To have all batch sizes executed by CudaGraph, ```max_capture_batch_size``` value should match ```max_num_seqs```. ```max_capture_batch_size``` > ```max_num_seqs``` will cause waste by capturing batches that won't be encountered during inference, occupying more time and memory.

 - 当开启 ```use_cudagraph``` 后，size小于等于 ```max_capture_batch_size``` 的batch会由CudaGraph来执行前向计算，大于 ```max_capture_batch_size``` 的batch会由原本的动态图/静态图执行前向计算。如果希望所有batch size均由CudaGraph来执行，```max_capture_batch_size``` 的值建议与 ```max_num_seqs``` 一致。```max_capture_batch_size``` 大于 ```max_num_seqs``` 会导致浪费，会多捕获一些推理时不会遇到的batch，占用更多时间与显存。
