已经多次询问该错误，答案总是是将\models\research和\models\research\slim添加到路径中。我从一个名为mv的virtualenv环境中运行，并且在运行以下命令时：(mv) D:\training\Tensorflow\models\research\object_detection>echo %PATH%以查看适用于我的环境的路径，我得到以下信息：

正如您在底部看到的那样，这两个目录都在路径上。我也尝试使用\ {search}用python setup.py build和python setup.py install建立目录，但还是没有运气。我要去哪里错了？
