Then i try to import graphviz, but python shows me the following error No module named 'graphviz'. (I also download the rar package from GraphViz page)
#Install graphviz install#
I already could conda install -c anaconda graphviz in my cmd and conda install -c anaconda pydot and installation was completed. I am not a programmer, i am just an simple economist which is trying to learn machine learning models, so for me is difficult to read much of the solutions provided in other threads. I had read a lot of threads with the same problem as me but i perform much of the solutions but i still cannot perform my decision trees :( I been trying to install graphviz and connect with python to graph some nodes for decision trees.
