Hello, Yipei,

You can use entry point inspector to check whether there is some error in the plugin registration and loading:

sudo pip install entry_point_inspector

epi group list

epi group show <your plugin group>
epi ep show <your entry point>


If there is some error when loading the plugin, you may find error information the show command.

Best Regards

Subject: [tricircle] About registering and loading a plugin

Dear all,

Recently, I learn to name a plugin based on the doc http://docs.openstack.org/developer/stevedore/tutorial/naming.html#. I define a new entry_point for the plugin, then it fails. The console prompts "stevedore.exception.NoMatches: No 'net.nyp.formatter' driver found, looking for 'simple'". After setting a new entry_point with setuptools, why stevedore cannot find the driver based on the entry_point?

Best regards,
