tensorflow2图像分割pix2pix库环境配置问题记录

tensorflow2图像分割环境配置：

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

import tensorflow_datasets as tfds
tfds.disable_progress_bar()

from IPython.display import clear_output
import matplotlib.pyplot as plt

主要是“from tensorflow_examples.models.pix2pix import pix2pix”这句环境配置问题

pycharm中搜索不到这个库：

而使用pip安装提示如下：

pip install -q git+https://github.com/tensorflow/examples.git  错误提示

 

D:\PycharmProjects\pythonProject\venv\Scripts>pip install -q git+https://github.
com/tensorflow/examples.git
  ERROR: Error [WinError 2] 系统找不到指定的文件。 while executing command git c

ERROR: Cannot find command 'git' - do you have 'git' installed and in your PATH?

根据提示，我们升级一下pip为21.1.3版本

点击+号添加库：

点击“Install Package”。

pycharm安装git，点击test提示没有安装git，点击下载安装。

安装失败：

进入官网下载一个安装：

https://git-scm.com/download/win

下载最新版本试试：Click here to download manually

安装，一路下一步，无数配置选项窗口，一路默认。

这里可以参考：GitHub教程 Git Bash详细教程

pycharm配置：

重新安装“pip install -q git+https://github.com/tensorflow/examples.git”，继续报错

重新运行一遍，后面就没反应了。

搞了这么久还是有问题

后面又用手机网络下载试试，成功安装上了。
