训练时报错，之前还可以突然出现这个错误

[ainndejj11]

前几天训练还是正常的，今天训练时，就报了这个错误：

[hint: 'cublas_status_invalid_value'. an unsupported value or parameter was passed to the function (a negative vector size, for example). to correct: ensure that all the parameters being passed have valid values. ] (at /paddle/paddle/fluid/platfor

请问这是什么原因？？
