ImportError:无法使用TensorFlow深度学习colab导入名称“maxpool_2d”

我是猫和狗分类器的初学者。我的代码如下：

import tflearn
from tflearn.layers.conv import conv_2d,maxpool_2d
convnet=conv_2d(convent,32,5,activation='relu')
convent=max_pool_2d(convent,5)

在GoogleColab中运行此程序时，我遇到了以下错误。请帮忙

它应该是max_pool_2d而不是maxpool_2d 您正在将convnet设置为传入的张量参数，但之前没有声明它。 train_file=import zipfile with zipfile.ZipFiletrain_file，'r'as z:z.extractall-->表示未找到此类文件目录，且未定义train_数据……我该怎么办？
