Check if a module exists before trying to import it.

from pkgutil import iter_modules


class basic_functions:
    def module_exists( self, module_name):
        return module_name in (name for loader, name, ispkg in iter_modules())

if basic_functions().module_exists( "poser" ):
    import poser
else:
    if basic_functions().module_exists( "POSER_FAKE"):
        import POSER_FAKE as poser
