Error building build_extend_utils_cffi.py

Good news! We release a clean version of PVNet: clean-pvnet, including

how to train the PVNet on the custom dataset.
Use PVNet with a detector.
The training and testing on the tless dataset, where we detect multiple instances in an image.

Truncation LINEMOD Dataset

Check TRUNCATION_LINEMOD.md for information about the Truncation LINEMOD dataset.

Installation

One way is to set up the environment with docker: How to install pvnet with docker.

Thanks Joe Dinius for providing the docker implementation.

Another way is to use the following commands.

Set up python 3.6.7 environment

pip install -r requirements.txt

We need compile several files, which works fine with pytorch v0.4.1/v1.1 and gcc 5.4.0.

For users with a RTX GPU, you must use CUDA10 and pytorch v1.1 built from CUDA10.

Compile the Ransac Voting Layer

ROOT=/path/to/pvnet
cd $ROOT/lib/ransac_voting_gpu_layer
python setup.py build_ext --inplace

Compile some extension utils

cd $ROOT/lib/utils/extend_utils

Revise the cuda_include and dart in build_extend_utils_cffi.py to be compatible with the CUDA in your computer.

sudo apt-get install libgoogle-glog-dev=0.3.4-0.1
sudo apt-get install libsuitesparse-dev=1:4.4.6-1
sudo apt-get install libatlas-base-dev=3.10.2-9
python build_extend_utils_cffi.py

If you cannot install libsuitesparse-dev=1:4.4.6-1, please install libsuitesparse, run build_ceres.sh and move ceres/ceres-solver/build/lib/libceres.so* to lib/utils/extend_utils/lib.

Add the lib under extend_utils to the LD_LIBRARY_PATH

export LD_LIBRARY_PATH=$LD_LIBRARY_PATH:/path/to/pvnet/lib/utils/extend_utils/lib

Dataset Configuration

Prepare the dataset

Download the LINEMOD, which can be found at here.

Download the LINEMOD_ORIG, which can be found at here.

Download the OCCLUSION_LINEMOD, which can be found at here.

Create the soft link

mkdir $ROOT/data
ln -s path/to/LINEMOD $ROOT/data/LINEMOD
ln -s path/to/LINEMOD_ORIG $ROOT/data/LINEMOD_ORIG
ln -s path/to/OCCLUSION_LINEMOD $ROOT/data/OCCLUSION_LINEMOD

Compute FPS keypoints

python lib/utils/data_utils.py

Synthesize images for each object

See pvnet-rendering for information about the image synthesis.

Demo

Download the pretrained model of cat from here and put it to $ROOT/data/model/cat_demo/199.pth.

Run the demo

python tools/demo.py

If setup correctly, the output will look like

Visualization of the voting procedure

We add a jupyter notebook visualization.ipynb for the keypoint detection pipeline of PVNet, aiming to make it easier for readers to understand our paper. Thanks for Kudlur, M 's suggestion.

Training and testing

Training on the LINEMOD

Before training, remember to add the lib under extend_utils to the LD_LIDBRARY_PATH

export LD_LIDBRARY_PATH=$LD_LIDBRARY_PATH:/path/to/pvnet/lib/utils/extend_utils/lib

Training

python tools/train_linemod.py --cfg_file configs/linemod_train.json --linemod_cls cat

Testing

We provide the pretrained models of each object, which can be found at here.

Download the pretrained model and move it to $ROOT/data/model/{cls}_linemod_train/199.pth. For instance

mkdir $ROOT/data/model
mv ape_199.pth $ROOT/data/model/ape_linemod_train/199.pth

Testing

python tools/train_linemod.py --cfg_file configs/linemod_train.json --linemod_cls cat --test_model
