ImportError：无法导入名称“ extract_zipped_pa​​ths”

Question

我正在尝试访问Tensorflow 2.0中列出的数据集。我使用Windows 10。

我已经运行了以下命令：

pip install tfds-nightly

pip install tensorflow-datasets

我PC中的Tensorflow版本为：

2.0.0-alpha0

（尝试将其升级到更新的版本b时遇到异常：

  Found existing installation: wrapt 1.10.11
ERROR: Cannot uninstall 'wrapt'. It is a distutils installed project and thus we cannot accurately determine which files belong to it which would lead to only a partial uninstall.

）

当我尝试导入模块时：

import tensorflow_datasets as tfds

我收到以下错误消息：

Answer 1

删除所有现有的请求版本。并专门安装pip install requests==2.22.0

Answer 2

您需要将请求库的版本降级到2.21.0

pip install requests==2.21.0

我使用tensorflow的'2.0.0-beta1'版本时遇到了完全相同的问题，并且让我pip安装了tensorflow_datasets，这导致了您提到的错误。

我注意到在安装tensorflow_datasets时，requests模块已更新到最新版本2.22.0，尽管该函数在request.utils子模块中定义，但似乎无法导入“ extract_zipped_pa​​ths”。在这里：

https://2.python-requests.org/en/master/_modules/requests/utils/

此外，在没有TF的情况下，请求模块似乎可以正常运行。我不知道问题出在哪里，但是将请求模块降级到2.21.0可以正常工作。

摘要：

tf.__version__ == '2.0.0-beta1'

pip install tensorflow_datasets 

pip install requests==2.21.0
