PhBdZddlmZdgZy)a Unified place for determining if external dependencies are installed or not. You should import all external modules using the import_module() function. For example >>> from sympy.external import import_module >>> numpy = import_module('numpy') If the resulting library is not installed, or if the installed version is less than a given minimum version, the function will return None. Otherwise, it will return the library. See the docstring of import_module() for more information. ) import_modulerN)__doc__sympy.external.importtoolsr__all__bC:\Users\daisl\Desktop\realtime-object-detection\venv\Lib\site-packages\sympy/external/__init__.pyr s"5  r
