InvocationException: GraphViz's executables not found

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 ( 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) :frowning:
So, I set buildpacks (and some source code modification/update):

  1. heroku buildpacks:set heroku/python
  2. heroku buildpacks:add --index 1

Best regards
