训练KIE中的SER训练时产生如下报错，batch_size与num_workers均已调成1仍显存不足，请问如何解决？

Out of memory error on GPU 0. Cannot allocate 937.335938PB memory on GPU 0, 3.078247GB memory has been allocated and available memory is only 7.823547GB.

Please check whether there is any other process using GPU 0.
1. If yes, please stop them, or start PaddlePaddle on another GPU.
2. If no, please decrease the batch size of your model.
