How correctly import graphviz?

Question

When I try to import graphviz package to my project I have error:

ModuleNotFoundError: No module named 'graphviz'

I use Pycharm on Windows. I install package from Settings -> Project Interpreter, but error it's still the same.

I tired python -m pip install graphviz and python3 -m pip install graphviz in CMD, but without result.

My python version is: Python 3.8.1 (tags/v3.8.1:1b293b6, Dec 18 2019, 22:39:24) [MSC v.1916 32 bit (Intel)].

How can I resolve this problem?

What do you mean by "without result"? Does it not install correctly or does it not fix your problem? — funie200, Jan 23 '20 at 20:20
Run this code inside PyCharm and show us the output: `import sys; print(sys.path)` — John Gordon, Jan 23 '20 at 20:26
@JohnGordon the output is https://www.pastiebin.com/5e2a02e40bbc5 — tryToRunThisCommand, Jan 23 '20 at 20:33
Based on that output, it looks like PyCharm expects to find third-party modules installed in `C:\Users\my_user\PycharmProjects\ProjectName\venv\lib\site-packages`. Where is graphvis actually installed? — John Gordon, Jan 23 '20 at 20:51
@JohnGordon It is in `venv\lib\site-packages`. https://imgur.com/a/UdsKpcK — tryToRunThisCommand, Jan 23 '20 at 20:58
Did you install the Graphviz software already? The python graphviz package is just an interface — Chasevanb, Jan 23 '20 at 21:03
@Chasevanb How can I install it? I download zip package from `https://graphviz.gitlab.io/download/` and unpack it, but I don't know what now. — tryToRunThisCommand, Jan 23 '20 at 21:08
@tryToRunThisCommand If you use the zip download, you'll need to set the PATH variable yourself. Otherwise, I believe the MSI installer will set the PATH variable for you: https://graphviz.gitlab.io/_pages/Download/Download_windows.html — Chasevanb, Jan 23 '20 at 21:15
@tryToRunThisCommand May sound silly, but is your virtual environment active? — Chasevanb, Jan 23 '20 at 21:37

The Python graphviz package requires you to have Graphviz software installed. The package itself is just an interface with this software.

The only dependency is a working installation of Graphviz (download page).

I use `pip install graphviz` earlier. When I type it now i have: `Requirement already satisfied: graphviz in c:\users\my_user\appdata\local\programs\python\python38-32\lib\site-packages (0.13.2)`. – tryToRunThisCommand Jan 23 '20 at 21:12
