cann版本：5.1.RC2

atc 指令：

atc --model=yolov7.onnx --output=yolov7 --framework=5 --input_format=NCHW --soc_version=Ascend310 --insert_op_conf=insert_op.cfg

其中insert_op.cfg 为sample中YOLOV4_coco_detection_picture 中提供的配置文件，yolov7.onnx 可以正常推理，为官方yolov7.pt模型 export 转换生成。

错误信息：

ATC run failed, Please check the detail log, Try 'atc --help' for more information
