"No motion plan found" for "pick" or "place"

[xibeisiber]

Hi, since in the documentation page the moveit_app_zoo reports 404, I used the code of moveit_example_apps to run the demo.

But I got the warning of "Fail: ABORTED: No motion plan found. No execution attempted." for "pick" or "place".

Before running the demo, I changed the classifier parameters in gpd.launch from "$(find gpd)/launch/caffe/classifier_15channels.launch" to "$(find gpd)/launch/lenet/ur5_classifier_15channels.launch" since I installed the forward version of GPD. I guess this does not influence the demo..

The screenshot is here.

Thanks for any help!
