按照官方的debug文档，还是没有解决  config配置文档在详细一点就好了

---------------------------------------

Out of memory error on GPU 0. Cannot allocate 1.439175GB memory on GPU 0, 22.777100GB memory has been allocated and available memory is only 932.562500MB.

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.
If the above ways do not solve the out of memory problem, you can try to use CUDA managed memory. The command is `export FLAGS_use_cuda_managed_memory=false`.
