I’ve been playing around with SciKit-Learn’s decision tree regression function. In one of the examples I was working on, they provided a demo script to print out a jpg of the decision tree. Cool! Unfortunately, my system didn’t have pydotplus installed. I’m using Anaconda, so issuing the following command took care of that issue:
conda install -c conda-forge pydotplus
However, when attempting to run again, this produced and error stating that the GraphViz executable could not be found. Ugh. Luckily, a quick trip to Homebrew took care of that issue:
brew install graphviz
Voila!
