The autoML leaderboard is null(and I used the IDE is spyder)

[brucesunxi]

When I use the H2OAutoML, the code like below:
aml = H2OAutoML(max_runtime_secs = 30)
aml.train(x = x, y = y,
training_frame = train,
leaderboard_frame = test)

View the AutoML Leaderboard

lb = aml.leaderboard
lb

but run the lb is null. need your help ,thanks !

I solved this issue by transforming it into dataframe object:

lb = aml.leaderboard.as_data_frame()
print(lb.head())
