python - 使用 TensorFlow 作为后端的 keras 出现错误

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 都已安装。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，我检查了很多网站以正确安装这两个软件包，但没有结果。我进行了正确的安装，但仍然出现此错误。

你可能想尝试一下tensorflow自带的keras。这个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
