Tigychen

Hi all,

I installed rapidminer in Ubuntu 14. I test python scripting and keras in rapidminer and it say python 3.4.3 is detected (as expected).

Then, I run the examples of keras extension. The script stoped abnormally, the log message is as below:

似乎那problem is that graphviz and pydot cannot be imported. However, I tried to import both of them in python and successeeded

There is an extra component that needs to be installed.

From the python graphviz installationinstructions.

To render the generated DOT source code, you also need to install Graphviz (download page).

Make sure that the directory containing the dot executable is on your systems’ path.
