code improvement #77
Description
line #39 In dataset.py, Should be "and" rather than "or" in "if (not self.check_preprocess()) or preprocess"?
At first time, preprocess is True, then the processed train,val,test datasets will be created together. When next time execute VideoDataset class, the train,val,test datasets will be overwrited, and create the exactly same datasets.
If change "or" to "and", then there is no redundant overwriting process.
