How xlearn process the dataset before using the c++ api "Train(vector<reader>, vector<reader>)” #367

你好,在使用xlearn时,我们会把数据X传给python的fit接口,python会一层层的调用,直到使用底层的c++的train接口,我看这个c++接口使用的是reader数据类型,所以在从python侧调用c++侧的过程中一定会进行数据的处理,我对通过python调用c++这个过程不熟悉,请问如何才能看到这个数据处理都过程?它会包含在哪个文件里吗?最后,像“_LIB.XLearnSetTrain”这样的函数定义在哪个文件里啊?我找不到它,希望您能回复一下,不胜感谢! Thank!
