I am trying to train LSTM network following the example given in mathworks entitled "Classify Videos Using Deep Learning". But I am getting an error. I am attaching here the screenshot of the error.
In this screenshot the error is responses must be a categorical column vector. In my case, as you can see in the code (line no. 154) responses are named as labelsTrain. In the workspace you can see labelsTrain is categorical. I am not getting the reason behind this error and hence unable to find a way out of it. Please suggest some solution for this.
If my query is not clear, feel free to comment.
