Visualize the results of decision trees performed with Python scikit-learn

When I renewed my PC and tried to make a decision tree for the first time, it took me a while to forget how to create a visualization environment. Here, I will describe it with the meaning of my memorandum.

Official page of graphviz From here, go to the Download page and download the stable version below. Graphviz_install.png

Download the .msi file. Double-click this downloaded msi file to install it. Graphviz_wizard.png

command prompt

pip install graphviz
pip install pydotplus
pip_install.png

Then add the directory containing the "dot.ext" file to Path. Open the advanced system settings and click Environment Variables. システムの詳細設定.png

Then add the directory with "dot.ext" to Path. In the case of I C: \ Users \ username \ Anaconda3 \ envs \ virtual environment name \ Library \ bin \ graphviz was. path.png

Now you can visualize it! Treeできあがり.png
