Was executed, but it did not improve.
In the first place, the first line
pip uninstall pydot2At the time of
pydot2I gave up because there was no such thing, and then the second line
pip install pydot>= 1.2.3.However, a mysterious file with no extension written as "1.2.3" was created in the current directory.
Answer # 1
#Create a new dot file or update an existing one export_graphviz (...) # Read the created dot file with open (dir_path +'tree.dot') as file: dot_graph = file.read () # Throw the read dot file to Graphviz's Source graph_source = graphviz.Source (dot_graph) #Rendering graph_source.render (filename = dir_path +'tree', format ='png')
By doing this, I was able to create a png file.
Also, as mentioned above, when rendering, you can specify the path you want to save by connecting the directory path to the file name.
(If not specified, it will be saved in the current directory)
In addition to the png file, the rendering also creates an object (?) With the same file name.
In the above case,
Will be generated.
