Hello Mike, I have trouble with parse method when model is loaded, it throws null pointer wxception in LibLinearModel.java on line 43, here is my stack trace:

What does your command line input look like? You might be missing the parameter "-externalNNs", which causes the system to call a logistic regression classifier instead of the neural network model.

Thank you Mike, I added this parameter and it works now :-) 👍
