Hello scikit-learn group. I am a beginner to libsvm. I'm having an outlier detection problem. I train the data in the format <label> <index1>: <value1> <index2>: <value2> ... in one-class SVM and get a model file, then I predict test file and model file to get be accuracy. I want to draw one-class borders using the same interface as this article: https://scikit-learn.org/stable/auto_examples/miscellaneous/plot_anomaly_com... but different input got me error (not in type <index:value>). Can you help me? I hope for help in solving this problem. Thank you very much.
