AttributeError: module 'folium' has no attribute 'plugins'

[JARND]

Describe the bug
Importing only folium isn't enough to make folium.plugins classes work.

To Reproduce

import folium
import folium.plugins # if we comment this line, the code crash  at line 4: AttributeError: module 'folium' has no attribute 'plugins'

folium.plugins.treelayercontrol.TreeLayerControl

Expected behavior
this 2 lines should compile like this.

import folium
folium.plugins.treelayercontrol.TreeLayerControl

Environment (please complete the following information):
chrome
html
folium: 0.16.1.dev54+g570f293
branca: 0.7.1

Additional context
Maybe it needs another issue, when I do pip install folium it get me the 0.16.0 and I don't have the file:

• https://github.com/python-visualization/folium/blob/main/folium/plugins/treelayercontrol.py
  When I download directly the github it works fine. (this is why my version is 0.16.1.dev54+g570f293 and not 0.16.0)

Possible solutions
https://github.com/python-visualization/folium/blob/main/folium/__init__.py
add the line: import plugins ? (sounds too easy, it feels like a trap XD)

folium is maintained by volunteers. Can you help making a fix for this issue?

• why not, as a folium enthusiast, I would be proud to :)

This is by design. You need to import folium.plugins as stated in our docs. That makes import base folium faster and uncluttered from the multiple plugins in the submodule.
