How to batch load device into Zenoss5

in Zenoss 4.2, zenbatchdump and zenbatchload worked fine, according to the Zenoss5 Admin Guide, it says to attach the Zenoss.core, then do the samething as previous version. Howerver, it doesn't work at all.

Errors below,

To me, seems like the script is from the old version, as Zenoss5 is not using MySql.
I also tried to load device in.
