Question about reading "XXX.train" file #17

Open SK-silver opened 3 years ago

SK-silver commented 3 years ago

Hello! I am now trying to train using a dataset containing Nan. However, I find that the sample provided is in the form of libSVM. Because libSVM only allows numerical values and not Nan. Therefore, I convert the data to a ".npy" file to try. I would like to ask if the provided code supports reading in other files, such as ".npy," ".csv." If it supports it, I would like to get some details about it.
