解决： DECODER_ERROR_CLASSES += (brotli.error,) ttributeError: module 'brotli' has no attribute 'error'

注释掉：E:\anaconda\envs\TF_2C\Lib\site-packages\pip\_vendor\urllib3\response.py中的这两行：

 #if brotli is not None:
     #   DECODER_ERROR_CLASSES += (brotli.error,)

　　然后去

下载：

• brotlipy?0.7.0?cp37?cp37m?win_amd64.whl
• pip install ./brotlipy?0.7.0?cp37?cp37m?win_amd64.whl即可，然后就可以：执行安装tensorflow2.0.0的命令了
