使用biaobei数据集，train在step9980时这样报错，请问我应该从哪里开始修改呢

[sisibeauty]

RuntimeError: cannot reshape tensor of 0 elements into shape [0, 39, -1] because the unspecified dimension size -1 can be any value and is ambiguous

[ranchlai]

1. 检查输入是否有空行。
2. 可以在报错的地方加入 try: 出错行 except: import pdb;pdb.set_trace()

然后进行调式模式看为啥出错

[Moonmore]

RuntimeError: cannot reshape tensor of 0 elements into shape [0, 39, -1] because the unspecified dimension size -1 can be any value and is ambiguous

我也碰到这个一摸一样的问题，按照@ranchlai 的做法没得到解决，请问你现在解决了吗？
