Activate an environment

Activate a conda environment using the Package Manager page.

Environment state

The following describes environment states within ArcGIS Pro and their impacts:

• Default—The default ArcGIS Pro conda environment is arcgispro-py3. This environment cannot be modified.
• Active—The conda environment from which the Python interpreter within ArcGIS Pro will initialize. Any package changes (add, update, or remove) are applied to this environment. The active environment is indicated by a green checkmark on the Environment Manager dialog box, and is displayed by name in the Active Environment text box on the Package Manager page.
• Initialized—If Python is started from within ArcGIS Pro, the active environment is initialized for the remainder of the session. Python can be started within ArcGIS Pro by any functionality that uses Python, including but not limited to the Python window, Notebooks or the Geoprocessing pane. This is indicated by a Python Interpeter icon next to the environment name in the Environment Manager dialog box. Other environments can be activated and modified, but the Python interpreter is locked to this environment until ArcGIS Pro is restarted. If a different environment is activated, restart ArcGIS Pro to switch to this environment.
