突然的Tensorflow / Keras Google Colab依赖问题` `AttributeError:模块'tensorflow._api.v1.compat.v2‘没有属性'__internal__'`

Question

我在google colab上运行了几个星期的机器学习模型(Matterport's Mask R-CNN)。今天，我突然不能运行我的任何笔记本，因为我想是某种依赖不匹配错误。完整错误如下：

我怎样才能让我的环境再次工作？

Answer 1

当我尝试这样做时，我解决了这个问题：

!pip uninstall keras-nightly
!pip uninstall -y tensorflow

然后安装tensorflow和kerass，并使用您想要使用的版本

Answer 2

我自己也有这个问题，我也在使用Matterport的Mask-RCNN和google colab。对于我的情况，我修复它的方法是安装以下版本的keras和tensorflow并重新启动运行时：

!pip安装keras==2.3.0 !pip安装tensorflow==1.15.0rc2

我希望这对你也适用。

Answer 3

!pip uninstall keras-nightly
!pip install h5py==2.10.0

我将此代码添加到我的代码顶部，现在问题就解决了。我怀疑这个问题是由keras-nightly的最新更新引起的。
