请问DataProcessor类在哪里呢

[sweetboxwwy]

processors = {
        "xnli": XnliProcessor,
        "tnews": TnewsProcessor,
        "afqmc": AFQMCProcessor,
        "iflytek": iFLYTEKDataProcessor,
        "copa": COPAProcessor,
        "cmnli": CMNLIProcessor,
        "wsc": WSCProcessor,
        "csl": CslProcessor,

}
我想要根据这几个类重写一个读取自己数据集的类，在哪里找到这几个类的写法呢
