[ras44]

Describe the bug
Running https://github.com/uber/causalml/blob/master/examples/uplift_tree_visualization.ipynb leads to an error:

InvocationException: GraphViz's executables not found

To Reproduce
Run http://34.171.211.97:8888/doc/tree/examples/uplift_tree_visualization.ipynb

Expected behavior
No error

Screenshots

Environment (please complete the following information):

• OS: [Ubuntu]
• Python Version: [3.8]

Additional context
This looks like a missing dependency on graphviz

[vincewu51]

graphviz has a recurring issue with the env variable issue. It seems to require manual installation for it to work Link
Should we seek alternatives?

@vincewu51 @jeongyoonlee On a clean instance, for me, I was able to resolve with two steps:

conda install python-graphviz

after which there appears to be an issue with libxrender. When I check the ldd dependency resolution, libxrender is not installed:

After installing it with sudo apt-get install -y libxrender-dev, I see beautiful tree plots!

Since libxrender can also be installed through conda, and since we've previously tried to avoid installing system libs manually via apt-get, it appears the solution is:

conda install python-graphviz
conda config --add channels conda-forge
conda install xorg-libxrender

I'd be happy to include a PR that incorporates the fix.

That will be great. Thank you!
