Question

构建我的火车模型时遇到问题。它返回'int'对象是不可调用的。

这是我的代码：

from __future__ import print_function
import keras

from keras.models import Sequential
from keras.layers import Dense, Dropout, Flatten
from keras.layers import Conv2D, MaxPooling2D
from keras.utils import np_utils
from keras import backend as K
import pandas as pd
import numpy as np


# input image dimensions
img_rows, img_cols = 7, 7

# fix random seed for reproducibility
seed = 7
np.random.seed(seed)

x_train = pd.read_csv('palm_3x3_test.csv')
x_train.drop(['class'],axis=1,inplace=True)
x_train = x_train.as_matrix().reshape(-1, 7, 7)

y_train = pd.read_csv('palm_3x3_test.csv')
y_train = y_train[['class']]


x_test = pd.read_csv('palm_3x3_data.csv')
x_test.drop(['class'],axis=1,inplace=True)
x_test = x_test.as_matrix().reshape(-1, 7, 7)

y_test = pd.read_csv('palm_3x3_data.csv')
y_test = y_test[['class']]

# reshape to be [samples][pixels][width][height]
x_train_final = x_train.reshape(x_train.shape[0], 7, 7,1).astype('float32')
x_test_final = x_test.reshape(x_test.shape[0], 7, 7,1).astype('float32')

# normalize inputs from 0-255 to 0-1
x_train_final = x_train_final / 255
x_test_final = x_test_final / 255

# one hot encode outputs
y_train = np_utils.to_categorical(y_train)
y_test = np_utils.to_categorical(y_test)
num_classes = y_test.shape[1]

input_shape = (img_rows,img_cols , 1)

def baseline_model():
#     create model

    model = Sequential()
    model.add(Conv2D(30 (5,5), border_mode='valid', input_shape=(1,(7,7)), activation='relu'))
    model.add(MaxPooling2D(pool_size=(2, 2)))
    model.add(Conv2D(15 (3, 3), activation='relu'))
    model.add(MaxPooling2D(pool_size=(2, 2)))
    model.add(Dropout(0.2))
    model.add(Flatten())
    model.add(Dense(128, activation='relu'))
    model.add(Dense(50, activation='relu'))
    model.add(Dense(num_classes, activation='softmax'))

    # Compile model
    model.compile(loss='binary_crossentropy', optimizer='adam', metrics=['accuracy'])
    return model

# build the model
model = baseline_model()
# Fit the model
model.fit(x_train_final,y_train_final, validation_data=(x_test,y_test), nb_epoch=10, batch_size=200,verbose=2)
# Final evaluation of the model
scores = model.evaluate(x_test,y_test, verbose=0)
print("CNN Error: %.2f%%" % (100-scores[1]*100))

这是错误：

---------------------------------------------------------------------------
TypeError                                 Traceback (most recent call last)

     80 model.fit(x_train_final,y_train_final, validation_data=(x_test,y_test), nb_epoch=10, batch_size=200,verbose=2)

     64     model.add(MaxPooling2D(pool_size=(2, 2)))
     65     model.add(Conv2D(15 (3, 3), activation='relu'))

TypeError: 'int' object is not callable

我尝试搜索相关错误，大部分答案都是关于变量命名冲突函数名称。这个错误的原因是因为我命名变量吗？

Answer 1

中的30之后缺少逗号

   model.add(Conv2D(30 (5,5), border_mode='valid', input_shape=(1,(7,7)), activation='relu'))

这就是为什么它试图使用参数30来调用5,5。

蟒蛇，keras。构建训练模型时出错：TypeError：'int'对象不可调用
