Question

我一直在尝试通过以下教程重新训练Inception： https://www.tensorflow.org/tutorials/image_retraining。我收到此错误“没有名为backports的模块” 当我运行这个

bazel-bin/tensorflow/examples/image_retraining/retrain --image_dir ~/marine_animal_species1

这是完整的追溯：

我使用的是ubuntu 16.04。谢谢你的帮助。

Answer 1

sudo pip install backports.weakref
sudo pip3 install backports.weakref

解决了我的问题。

Answer 2

从backports命名空间安装weakref模块。你可以从https://pypi.python.org/pypi/backports.weakref/1.0rc1＆amp;获得轮盘文件。安装下载的轮子：

sudo pip install backports.weakref-1.0rc1-py2-none-any.whl # python2
sudo pip3 install backports.weakref-1.0rc1-py3-none-any.whl # python3

然后运行你的命令

bazel-bin/tensorflow/...

这可以解决您的问题。
