deep learning and keras node errors

Hi,
I posted about deep learning and keras node erros before.
(Deep learning and keras errors)

I didn’t notice the latest reply so I can’t reply anymore.
So I am writing this posting again.

The problem was that the deep learning node works on some computers but not on certain computers.
I got this kinds of error message

ERROR Keras Network Learner 3:13 Execute failed: (“NullPointerException”): null

KNIME log is as follows.

How can I fix this error?

In my log file, there is a message written in Korean.
I’ve translated Korean message into English.

Please check this log message and tell me what is the problem.

Thank you.
