YoloP

The original pytorch model is from hustvl/YOLOP

Authors

1. Prepare building environments

Make sure you have install c++(support c++11)、 cmake、opencv(4.x)、cuda(10.x)、nvinfer(7.x).

2. build yolop

Go to yolop.

mkdir build
cd build

cmake ..
make

Now you can get yolop and libmyplugins.so.

3. Test in C++

Go to yolop/build.

3.1 generate yolop.wts

Download/Clone YOLOP

Edit gen_wts.py , change YOLOP_BASE_DIR to realpath of YOLOP.

# [WARN] Please download/clone YOLOP, then set YOLOP_BASE_DIR to the root of YOLOP
python3 ../gen_wts.py

3.2 generate yolop.trt

./yolop -s yolop.wts  yolop.trt

Now you have such files: libmyplugins.so yolop yolop.wts yolop.trt

3.3 test yolop.trt

mkdir ../results

YOLOP_BASE_DIR=/home/user/jetson/tmp/YOLOP
./yolop -d yolop.trt  $YOLOP_BASE_DIR/inference/images/

It will output like as follow if successful! ( test on Jetson Xavier NX - Jetpack 4.4)

1601ms # the fist time is slow
26ms   # then it is faster
29ms
27ms
29ms
29ms

4. Test in python3

Go to yolop.

Make sure you have install pycuda tensorrt; and modify image_dir to your image dir.

# usage: xxx <engine file> <plugin file> <image dir>

python3 yolop_trt.py  build/yolop.trt  build/libmyplugins.so /home/user/jetson/tmp/YOLOP/inference/images

It will output like as follow if successful! ( test on Jetson Xavier NX - Jetpack 4.4)

usage: xxx <engine file> <plugin file> <image dir>

done!

Notice : The results of c++ and python are not aligned for now!
