r - Error when calling h2o predict

Question

When using h2o in R, I get an error when trying to call the predict function on a model object:

Error in .h2o.calcBaseURL(conn = conn, h2oRestApiVersion =    h2oRestApiVersion,  : 
no slot of name "https" for this object of class "H2OConnection"

What's going on?

Edit I noticed since I upgraded to the latest h2o version, I also get this error when trying to load previously created model objects:

Error in .model.parts(o) : 
trying to get slot "metrics" from an object of a basic class ("NULL")  with no slots

H2O 目前不允许您从另一个版本访问在一个版本的 H2O 中构建的模型。换句话说，您只能从最初内置的 H2O 版本访问模型。
