Plot ROC curve of H2O in Python (one and multiple curves)

Question

I am using H2O in python to make a Generalized Linear Model, binary classification problem, I made the model using

glm_fit_lambda_search = H2OGeneralizedLinearEstimator( family='binomial', 
                                      model_id='glm_fit_lambda_search', 
                                      lambda_search=True )

glm_fit_lambda_search.train( x = x, 
                         y = y, 
                         training_frame = trainH2O, 
                         validation_frame = testH2O )

Now I want to plot the ROC curve of the model, how can I do that?

Also I want to plot multiple ROC curves for comparison

Here is the question in R, How to directly plot ROC of h2o model object in R, How can I do this in python?

Answer 1

try this:

performace = glm_fit_lambda_search.model_performance(train=True)
performace.plot()

should work in theory, I'm not able to verify right now. This will plot the performance on the "train" set.
