The confusion matrix appears and the emotion category except sad emotion category is 0

Hello, Professo, Sorry to be a bother.When we design the network model or use the new loss function to optimize the model, the confusion matrix of the other three categories except sad category will be 0. Have you ever encountered similar situations in the running of the code? Do you know how to solve it? The confusion matrix is shown below: [[0 0 0 126] [0 0 0 89] [0 0 0144] [0 0 0 91]]

@huaminYang Please clear your question. What is meant by new loss function.
