Keras: "RuntimeError: Failed to import pydot." after installing graphviz and pydot
The error message is a bit misleading, as you can see here. The problem is that graphviz is not installed.
But you mention that graphviz was installed using pip. This is also misleading, since that graphviz package is just a python wrapper, and the graphviz binaries have to be installed separately for the python wrapper to work.
If you are using an Anaconda environment, you'd better install pydotplus and graphviz via conda install.
conda install graphvizconda install pydotplusNote:You'd better update your Keras to the newest version (2.0.9+), it can automatically check and choose which one of pydotplus,pydot-ng,pydot to be used. pydot-ng has been unmaintained for a long time, and it only supports py3.4- and py2.7.
