使用 TensorFlow 作为后端的 keras 出错

Question

I'm at the beginning of my project and I've just imported the packages that I need:

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

Obviously both TensorFlow and keras are already installed. Anyway, if I run the code I get this error:

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

I really don't know how to fix this problem, I've cheked many web sites to follow a correct installetion of the two packages but with no result. I did a correct installation but I still have this error.

You may want to try keras which comes with tensorflow. This keras uses only tensorflow as backend, which is what you need:

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