tensorflow2.3版本运行Python深度学习这本书上第六章的例程序出现字符解码错误

import os

imdb_dir = '/home/ubuntu/data/aclImdb'
train_dir = os.path.join(imdb_dir, 'train')

labels = []
texts = []

for label_type in ['neg', 'pos']:
    dir_name = os.path.join(train_dir, label_type)
    for fname in os.listdir(dir_name):
        if fname[-4:] == '.txt':
            f = open(os.path.join(dir_name, fname))
            texts.append(f.read())
            f.close()
            if label_type == 'neg':
                labels.append(0)
            else:
                labels.append(1)

在f = open(os.path.join(dir_name, fname))这句里，打开文件语句中指定编码方式。
添加 encoding='utf-8'或encoding='gbk'试试。
