将csv文件转化为Qlib的数据格式https://qlib.readthedocs.io/en/latest/component/data.html#converting-csv-format-into-qlib-format 注意每支股票都要保存成单独一个文档且文档名字与股票代号一致。 其中factor 也就是 https://crm.htsc.com.cn/doc/2020/10750101/d287ebf2-7f3f-4382-bf3f-cfabd4b90161.pdf中提到的复权。

from qlib.data.dataset.loader import QlibDataLoaderMACD_EXP (EMA($close, 12) - EMA($close, 26))/$close - EMA((EMA($close, 12) - EMA($close, 26))/$close, 9)/$closefields [MACD_EXP,$close] # MACDnames [MACD,收盘价]labels [Ref($close, -2)/Ref($close, -1) - 1] # labellabel_names [LABEL]data_loader_config {feature: (fields, names),label: (labels, label_names)}data_loader QlibDataLoader(configdata_loader_config)df data_loader.load(instrumentsall, start_time2010-01-01, end_time2017-12-31)print(df)使用Qlib时候直接使用 Data Handler 是上面 QlibDataLoader 的封装所以Data Handler 也自然可以使用label的设置。
一个完整的例子
from qlib.data.dataset import DatasetH
# 实例化Data Loader
market sh000300 # 沪深300股票池代码在instruments文件夹下有对应的sh000300.txt
close_ma [EMA($close, 10), EMA($close, 30)] # EMA($close, 10)表示计算close的10日指数加权均线
ma_names [EMA10, EMA30]
ret [Ref($close, -1)/$close-1] # 下一日收益率, Ref($close, -1)表示下一日收盘价
ret_name [next_ret]
qdl_ma_gp QlibDataLoader(config{feature:(close_ma, ma_names), label: (ret, ret_name)}) # 实例化Data Handler

from qlib.data.dataset.handler import DataHandlerLP自定义 https://blog.csdn.net/qq_37373209/article/details/125224210
所以 最后其实是可以直接用 DatasetH 来设置的
Alpha360:
其data_loader 是指定了feature的不可改变 但是label 是可以从kwargs里边导入的。所以想要用自己的alpha 因子得从data_loader 开始写起而不能直接使用这个类
