Unable to sortout the mandatory input missing error in the keras apply model. The connections I believe are correct. Have tried a number of things but nothing seems to work. Any suggestion would be highly appreciated.

    Hello @asf - there is a dedicated thread for the Keras extension.  I would recommend reposting there.

    I had a similar issue (NullPointer Exception), which I was able to clear up by having only one Java Runtime on my system (I had two) and making sure the JAVA_HOME environment variable was correctly set (i.e. it pointed to the JRE for the Java Runtime I kept). 


    In Windows you do this through the Windows Control Panel.  Open the System Applet  --> Advanced system Settings  --> Environment Variables.


    If you update your Java runtime, update your JAVA_HOME environment to point to your updated JRE.


    Hope this works for you.
