyTorch to make it available on all cluster nodes. It can be installed by providing the wheel URL from PyTorch previous versions as the PyPI name.
- Python 2: install PyTorch from the URL
- Python 3: install PyTorch from the URL
To test and migrate single-machine PyTorch workflows, you can start with a driver-only cluster on Databricks by setting the number of workers to zero. Though Apache Spark is not functional under this setting, it is a cost-effective way to run single-machine PyTorch workflows.
