ArcGIS Notebooks ships with hundreds of open source Python libraries alongside the ArcGIS Python libraries, ArcPy, and the ArcGIS API for Python. The notebook runtime determines which Python libraries come ready to use when you are using ArcGIS Notebooks in ArcGIS Enterprise or ArcGIS Online. With each release, we update the notebook runtimes with new packages and/or updated versions of existing packages. Use the following matrix to find the libraries included with each release of ArcGIS Notebooks.
