keras_model ERROR: Execution of python script failed

Hi all,
I installed keras_model on rapidminer. I uploaded the sample file "boston_housing_prices_regression" but in the block Keras_model I get the following error: "Execution of python script failed
Please check yout python script: ODError: 'pydot' failed to call GraphViz.Please install GrapghViz (http://www.graphviz.org/) and ensure that its executables are in the $PATH.(script, line 197)"

In python: "C: \ Program Files \ Python35 \ Lib" I have the latest version of GrapghViz
and I checked it by opening the prompt and typing: "pip3 install graphviz --upgrade".

Finally I checked "pydot" and "dask" as well.
I encountered the same problem as this post that has not been solved, but I'm not using Anaconda.

I had the same problem but there is a solution. Take a look at this. Are you running Windows or Linux? When I mention downloading Graphviz, I am talking about the Graphviz application itself.
