Requirements: Software
-
Python 2.7. We recommend using Anaconda. (python 3.x should also be OK.)
-
GLFW for OpenGL:
sudo apt-get install libglfw3-dev libglfw3
(on Ubuntu 16.04) -
Python packages might missing:
conda install scipy pip install Cython pip install opencv-python pip install easydict pip install pyyaml pip install tqdm
glumpy:
pip install pyopengl packaging appdirs pyopengl triangle cython glfw # clone the lastest glumpy (there is a bug in the pip version) git clone https://github.com/glumpy/glumpy.git cd glumpy pip install .
-
MXNet from the official repository.
Option 1: Use the prebuilt version following the installation guide..
nvcc --version pip install mxnet-cu90 # (change to your cuda version)
Option 2. Build MXNet from the source following the official manual:
2.1 Clone MXNet and checkout to MXNet@(commit fc9e70b) by
git clone --recursive https://github.com/dmlc/mxnet.git cd mxnet git checkout fc9e70b (optional) git submodule update (optional)
or use the latest master directly (code is tested under mxnet 1.2.0).
2.2 Compile MXNet
cd ${MXNET_ROOT} make -j $(nproc) USE_OPENCV=1 USE_BLAS=openblas USE_CUDA=1 USE_CUDA_PATH=/usr/local/cuda USE_CUDNN=1
2.3 Install the MXNet Python binding by
Note: If you will actively switch between different versions of MXNet, please follow 2.4
cd python sudo python setup.py install
2.4 For advanced users, you may put your Python packge into
./external/mxnet/$(YOUR_MXNET_PACKAGE)
, and modifyMXNET_VERSION
in./experiments/deepim/cfgs/*.yaml
to$(YOUR_MXNET_PACKAGE)
. Thus you can switch among different versions of MXNet quickly. -
Use tensorboard to visualize loss:
Install mxboard following https://github.com/awslabs/mxboard#installation.
pip install mxboard
Requirements: Hardware
Any NVIDIA GPUs with at least 4GB memory should be OK.
Installation
- Clone the DeepIM repository, and we'll call the directory that you cloned mx-DeepIM as ${DeepIM_ROOT}.
git clone https://github.com/liyi14/mx-DeepIM.git
-
Initialize DeepIM:
2.1 In the root directory of DeepIM, run
sh init.sh
to initialize the DeepIM project. (Note: For python3, need to install pytorch first to jit compile flow_c module.)2.2 (Optional) Delete the data folder and link (i.e.
ln -sf
) the root folder of data to./data
.
Preparation for Training & Testing
-
Prepare datasets, see
./toolkit/
and prepare_data.md for details.The datasets should be put in folder:
./data/
-
Please download FlowNet model manually from Google Drive or Baidu NetDisk (password: shga), and put it under folder
./model
. Make sure it looks like this:./model/pretrained_model/flownet-0000.params
Usage
-
All of our experiment settings (GPU, dataset, etc.) are kept in yaml config files at folder
./experiments/deepim/cfgs
-
To perform experiments, run the python scripts with the corresponding config file as input. For example, to train and test DeepIM models with pre-trained FlowNet, use the following command
python experiments/deepim/deepim_train_test.py --cfg experiments/deepim/cfgs/your_cfg.yaml --gpus 0,1,2,3
A cache folder would be created automatically to save the model and the log under
output/deepim/
. or you can just run the script likesh train_and_test_deepim_ape.sh
to train and test the model only on category ape or run
sh train_and_test_deepim_all.sh
to train and test the model on all categories.
Trained weights for LINEMOD and Occlusion LINEMOD can be found here, Google Drive.
-
Please find more details in config files and in our code.
Misc.
Code has been tested under:
- Ubuntu 14.04/16.04 with 4 GTX 1080Ti GPUs or a single GTX 1070 GPU
