Load Model Error: java.lang.UnsupportedOperationException: empty collection

[juzheng-zhang-1989]

Hi Team,

I compiled the project for spark 2.4 following the instructions at homepage. It has been built successfully and passed all tests. But I still got the error below when I try to load trained model (model save can work). Any one can help?

Regards,
James
