文件“F:\anaconda\install\envs\anaconda35\lib\site-packages\keras\backend\tensorflow_backend.py”，第 6 行，在 from tensorflow.python.framework import ops as tf_ops

ImportError: 无法导入名称'ops'

如何解决此错误？

【问题讨论】：

标签： tensorflow machine-learning keras

【解决方案1】：

遇到同样的问题，升级无法解决问题

我解决了：

sudo pip uninstall keras
sudo pip uninstall tensorflow

sudo pip install tensorflow
sudo pip install keras

现在运行良好。

【解决方案2】：

你可以试试这个：

pip install tensorflow --upgrade
pip install keras --upgrade

也许 Keras 框架会检查您的 TensorFlow 后端版本是否太旧。

【讨论】：

谢谢，但他们已升级到最新版本

【解决方案3】：

先尝试卸载：

pip uninstall tensorflow tensorflow-gpu protocol --yes

pip install tensorflow-gpu==1.9.0

pip install keras==2.2.0

【解决方案4】：

使用 pip uninstall 删除 keras，然后使用

安装 keras

conda install keras

如果你有 conda 发行版
