使用 TensorFlow 作为后端的 keras 出错

Question

我正处于项目的开始阶段，我刚刚导入了我需要的包：

from keras.models import Sequential
from keras.layers import Dense

显然 TensorFlow 和 keras 都已经安装好了。 无论如何，如果我运行代码，我会收到此错误：

Using TensorFlow backend.
ERROR:root:Internal Python error in the inspect module.
Below is the traceback from this internal error.

我真的不知道如何解决这个问题，我检查了许多网站以遵循两个软件包的正确安装，但没有结果。 我做了正确的安装，但我仍然有这个错误。

您可能想尝试 tensorflow 附带的 keras。 此 keras 仅使用 tensorflow 作为后端，这正是您所需要的：

import tensorflow as tf
from tf.keras import Sequential
from tf.keras.layers import Dense
