UDADataset的__getitem__问题 #15

Closed wzr0108 closed 1 year ago

wzr0108 commented 1 year ago 
    def __getitem__(self, idx):
        if self.rcs_enabled:
            return self.get_rare_class_sample()
        else:
            s1 = self.source[idx // len(self.target)]
            s2 = self.target[idx % len(self.target)]
            return {
                **s1, 'target_img_metas': s2['img_metas'],
                'target_img': s2['img']
            }

为什么源域和目标域的索引，一个是//一个是%？
