Numpy 尝试导入tensorflow\u hub时出现此错误：无法从“tensorflow.python.distribute”导入名称“parameter\u server\u strategy\u v2”

我运行了以下代码：

import tensorflow_hub as hub

我得到了这个错误：

你知道怎么修吗

我使用的是windows 10，Anaconda，Python 3.7，tensorflow版本是2.3.1， numpy版本是1.19.2 tensorflow_轮毂版本为0.10.0

---

tensorflow_hub版本0.8.0也存在同样的错误，我相信您安装的tensorflow估计器版本是错误的：pip包tensorflow 2.3.1需要tensorflow估计器=2.3.0，但是…\site packages\tensorflow\u estimator\python\estimator\run\u config.py的第30行中有问题的导入来自tensorflow estimator 2.4.0。

我也遇到了同样的问题，通过将我环境中的tensorflow estimator版本从2.4.0降级到2.3.0解决了这个问题。我可以在Anaconda Navigator中轻松完成这项工作，但在任何其他环境/软件包管理器中都可以通过使用pip实现这一点：

pip install --upgrade tensorflow-estimator==2.3.0

---

注意：-升级适用于升级和降级。

看起来像python冲突。试过最新版本吗？3.8, 3.9
