No module named 'graphviz' in Jupyter Notebook

In case if your operation system is Ubuntu I recommend to try command:

sudo apt-get install -y graphviz libgraphviz-dev

As @grrr answered above, here is the code:

conda install -c anaconda python-graphviz

conda install -c anaconda pydot

in Anaconda install

• python-graphviz
• pydot

This will fix your problem
