【解決方法】Modulenotfounderror: ‘keras.utils.multi_gpu_utils’ という名前のモジュールがありません

私はanaconda Spyderでこのコードを実行しようとしています

import tensorflow as tf
from tensorflow.python import keras
from keras.models import Model
from keras.models import load_model
from keras.optimizers import Adam
from keras.layers import Input, Conv2D, UpSampling2D, Dropout, LeakyReLU, BatchNormalization, Activation, Lambda
from tensorflow.keras.layers import Concatenate
from keras.applications import VGG16
from keras import backend as K
from keras.utils.multi_gpu_utils import multi_gpu_model  --->error

このコードはこの行でエラーを出しています

from keras.utils.multi_gpu_utils import multi_gpu_model

エラーは

ModuleNotFoundError: No module named 'keras.utils.multi_gpu_utils'

この問題を解決するにはどうすればよいですか?

私が試したこと：

tensorflow-gpu をインストールするためのコマンドを実行しました

pip3 install tensorflow-gpu

しかし、次のエラーが発生し、実行が停止します
