Hello,
i’ve deploying a local web app working ok, but when deploy on Heroku I get this problem “InvocationException: GraphViz’s executables not found”. My app use Graphviz resource (https://graphviz.org/) installed.
Hi @eduardomreal, welcome to the Streamlit community!
What do your setup files look like? Do you have a step where you install GraphViz?
Hi @randyzwitch thank you very much for your replay! I have installed graphviz in my local machine and run ok, but when i run on server it isn’t work. Do you know how i can configure this?
That’s what I’m asking, did you install graphviz on Heroku?
Hi @randyzwitch, thank you again for your attention!
App is working now! I was aking a mistake (only set and not add) 
So, I set buildpacks (and some source code modification/update):
- heroku buildpacks:set heroku/python
- heroku buildpacks:add --index 1 https://github.com/weibeld/heroku-buildpack-graphviz
Best regards
