Quantization model deploy on GPU about fastdeploy

Please check the docs of YOLOv7End2EndORT:

• vision/detection/yolov7end2end_ort

This class does not support TRT backend. To support TRT::EfficientNMS_TRT op, you should use YOLOv7End2EndTRT, please refer to:

• vision/detection/yolov7end2end_trt

export yolov7 with trt nms (let max-wh be None):

wget https://github.com/WongKinYiu/yolov7/releases/download/v0.1/yolov7.pt

# Export onnx format file with TRT_NMS (Tips: corresponding to YOLOv7 release v0.1 code)
python export.py --weights yolov7.pt --grid --end2end --simplify --topk-all 100 --iou-thres 0.65 --conf-thres 0.35 --img-size 640 640
# The command to export other models is similar Replace yolov7.pt with yolov7x.pt yolov7-d6.pt yolov7-w6.pt ...
# When using YOLOv7End2EndTRT, you only need to provide the onnx file, no need to transfer the trt file, and it will be automatically converted during inference

or download from vision/detection/yolov7end2end_trt .

@DefTruth Thanks I noticed the problem.

Another interesting thing that I quantize of the exported to onnx (small object detection / visdrone paddle) and its succesfully QUint8 and inferencin.

Problem is qunatized onnx much more slower than the orignal fp32.. 10 times.

Meanwhile I will give a shot to int8 chip (hailo-8)
To export onnx some converter asks for calibration images as in
weights=https://paddledet.bj.bcebos.com/models/ppyoloe_crn_l_80e_sliced_visdrone_640_025.pdparams

How can I quantize with calibration ? weights=https://paddledet.bj.bcebos.com/models/ppyoloe_crn_l_80e_sliced_visdrone_640_025.pdparams

Best

Inference with CPU or GPU while you use the quantized onnx model?

[MyraBaba]

@jiangjiajun inferencing with GPU 2080Ti

[jiangjiajun]

Which tool you are using to quantize your onnx model?

[MyraBaba]

@jiangjiajun
onnx:

`from onnxruntime.quantization import quantize_dynamic, QuantType

model_fp32 = '/Users/tulpar/Project/devPaddleDetection/sliced_visdrone.onnx'
model_quant = '/Users/tulpar/Project/devPaddleDetection/88quant_sliced_visdrone.onnx'
# quantized_model = quantize_dynamic(model_fp32, model_quant)
_quantized_model = quantize_dynamic(model_fp32 , model_quant , weight_type=QuantType.QUInt8)
`

[jiangjiajun]

This quant tool is not supported by TensorRT now, Refer this doc https://onnxruntime.ai/docs/performance/quantization.html#quantization-on-gpu

[yunyaoXYY]

@jiangjiajun onnx:

`from onnxruntime.quantization import quantize_dynamic, QuantType

model_fp32 = '/Users/tulpar/Project/devPaddleDetection/sliced_visdrone.onnx'
model_quant = '/Users/tulpar/Project/devPaddleDetection/88quant_sliced_visdrone.onnx'
# quantized_model = quantize_dynamic(model_fp32, model_quant)
_quantized_model = quantize_dynamic(model_fp32 , model_quant , weight_type=QuantType.QUInt8)
`

Hi, FastDeploy will provide the tools to quantize model, which could suit deployment on FastDeploy better. See current tutorials as : https://github.com/PaddlePaddle/FastDeploy/tree/develop/tools/quantization. And we will release the examples about how to deploy INT8 models (YOLO series) on FastDeploy in tow days.

What model do you want to quantize and deploy on FastDeploy? We would give you supports.

@jiangjiajun

The model is : https://paddledet.bj.bcebos.com/models/ppyoloe_crn_l_80e_sliced_visdrone_640_025.pdparams

We have a competition for a huge project for object detection as in above model exactly. But we need to achieve 100fps minimum on the Xavier NX at 640x480 px.

Accuracy is perfect for above model. Neet to speed up and achive the performance.

This is why I tried to quantize int8.

I tried cpp inference 👍
./main --model_dir=/data/dProjects/devPaddleDetection/output_inference/ppyoloe_crn_l_80e_sliced_visdrone_640_025 --video_file=/data/RTSP_oz/20221010_14_30:00_rtsp029.mp4 --device=gpu --run_mode=trt_int8 --batch_size=8 --output_dir=/data/int8.mp4

But not much speedup . Only 40millisec on the 2080 rtx Ti

We have tried to quantize ppyoloe_crn_l_300e_coco, and it works well on FastDeploy.
Maybe we could help you, how about join our Slack channel for further support? link: https://fastdeployworkspace.slack.com/ssb/redirect

[MyraBaba]

@yunyaoXYY
I will join.

any speed improvement.

[MyraBaba]

@yunyaoXYY did you tried ppyoloe_crn_l_80e_sliced_visdrone_640_025 ? any speedup ?

[MyraBaba]

@yunyaoXYY I need and invitation to join Slack

Inferencing both, an slow.. GPU 10 times CPU 1,5 times
