Environment setup

This code has been tested on Ubuntu 16.04, Python 3.6, Pytorch=0.4.1, CUDA 9.2, GTX 1080Ti, Titan X, and RTX Titan GPUs.

Warning: the results can be slightly different due to Pytorch version and CUDA version.

• Clone the repository

git clone git@gitlab.inria.fr:yixu/deepmot.git && cd deepmot

Option 1:

• Follow the installation instructions in Tracktor.

Option 2 (recommended):

we provide a Singularity image with all packages pre-installed (similar to Docker) for training and testing.

• Open a terminal
• Install Singularity > 3.0 package: https://sylabs.io/guides/3.3/user-guide/installation.html#install-on-linux
• Download the Singularity image: tracker.sif (google drive) or tracker.sif (tencent cloud)
• Open a new terminal
• Launch a Singularity image

singularity shell --nv --bind yourLocalPath:yourPathInsideImage tracker.sif

- -bind: to link a singularity path with a local path. By doing this, you can find data from local PC inside Singularity image; - -nv: use the local Nvidia driver.

Testing

• Setup your environment

• Go to the test_tracktor folder

• Download MOT data Dataset can be downloaded here: MOT17Det, MOT16Labels, MOT16-det-dpm-raw and MOT17Labels . 2. Unzip all the data by executing:

  unzip -d MOT17Det MOT17Det.zip
  unzip -d MOT16Labels MOT16Labels.zip
  unzip -d 2DMOT2015 2DMOT2015.zip
  unzip -d MOT16-det-dpm-raw MOT16-det-dpm-raw.zip
  unzip -d MOT17Labels MOT17Labels.zip
  

• Enter the data path to data_pth in the test_tracktor/experiments/cfgs/tracktor_pub_reid.yaml and test_tracktor/experiments/cfgs/tracktor_private.yaml

• Download pretrained models all the pretrained models can be downloaded here: deepMOT-Tracktor.pth (google drive) or deepMOT-Tracktor.pth (tencent cloud)

• Enter the model path to parameter obj_detect_weights in the test_tracktor/experiments/cfgs/tracktor_pub_reid.yaml and test_tracktor/experiments/cfgs/tracktor_private.yaml

• Set the dataset name in the test_tracktor/experiments/cfgs/tracktor_pub_reid.yaml and test_tracktor/experiments/cfgs/tracktor_private.yaml: For MOT17 (by default):

dataset: mot17_train_17

For MOT16 (images as the same as MOT17):

dataset: mot17_all_DPM_RAW16

• run tracking code

python test_tracktor/experiments/scripts/tst_tracktor_private.pytst_tracktor_pub_reid.py (public detections) or test_tracktor/experiments/scripts/tst_tracktor_private.py (private detections)

The results are saved by default under test_tracktor/output/log/, you can modify it by changing output_dir in the test_tracktor/experiments/cfgs/tracktor_pub_reid.yaml and test_tracktor/experiments/cfgs/tracktor_private.yaml.

• Visualization: You can set write_images: True in the test_tracktor/experiments/cfgs/tracktor_pub_reid.yaml and test_tracktor/experiments/cfgs/tracktor_private.yaml to plot and save images. By default, they will be saved inside test_tracktor/output/log/ if write_images: True.

Training

• Setup your environment

• Go to the train_tracktor folder

• Download MOT Dataset can be downloaded here: MOT17Det, MOT16Labels, MOT16-det-dpm-raw and MOT17Labels.

• Unzip all the data by executing:

  unzip -d MOT17Det MOT17Det.zip
  unzip -d MOT16Labels MOT16Labels.zip
  unzip -d 2DMOT2015 2DMOT2015.zip
  unzip -d MOT16-det-dpm-raw MOT16-det-dpm-raw.zip
  unzip -d MOT17Labels MOT17Labels.zip
  

• Enter the data path to data_pth in the train_tracktor/experiments/cfgs/tracktor_full.yaml

• Download the output folder containing the configurations and the model to be fine-tuned and DHN pre-trained model: output.zip (google drive) or output.zip (tencent cloud)

• unzip the "output" folder and put it to train_tracktor.

• run training code

python train_tracktor/experiments/scripts/train_tracktor_full.py

The trained models are saved by default under train_tracktor/output/log_full/ folder. The tensorboard logs are saved by default under deepmot/logs/train_log/ folder and you can visualize your training process by:

tensorboard --logdir=YourGitFolder/train_tracktor/output/log_full/

Note:

• you should install tensorflow (see tensorflow installation) in order to visualize your training process.

pip install --upgrade tensorflow

Train DHN

• Download the traindata (distance and ground-truth matrices calculated from MOT datasets): DHN data (google drive) or DHN data (tencent cloud)

• unzip DHN_data and put the DHN_data folder to train_DHN/

• Run:

python train_DHN/train_DHN.py --is_cuda --bidirectional

for more parameter details please run:

python train_DHN/train_DHN.py -h

By default the trained models are saved into train_DHN/output/DHN/ and log files in train_DHN/log/

your can visualize the training via tensorboard:

tensorboard --logdir=YourGitFolder/train_DHN/log/

Note:

• you should install tensorflow (see tensorflow installation) in order to visualize your training process.

pip install --upgrade tensorflow

Evaluation

You can run test_tracktor/experiments/scripts/evaluate.py to evaluate your tracker's performance.

• fill the list predt_pth in the code with the folder where the results (.txt files) are saved.
• make sure the data path is correctly set.
• then run

python test_tracktor/experiments/scripts/evaluate.py
