我是Python和Tensorflow的新手。在执行tfds.load函数时，我得到了以下错误。我花了几个小时试图理解这个错误，但我不知所措。如有任何帮助，我们将不胜感激。我使用以下版本：python 3.8、tensorflow 2.3和tensorflow数据集1.2

将tensorflow数据集从
1.2升级到4.2后，问题是解决。(转述自Niteya Shah(
我也遇到了问题，这将解决问题：
pip install tensorflow-datasets=4.3
我遇到了同样的问题，我的解决方案，只使用创建了一个新环境
conda create --name py3-TF2.0 python=3
conda activate py3-TF2.0
pip install --upgrade pip
pip install tensorflow
pip install --upgrade tensorflow
pip install tensorflow-datasets
pip install ipykernel
