You can install napalm with pip:
pip install napalm
That will install all the core drivers currently available.
Beginning with release 3.0.0 and later, NAPALM offers support for Python 3.6+ only.
OS Package Managers¶
Some execution environments offer napalm through a system-level package manager. Installing with pip outside of a user profile or virtualenv/venv is inadvisable in these cases.
pkg install net-mgmt/py-napalm
This will install napalm and all drivers and dependencies for the default version(s) of python. To install for a specific version, python X.Y, if supported:
pkg install pyXY-napalm
