### What problem does this PR solve? Supports Ascend layout recognizer. Use the environment variable `LAYOUT_RECOGNIZER_TYPE=ascend` to enable the Ascend layout recognizer, and `ASCEND_LAYOUT_RECOGNIZER_DEVICE_ID=n` (for example, n=0) to specify the Ascend device ID. Ensure that you have installed the [ais tools](https://gitee.com/ascend/tools/tree/master/ais-bench_workload/tool/ais_bench) properly. ### Type of change - [x] New Feature (non-breaking change which adds functionality) |
