我关于keras ResNet的模型有什么问题

Question

• batch_size = 80
• 纪元= 1000
• num_classes = 26
• validata之前的照片= 60 * 160，=>我想快速训练它=> 32 * 32

原因：我想更改模型以标识code_photo，我的模型正在尝试测试第一个单词

def resnet_v1(input_shape, depth, num_classes):

if (depth - 2) % 6 != 0:
    raise ValueError('depth should be 6n+2 (eg: 20, 32, 44 in [a])')
# Start model definition.
num_filters = 16

inputs = Input(shape=input_shape)
x = resnet_layer(inputs=inputs)
# Instantiate the stack of residual units

    for res_block in range(num_res_blocks):
        strides = 1
        if stack > 0 and res_block == 0:  # first layer but not first stack
            strides = 2  # downsample
        y = resnet_layer(inputs=x,
                         num_filters=num_filters,

        x = Activation('relu')(x)
        #x = LeakyReLU()(x) #改relu -> LeakyReLU
    num_filters *= 2

# Add classifier on top.
# v1 does not use BN after last shortcut connection-ReLU

outputs = Dense(num_classes,
                activation='softmax',
                kernel_initializer='he_normal')(y)

# Instantiate model.

return model
