Hi friends of Hailo,
klaus@penguin:~/Hailo_DataFlow-Compiler$ sudo pip install hailo_dataflow_compiler-3.29.0-py3-none-linux_x86_64.whl
on a Debian 12.7 and
klaus@penguin:~/Hailo_DataFlow-Compiler$ pyenv versions
system

  • 3.10.15 (set by /home/klaus/Hailo_DataFlow-Compiler/.python-version)
    failed with the attached errors.
    Any ideas on what I can do to get Dataflow Compiler to work?
    Thanks,
    Klaus

Hey @Klaus ,

Welcome to the Hailo Community!

The error fatal error: graphviz/cgraph.h: No such file or directory means pygraphviz can’t find the required Graphviz development headers. Let’s fix this:

  1. First, install Graphviz development libraries:
sudo apt-get update
sudo apt-get install graphviz graphviz-dev
  1. Then try installing the Hailo Dataflow Compiler again:
sudo pip install hailo_dataflow_compiler-3.29.0-py3-none-linux_x86_64.whl
  1. If you get compiler errors, make sure gcc is installed:
sudo apt-get install build-essential
  1. Since you’re using pyenv, verify you’re on the correct Python version:
pyenv shell 3.10.15

This should resolve the installation error. Let me know if you need any further help.

Thanks omria! Your first two steps were sufficient to install the Hailo Dataflow compiler. Your help is very much appreciated.
