Resource exhausted: OOM when allocating tensor  #10

Dr. Wang, thank you so much for your wonderful work.
When I run last step : python main.py, an error occored:

2019-07-15 17:38:14.500279: W T:\src\github\tensorflow\tensorflow\core\framework\op_kernel.cc:1318] OP_REQUIRES failed at conv_ops.cc:673 : Resource exhausted: OOM when allocating tensor with shape[442410,128,9,1] and type float on /job:localhost/replica:0/task:0/device:GPU:0 by allocator GPU_0_bfc

My gpu information is :
