1. Use a Linux distribution. We have been developed and tested the code on Ubuntu.

2. Requirements for Caffe and pycaffe (see: Caffe installation instructions).

Note: Caffe must be built with support for Python layers!

# In your Makefile.config, make sure to have this line uncommented
WITH_PYTHON_LAYER := 1

3. Python packages you might not have: cython, python-opencv, easydict, opencv.

This code allows the usage of CPU and GPU. We strongly recommend the usage the GPU due it is going to short the training and testing time by a factor of 10 or so.

1. For training, we recommend having a GPU with at least 3GB of memory.

2. For testing, a GPU with 2GB memory is enough.

1. Be sure you have added to your PATH the tools directory of your Caffe compilation:

   export PATH=$CAFFE_ROOT/build/tools:$PATH

2. Be sure you have added your pycaffe compilation into your PYTHONPATH:

   export PYTHONPATH=$CAFFE_ROOT/python:$PYTHONPATH

3. Download the TRANCOS dataset by executing the following command:

   ./tools/get_trancos.sh

4. Download the TRANCOS CCNN model. Comming soon

After successfully completing basic installation, you'll be ready to run the demo.

```
./tools/demo.sh
```

To train an test your own model, you should follow the next steps:

1. Edit the configuration file "ccnn_trancos_cfg.yml" placed into the corresponding model folder (e.g.: $PROJECT/models/trancos/ccnn).

2. Edit the launching script (e.g.: $PROJECT/experiments/scripts/trancos_train_test.sh):

3. Place you in $PROJECT folder and run the launching script by typing:

   ./experiments/scripts/trancos_train_test.sh

Comming soon...

In order to download and setup a dataset we recommend to use our scripts. To do so, just place you in the $PROJECT directory and run one of the following commands:

• TRANCOS dataset:

   ./tools/get_trancos.sh

• UCSD dataset:

   ./tools/get_ucsd.sh

• UCF dataset:

   ./tools/get_ucf.sh

Note: Make sure the folder "data/" does not already contain the dataset.

In order to provide a better distribution, this repository unifies and reimplement in Python some of the original modules. Due the changes in the libraries, the results produced by the pretrained models may have been slightly changed with respect to the numbers provided in the paper.
