ArcGIS Pro uses conda to manage its Python environments. ArcGIS Pro also comes installed with the pip module for downloading modules from Python Package Index (PyPI). The pip module is used to download Python packages that have not been ported over to conda. PyPI has over 235,000 Python packages available for download, while Anaconda has 633 packages available.
By default, only packages installed using conda are listed in the ArcGIS Pro Python Environment window using the following steps:
To install and view pip packages using the Python Command Prompt, follow these steps:
