PP-YOLO模型，使用C++推理，CreatePredictor 报如下错，哪位大神帮忙看一下什么原因

主要是模型方面问题还是部署方面的问题

看报错信息你是使用TensorRT预测，TensorRT预测需要安装的Paddle版本是带TensorRT编译的，目前默认发布的whl包是不带TensorRT的，如果想用TensorRT预测需要编译一下Paddle，编译时使用-DTENSORRT_ROOT指定一下TensorRT路径，编译方法参考 https://www.paddlepaddle.org.cn/documentation/docs/zh/install/compile/fromsource.html

使用C++预测也需要重新编译paddle吗
