没有名为'_pywrap_tensorflow_internal'的模块错误Python

Question

我将keras库降级为python 3.7，但是当我想运行我的代码时，出现此错误。

import _pywrap_tensorflow_internal
ModuleNotFoundError: No module named '_pywrap_tensorflow_internal'
Failed to load the native TensorFlow runtime.
See https://www.tensorflow.org/install/install_sources#common_installation_problems
for some common reasons and solutions.  Include the entire stack trace
above this error message when asking for help.

我所做的就是编写以下代码：

from keras.callbacks import LambdaCallback
from keras.models import Sequential
from keras.layers import Dense, Activation
from keras.layers import LSTM
from keras.optimizers import RMSprop

我该如何解决这个问题？
