When you do

import plugins.name1.name1

then "plugins" and "plugins/name1" should be a package, not a module. A 
package is a special directory that contains package initialization code 
in a __init__.py file. If you do not have the file, then the "plugins" 
directory will be only a directory, and it cannot be imported.
