1，模型转换 pt------>onnx,代码

onnx_model = model.export(format="onnx", dynamic=False, simplify=True, opset=11)

2， onnx ----> om, 命令：

atc --model=/ultralytics/zwch/electricity/yd_models/yantian/best.onnx --framework=5 --output=yolov1n_atc_zwch --input_shape="images:1,3,640,640"  --soc_version=Ascend310P3 --insert_op_conf=aipp.cfg
