安装后没有名为“ tensorflow_examples”的模块

在笔记本的第一个单元格中，我写道：

!pip install git+https://github.com/tensorflow/examples.git
!pip install -U tfds-nightly

在下一个单元格上：

import tensorflow as tf
from tensorflow_examples.models.pix2pix import pix2pix

但这给了我：ModuleNotFoundError：没有名为'tensorflow_examples'的模块

Notebook - version : 6.0.3
Tensorflow - version : 2.0.0

我是否需要安装其他一些模块？

这是pip安装日志：
