PaddleDetection版本:2.0 beta serving 版本:0.4 paddlepaddle-gpu : 2.0.0rc1 用serving方式部署了一个基于私有数据集的MaskRcnn模型,测试如下(采用多线程同时发送http请求方式): 1)全部用只有背景的图片测试,正常工作。 2)全部用带有目标的图片测试,正常工作,检测结果正常,目标都能检出。 3)混合有目标的图片和没有目标的背景图片测试,出现如下错误 ERROR 2021-03-19 12:09:25,110 [operator.py:733] (data_id=19 log_id=19) [bill_det|0] Failed to process(batch: [19]): In user code:

请问是在导出模型时报错吗?看你的报错信息都是报在导出模型时报错

不是的,导出模型没有报错,只是有warning,是运行的时候出错的。导出模型的log如下: python tools/export_serving_model.py -c configs/mask_rcnn_r50_vd_fpn_2x_bill.yml -o use_gpu=true weights=/home/sy/work/ocr_car/PaddleDetection-release-2.0-beta/output/mask_rcnn_r50_vd_fpn_2x_bill/model_final --output_dir=mask_test_model

请问使用的是静态图还是动态图? 建议您尝试一下 paddleserving 0.5 版本

hymanzhu1983 commented 3 years ago

在paddleserving0.4环境下调用tools/export_serving_model.py,生成的模型有很多文件,诸如bbox_pred_b/fpn_inner_res2_sum_lateral_w/fpn_inner_res3_sum_lateral_b之类,升级paddleserving 0.5后,调用tools/export_serving_model.py,生成的模型是paramsmodel两个文件。请问模型的使用方式有什么不同吗? 我跑原来的程序,报错如下: python web_service.py /home/sy/.conda/envs/maskrcnn-paddle-2.0/lib/python3.7/site-packages/paddle_serving_server_gpu/pipeline/pipeline_server.py:339: YAMLLoadWarning: calling yaml.load() without Loader=... is deprecated, as the default Loader is unsafe.

ExternalError:  Cuda error(77), an illegal memory access was encountered.
  [Advise: The device encountered a load or store instruction on an invalid memory address. This leaves the process in an inconsistentstate and any further CUDA work will return the same error. To continue using CUDA, the process must be terminated and relaunched. ] (at /paddle/paddle/fluid/platform/stream/cuda_stream.cc:65)
