flush() failed: stream is closed when save model

[y3zha]

I run MethodBodyCodeLearner.java but when save model it crashed and say

Exception in thread "main" java.io.IOException: flush() failed: stream is closed
the method ModelSerializer.writeModel(model, locationToSave, saveUpdater);

This method is provided by derplearning4j, I don’t know what went wrong and how to handle

I am sorry, I don't know what is the problem. I never met this exception.
If you do not need to store this model, you can remove the code.
