在简单代码上运行tensorflow时发生错误

Question

在Colab页上，我获取了代码，并尝试在Jupyter Notebook中运行它们。

运行第二个单元格给了我很长很长的错误，我在下面重现（由于要求：包括整个堆栈跟踪 寻求帮助时此错误消息上方）

我不明白这意味着什么，所以我去了Anaconda Navigator，发现tensorflow的安装版本为1.13.1（包括图像）。

我知道存在版本2.0；我想在Anaconda Navigator的tensorflow环境中将2.0升级到base，我认为问题来自旧版本，但是坦率地说，我不知道该怎么做它...

浏览Google时，我遇到了太多信息，以至于无法摆脱它。

有人了解错误消息，还是知道升级tensorflow的简便方法。我会很感激。

错误消息：

以防对某人有用：

我遵循了该站点How to Setup Your Python Environment for Machine Learning with Anaconda的指示，并根据第5点：安装深度学习库，我安装了theano和keras。

然后，在这篇帖子AttributeError: 'Tensor' object has no attribute 'numpy'之后，我使用了附加说明tf.enable_eager_execution()。

因此，我没有必要创建新的环境...

在那之后，我能够在Jupyter Notebook内运行 Colab 中提取的全部代码。
