Keras: How to install graphviz ?

[ghost]

Hello!

If use this
from keras.utils.visualize_util import plot
plot(model, to_file='model.png')

will rise an error that
from keras.utils.visualize_util import plot
File "build\bdist.win-amd64\egg\keras\utils\visualize_util.py", line 12, in <module>
RuntimeError: Failed to import pydot. You must install pydot and graphviz for pydotprint to work.

I can import pydot
But print pydot.find_graphviz() is None

How to install graphviz ?

I try to install graphviz-2.38.msi , after that pip install graphviz
But print pydot.find_graphviz() is still None

Thanks a lot!

You have to add the path of GraphViz' \bin folder (for example, it's C:\Program Files (x86)\Graphviz2.38\bin for me) to the PATH environment variable.

btw, your problem has nothing to do with Keras _at all_.
