'str' object has no attribute 'decode' 代码运行时有错误呢？请高手帮忙解决

您好！在程序上具体怎么修改呢？谢谢！见谅，来自python小白的发问 - scdmxy   2018-12-09 19:22

共三处涉及： 第一处： # 统计每个字在男生、女生名字中出现的总次数 lists_male = map(lambda x: x.encode('utf-8'), names_male.decode('utf-8')) counts_male = Counter(lists_male) lists_female = map(lambda x: x.encode('utf-8'), names_female.decode('utf-8')) counts_female = Counter(lists_female) 第二处： # 得到训练集中每个人的每个字的词频（Term Frequency，通常简称TF） train_encoded = [] for i in range(len(train)): name = train.at[i, 'name'] chs = map(lambda x: x.encode('utf-8'), name.decode('utf-8')) row = [0., 0., 0., 0, train.at[i, 'gender']] for j in range(len(chs)): row[2* j] = counts_female[chs[j]] * 1. / f_cnt row[2* j + 1] = counts_male[chs[j]] * 1. / m_cnt train_encoded.append(row) 第三处： # 得到测试集中每个人的每个字的词频（Term Frequency，通常简称TF） test_encoded = [] for i in range(len(test)): name = test.at[i, 'name'] chs = map(lambda x: x.encode('utf-8'), name.decode('utf-8')) row = [0., 0., 0., 0.,] for j in range(len(chs)): try: row[2 * j] = counts_female[chs[j]] * 1. / f_cnt except: pass try: row[2 * j + 1] = counts_male[chs[j]] * 1. / m_cnt except: pass test_encoded.append(row) - scdmxy   2018-12-09 19:28

试试直接去掉.decode('utf-8') - GuoLinhui   2018-12-11 16:20

你好！只有第一处删除后可以运行，后两处都不行，怎么回事呢？感谢！ - scdmxy   2018-12-11 23:52
