Tensorflow版本是2.6.1，keras版本是2.7
Tensorflow2.6 的发行说明中，Keras 被拆分为单独的 PIP 包（keras），其代码已移至 GitHub 存储库 keras-team/keras。tf.keras 的 API 端点保持不变，但现在由 keras PIP 包支持。tensorflow/python/keras 中的现有代码是一个陈旧的副本，将在未来版本 (2.7) 中删除。请删除对 tensorflow.python.keras 的任何导入，并将它们替换为公共 tf.keras API。

解决方案：pip install keras==2.6.0
