ImportError: Failed to import pydot. You must install pydot and graphviz for `pydotprint` to work.I googled a little then found that I can install pydot with the code pip install pydot. But I know get this error. I am noob in ubuntu and I dont understand what to do. so how do I install pydot ?

python-pydot and graphviz are in the default Ubuntu repositories in all currently supported versions of Ubuntu. In all currently supported versions of Ubuntu, open the terminal and type:
sudo apt install python-pydot python-pydot-ng graphviz # python-pydot-ng isn't in the 14.04 reposThis flowchart was created with graphviz in Ubuntu. Because graphviz uses the built-in dot programming language which is included in the graphviz package, the source code of the linked flowchart is editable in any text editor even if python-pydot is not installed.
I don't know why you would want to install pydot with pip when you can get it from the Ubuntu repositories, but to answer your question I tried installing pydot anyway in a Python virtual environment with pip3 install pydot and it worked, so it is possible that you need to update pip to the latest version with sudo -H pip3 install --upgrade pip. I used pip3 instead of pip because you wrote in your question that you are using Python 3.5.
From this answer on "Installing pydot and graphviz packages in Anaconda environment"
2I had the same issue and solved it by (order is important):
- Installing
graphviz, simply viasudo apt-get install graphviz- Installing
graphvizfor Python via condasudo ~/anaconda2/bin/conda install graphviz- Finally, by installing
pydotusing condasudo ~/anaconda2/bin/conda install pydotThis answer is overdue but this post helped me (together with this one that mentions the installation order), so hopefully this answer will help someone else. I'm using Ubuntu 14.04 and Python 2.7.
P.S. apparently, there could be some issues with step 1 of the above algorithm, this post mentions how to fix them.
Because you use python 3, the right command would be pip3 install pydot graphviz. You can install pip3 using sudo apt install python3-pip.
On Ubuntu 17.10, the ff fixed the issue:
sudo apt-get install python3-pydot graphviz
sudo pip3 install pydot_ng
