AttributeError: 模塊 'keras.utils' 沒有屬性 'plot_model' 但安裝了 Keras 和 tensorflow

Question

我正在嘗試在 Keras 中繪制深度學習 model 的繪圖/圖表，但它一直給我一個信息量不大的錯誤。

這是我的代碼：

import pandas as pd
forecast_demo = pd.read_csv('forcastdemo.csv')
forecast_demo.head()

X_train = forecast_demo[['index', 'quarter']]
y_train = forecast_demo.revenue
import keras
from tensorflow.keras import Model
from tensorflow.keras import models

from tensorflow.keras.utils import plot_model
from tensorflow.keras.layers import Input, Dense, BatchNormalization
from IPython.core.display import Image

inputs = Input(shape=(2,))              
x = BatchNormalization()(inputs)
x = Dense(512, activation='relu')(x)
x = Dense(128, activation='relu')(x)
x = Dense(64, activation='relu')(x)
x = Dense(32, activation='relu')(x)
outputs = Dense(1)(x)       

model = Model(inputs, outputs)
model.summary()
keras.utils.plot_model(model,to_file='images/oefening2.png', show_shapes=True)
Image('images/oefening2.png')'''

這是我的錯誤信息：

AttributeError: module 'keras.utils' has no attribute 'plot_model

Answer 1

使用此代碼解決：

import tensorflow as tf
from tensorflow import keras
from tensorflow.keras import Model

from tensorflow.keras.utils import plot_model
from tensorflow.keras.layers import Input, Dense, BatchNormalization
from IPython.core.display import Image
