if you code doesn´t work, you can use this.

import graphviz
from IPython.display import display
with open("tree1.dot") as f:
dot_graph = f.read()
display(graphviz.Source(dot_graph))

Reinstall graphviz

conda remove graphviz 
conda install python-graphviz
graphviz.Source(dot_graph).view()

after you will have a small window where you have to choose where you want see your decision tree

the following worked for me (removal in Jupyter via 'conda remove graphviz' didn't work):

go to Anaconda Navigator Console:

-->Environments--> Search for graphviz --> deinstall

-->Environments --> install python-graphviz
