PaddleClas 车辆属性模型vehicle_attribute_model转onnx并部署

下载paddlepaddle3.0.0

下载paddleclas 2.6.0

实验：  运行前输入：

export FLAGS_enable_pir_api=0    

import paddleclas
model = paddleclas.PaddleClas(model_name="vehicle_attribute")
result = model.predict(input_data="/home/PaddleDetection-release-2.8.1/carimg/car.jpg")
print(next(result))

实验没问题后

替换成下载好的vehicle_attribute_model     inference模型

paddle2onnx --model_dir=./models/ResNet50_vd_infer/ \
--model_filename=inference.pdmodel \
--params_filename=inference.pdiparams \
--save_file=./models/ResNet50_vd_infer/inference.onnx \
--opset_version=10 \
--enable_onnx_checker=True
