I am writing a python script using Graphviz. And i am using Pyinstaller to gennerate a .exe file like this: ![image](https://global.discourse-cdn.com/graphviz/original/2X/9/97be0f905dfd98af9acb7d019a9521958ce16e7b.png) My code is like this: ![image](https://global.discourse-cdn.com/graphviz/original/2X/4/4ec3a4c5b8fe91b96ba2b2a06133129668e931a2.png) It works fine in my local environment, but when i run the .exe file in another environment that doesn’t install Graphviz,it will show error like this: > graphviz.backend.execute.ExecutableNotFound: failed to execute WindowsPath(‘dot’), make sure the Graphviz executables are on your systems’ PATH > [13228] Failed to execute script ‘GraphvizTest’ due to unhandled exception! Is there any way to pack Graphviz using Pyinstall? Thanks! ---

Graphviz (dot) is a separate executable binary, not python code. You should ask the PyInstall people about bundling executables, we don’t know anything about PyInstall here.
