Overview

Ultra_Fast_Lane_Detection_TensorRT

An ultra fast tiny model for lane detection, using onnx_parser, TensorRTAPI to accelerate. our model support for int8, dynamic input and profiling. (Nvidia-Alibaba-TensoRT-hackathon2021)
这是一个基于TensorRT加速UFLD的repo,包含PyThon ONNX Parser以及C++ TensorRT API版本, 还包括Torch2TRT版本, 对源码和论文感兴趣的请参见:https://github.com/cfzd/Ultra-Fast-Lane-Detection

一. PyThon ONNX Parser

1. How to run

1) pip install -r requirements.txt

2) TensorRT7.x wil be fine, and other version may got some errors

2) For PyTorch, you can also try another version like 1.6, 1.5 or 1.4

2. Build ONNX(将训练好的pth/pt模型转换为onnx)

1) static(生成静态onnx模型):
python3 torch2onnx.py onnx_dynamic_int8/configs/tusimple_4.py --test_model ./tusimple_18.pth 

2) dynamic(生成支持动态输入的onnx模型):
First: vim torch2onnx.py
second: change "fix" from "True" to "False"
python3 torch2onnx.py onnx_dynamic_int8/configs/tusimple_4.py --test_model ./tusimple_18.pth

3. Build trt engine(将onnx模型转换为TensorRT的推理引擎)

We support many different types of engine export, such as static fp32, fp16, dynamic fp32, fp16, and int8 quantization
我们支持多种不同类型engine的导出,例如:静态fp32、fp16,动态fp32、fp16,以及int8的量化

static(fp32, fp16): 对于静态模型的导出,终端输入:

fp32:
python3 build_engine.py --onnx_path model_static.onnx --mode fp32<br/>
fp16:
python3 build_engine.py --onnx_path model_static.onnx --mode fp16<br/>

dynamic(fp32, fp16): 对于动态模型的导出,终端输入:

fp32:
python3 build_engine.py --onnx_path model_dynamic.onnx --mode fp32 --dynamic
fp16:
python3 build_engine.py --onnx_path model_dynamic.onnx --mode fp16 --dynamic

int8 quantization 如果想使用int8量化,终端输入:

python3 build_engine.py --onnx_path model_static.onnx --mode int8 --int8_data_path data/testset1000
# (int8_data_Path represents the calibration dataset)
# (其中int8_data_path表示校正数据集)

4. evaluate(compare)

(If you want to compare the acceleration and accuracy of reasoning through TRT with using pytorch, you can run the script)
(如果您想要比较通过TRT推理后,相对于使用PyTorch的加速以及精确度情况,可以运行该脚本)

python3 evaluate.py --pth_path PATH_OF_PTH_MODEL --trt_path PATH_OF_TRT_MODEL

二. torch2trt

torch2trt is an easy tool to convert pytorch model to tensorrt, you can check model details here:
https://github.com/NVIDIA-AI-IOT/torch2trt
(torch2trt 是一个易于使用的PyTorch到TensorRT转换器)

How to run

1) git clone https://github.com/NVIDIA-AI-IOT/torch2trt

2) python setup.py install

2) PyTorch >= 1.6 (other versions may got some errors)

生成trt模型

python3 export_trt.py

torch2trt 预测demo (可视化)

python3 demo_torch2trt.py --trt_path PATH_OF_TRT_MODEL --data_path PATH_OF_YOUR_IMG

evaluated

python3 evaluate.py --pth_path PATH_OF_PTH_MODEL --trt_path PATH_OF_TRT_MODEL --data_path PATH_OF_YOUR_IMG --torch2trt

三. C++ TensorRT API

生成权重文件

python3 export_trtcy.py

trt模型生成

修改第十行为 #define USE_FP32,则为FP32模式, 修改第十行为 #define USE_FP16,则为FP16模式

mkdir build
cd build
cmake ..
make
./lane_det -transfer             //  'lane_det.engine'

Tensorrt预测

./lane_det -infer  ../imgs 

四. trtexec

test tensorrt_dynamic_model on terminal, for instance, for batch_size=BATCH_SIZE, just run:

trtexec  --explicitBatch --minShapes=1x3x288x800 --optShapes=1x3x288x800 --maxShapes=32x3x288x800 --shapes=BATCH_SIZEx3x288x800 --loadEngine=lane_fp32_dynamic.trt --noDataTransfers --dumpProfile --separateProfileRun

    请问怎么用CULane数据集训练的权重来推理

    我使用UFLD_C++来进行推理,修改了export_trtcy.py中的model = parsingNet(pretrained=False, backbone='18', cls_dim=(101, 56, 4), use_aux=False).cuda(),改为model = parsingNet(pretrained=False, backbone='18', cls_dim=(201, 18, 4), use_aux=False).cuda(),并且把OUTPUT_C改成201,把OUTPUT_H改成18,把OUTPUT_W改为4. 然后运行./lane_det -transfer的时候抛出了下面的错误: ./lane_det -transfer Loading weights: ../lane_culane.trtcy Platform supports fp16 mode and use it !!!

  • Unpickling issue with torch2trt

    Unpickling issue with torch2trt

    I converted the tusimple_18.pth weight from the original UFLD repo using torch2onnx.py and build_engine.py scripts to a trt file. Running evaluate.py shows Inference time with PyTorch = 141.777 ms and Inference time with TensorRT_static = 27.395 ms in fp16. However, running UFLD_torch2trt/demo_torch2trt.py returns this error: Traceback (most recent call last): File "UFLD_torch2trt/demo_torch2trt.py", line 96, in <module> demo_with_torch2trt(trt_path, data_path) File "UFLD_torch2trt/demo_torch2trt.py", line 31, in demo_with_torch2trt model_trt.load_state_dict(torch.load(trt_file_path)) File "/home/nam/.local/lib/python3.6/site-packages/torch/serialization.py", line 593, in load return _legacy_load(opened_file, map_location, pickle_module, **pickle_load_args) File "/home/nam/.local/lib/python3.6/site-packages/torch/serialization.py", line 762, in _legacy_load magic_number = pickle_module.load(f, **pickle_load_args) _pickle.UnpicklingError: unpickling stack underflow It appears the issue mostly comes from loading old torchvision models, I tried to delete torch caches but it didnt work. I tried for both static and dynamic model but the result is the same. :(
