Python 导入错误：无法导入名称'_断言"浅"结构'；从'；树&x27；

我在IDLE（默认python编辑器）中导入tensorflow_概率时遇到了这个错误。如果在VS代码中使用相同的代码，我不会得到那个错误。在VS代码中工作得非常好。 这是我的进口货

import numpy as np
import tensorflow.compat.v1 as tf
import tensorflow_probability as tfp
tf.disable_v2_behavior()

这里是完全错误

Windows机器

看看它从何处导入（C:\Users\aaaa\AppData\Local\Programs\Python\Python38\Lib\idlelib\tree.py）我想你是想从dm tree导入

以下是我的解决方案： 如果没有安装dm tree

pip install dm-tree

---

如果这样做，请安装PyCharm并使用它来运行代码。它不会与IDLE在树上产生冲突。py

这是正确的文件吗？

“C:\Python Scripts\pos\u tagging.py”

，我问这个问题的原因是，根据你的帖子，你没有从树导入这个

。\u assert\u shallow\u structure

C:\Python Scripts\pos\u tagging.py是我试图运行的。我还没有导入“从树导入-断言-浅层结构”，我不知道它为什么会出现。
