为什么要把所有序列推荐模型训练集进行扩充，希望贵团队能够解答一下这个疑惑，非常感谢。 for i, uid in enumerate(self.inter_feat[self.uid_field].numpy()): if last_uid != uid: last_uid = uid seq_start = i else: if i - seq_start > max_item_list_len: seq_start += 1 uid_list.append(uid) item_list_index.append(slice(seq_start, i)) target_index.append(i)...

前面3600step预测正常 从3600step开始就预测报错，报错如下： File "/mnt/pfs/jinfeng_team/MMGroup/Yaguang/tool/miniconda3/envs/ragDemo/lib/python3.9/site-packages/transformers/generation/utils.py", line 1525, in generate return self.sample( File "/mnt/pfs/jinfeng_team/MMGroup/Yaguang/tool/miniconda3/envs/ragDemo/lib/python3.9/site-packages/transformers/generation/utils.py", line 2658, in sample next_tokens = torch.multinomial(probs, num_samples=1).squeeze(1) RuntimeError: probability tensor contains either `inf`, `nan` or element <...
