002_sparse_one.py第228行
data = pd.read_csv('train_test_merge.csv')
这一行报错, 文件不存在, 这里应该在文件前面加上路径吧.
大神的代码写得很赞...编排也很用心,感谢!
test2数据集
哈喽，你好，想问一下，数据集你还留着吗？我从官网上下载下来的数据集中，没有test2 ，你能发我一份test2的数据集不，感谢！！！
求数据集哈
在文件底下 没有找到相应的数据集
关于转化率特征部分的问题
作者您好，想请问下在构造转化率特征的过程中，为什么要-400？
如下代码
df_feature[col_name] = ((pd.Series(data.index).map(se)*10000)-400).fillna(value=-1).astype('int')
col_select
你好，请问下005_cvr_select_2.py代码中的col_select是在哪里定义的？运行出错了。。。
