[web2py] import modules from plugin

[Aurigadl]

as I can import a model from plugin

Example:

myAplication
   =>models
   =>controller
   =>views
  .
  .
  .
  .
    =>plugins_xxx
        => models
             => plugin_xxx.py
        =>modules
             => libs1py
             => libs2.py


In the file models/plugin_xxx.py  I write this:

libs1.py = local_import(libs1.py)
but it generates an error

also I have tried
 libs1.py = local_import("plugin_xxx\\libs1.py)
