Python 3.6 Module cannot be found: Folium

Question

I am trying to import folium into a Jupyter notebook I'm working on and I cannot seem to solve the import issues with the Folium library. Has anyone else solved this problem?

!pip install folium
import pandas as pd
import folium

Output from the above yields:

`ModuleNotFoundError                       Traceback (most recent call last)
<ipython-input-7-a9938c267a0c> in <module>()
      1 get_ipython().system('pip install folium')
      2 import pandas as pd
----> 3 import folium

ModuleNotFoundError: No module named 'folium'`

did you install folium first?? – Hankins

Yes. I tried installing outside Jupyter and from within Jupyter. I also tried installing using a conda install. – Katharinekatharsis

just type pip install folium in cmd or terminal – Hankins

I used pip install folium and it works without problem. Then I get the output per my original question above. – Katharinekatharsis

Are you using a virtualenv? – Subgroup

No, just a notebook from the default environment. – Katharinekatharsis

Very strange. If you do import os then os.path, do you get that default environment? – Henshaw

Try pip3 install folium or easy_install folium – Peba

Answer 1

From the source:

• Choose the sandbox folder of your choice (~/sandbox for example)

  $ mkdir visualization
  $ cd visualization
  

• Clone folium from github:

  $ git clone https://github.com/python-visualization/folium
  

• Run the installation script

  $ cd folium
  $ python setup.py install

It is not available via default conda channel. Try using conda-forge channel to install folium as show below:

conda install -c conda-forge folium

Answer 3

I solved the same problem by executing following command

python3 -m pip install folium

Answer 4

I had similar issues as the original problem. I installed successfully from the shell but jupyter would not recognize the module.

What worked for me was (in the jupyter notebook):

!pip install folium

Possible

In modern Jupyter, this is better as %pip install folium. See here about the modern magic install commands that insure installation occurs in the environment backing the kernel underlying the active notebook. – Cabbageworm

Answer 5

My method was:

$ cd C:\programdata\anaconda3\lib\site_packages

Then

git clone https://github.com/python-visualization/folium.git
git clone https://github.com/pallets/jinja.git 

I imported Folium then it worked.

Answer 6

I eventually git-cloned the github repositories for folium and jinja2 into a file and it worked.

Specifically, on my computer, I changed into the right directory from the command line interface with:

$ cd C:\programdata\anaconda3\lib\site_packages

And then typed:

git clone https://github.com/python-visualization/folium.git
git clone https://github.com/pallets/jinja.git

Then import folium (from within python) worked.

I had the same problem while installing with pip3 (macOS with python3).

Manually cloning the github repo solved it.

• Move to the package folder of python 3

  cd /usr/local/lib/python3.6/site-packages/  
  

• Then

  git clone https://github.com/python-visualization/folium  
  cd folium  
  python setup.py install

Answer 8

So for Mac OS with Python 3.x, Anaconda doesn't have the library on its installer by default. You need to clone and manually install 2 two libraries:

1) Navigate to /Users/<username>/anaconda3/lib/python3.6/site-packages

2)Folium

git clone https://github.com/python-visualization/folium.git

cd folium

python setup.py install

3)Branca (This library is a spinoff from folium, that would host the non-map-specific features, if importing folium without branca the kernel complains about missing module named branca)

git clone https://github.com/python-visualization/branca.git

cd branca

python setup.py install

4)Restart your kernel

5)Import

import folium

import branca

Answer 9

Running the following code in the terminal fixed it for me.

$ conda install folium -c conda-forge

Answer 10

Below mentioned command execute in your root working environment.

Solution 1:

conda install folium

Answer 11

Make sure to reinstall jupyter in new conda env. From what I was able to tell, it runs the Jupyter from preexisting environments and that jupyter does not have access to the packages of the new environment

Answer 12

I am using windows 10. I was getting same issue. This is how I fixed it.

Open Command prompt, run as administrator.

type "python" to check if python is installed, if not install python globally.

if python is installed, you will see python prompt, Ctrl+Z to exit and Run :

python -m pip install folium

Answer 13

For osx-64 v0.4.0 the following code worked for me:

Install folium using:

conda install -c conda-forge/label/cf201901 folium

Then verify if the package has been installed

import folium
print('Folium installed and imported!')

Answer 14

Nothing in this thread didn't work for me. So my solution was a little bit strange. I am using a PyCharm, and in my project dir I have a requirements.txt file. PyCharm understands that libraties in this file must be installed, and if they are not, it can install by itself. So I just wrote "folium==0.12.1" in this file and PyCharm done all the work. Maybe another IDE also can do it.
