ImportError：无法从“tensorflow.python.keras.layers.normalization”不匹配版本中导入名称“LayerNormalization”修复？

Question

没有在 stackoverflow 和 tensorflow 上发布太多内容。我按照本教程学习了如何安装 tensorflow 以在 jupyter 笔记本上使用 (https://github.com/jeffheaton/t81_558_deep_learning/blob/master/install/tensorflow-install-mac-jan-2021.ipynb)。

在测试环境时，我得到 Python 3.8.11、Tensor Flow 2.5.1 和 Keras 2.5.0

我正在尝试运行的代码：

import pandas as pd
import numpy as np
import tensorflow as tf
import re
from nltk.corpus import stopwords
from sklearn.model_selection import train_test_split
from sklearn.metrics import median_absolute_error as mae
from sklearn.metrics import mean_squared_error as mse
from sklearn.metrics import accuracy_score as acc
import matplotlib.pyplot as plt

from keras.models import Sequential
from keras import initializers
from keras.layers import Dropout, Activation, Embedding, Convolution1D, MaxPooling1D, Input, Dense, Merge, \
                         BatchNormalization, Flatten, Reshape, Concatenate
from keras.layers.recurrent import LSTM, GRU
from keras.callbacks import Callback, ModelCheckpoint, EarlyStopping, ReduceLROnPlateau
from keras.models import Model
from keras.optimizers import Adam, SGD, RMSprop
from keras import regularizers

我得到的错误是

ImportError: cannot import name 'LayerNormalization' from 'keras.layers.normalization' (/opt/miniconda3/envs/tensorflow/lib/python3.8/site-packages/keras/layers/normalization/__init__.py)

我知道有帖子称版本不匹配是导致此功能无法正常工作的原因，但不确定我将如何独立更改 tensorflow 等的版本以使其正常工作。

Answer 1

使用 Tensorflow 2.5 和 Keras 2.4.3 再试一次。
