     45In virtual robot, if you get a runtime error: ''No module named bs4'', you may need to install the package into the Choregraphe environtment via:
     46{{{
     47sudo pip2 install --target='/opt/Softbank Robotics/Choregraphe Suite 2.5/lib/python2.7/site-packages' \
     48    bs4
     49}}}
     50Use `pip` instead of `pip2` in older linux systems.
     51Beware that the version of just installed `bs4` package may be different from the version on the real robot.
     52
     53A safe option to include new packages is to install the package (e.g. `yourmodule`) in the application directory (e.g. `lib`) and import it like:
     54{{{#!python
     55def __init__(self):
     56        GeneratedClass.__init__(self)
     57        self.folderName = os.path.join(self.behaviorAbsolutePath(), "../lib")
     58
     59def onInput_onStart(self):
     60        if self.folderName not in sys.path:
     61            sys.path.append(self.folderName)
     62        import yourmodule
     63        # ... use yourmodule
     64        if self.folderName in sys.path:
     65            sys.path.remove(self.folderName)
     66        self.onStopped() #activate the output of the box
     67}}}
