I modified the code from jazzsaxmafia, and I have fixed some problems in his code.

• Tensorflow 0.12
• Keras

$ python extract_feats.py

After this operation, you should split the features into two parts:

• train_features
• test_features

$ CUDA_VISIBLE_DEVICES=0 ipython

When in the ipython environment, then:

>>> import model_rgb
>>> model_rgb.train()

You should change the training parameters and directory path in the model_rgb.py

>>> import model_rgb
>>> model_rgb.test()

After testing, a text file, "S2VT_results.txt" will generated.

We evaluate the generation results with coco-caption tools.

You can run the shell get_coco_tools.sh get download the coco tools:

$ ./get_coco_tools.sh

After this, generate the reference json file from ground truth CSV file:

$ python create_reference.py 

Then, generate the results json file from S2VT_results.txt file:

$ python create_result_json.py

Finally, you can evaluate the generation results:

$ python eval.py

1. Please feel free to ask me if you have questions.
2. I only commit the RGB parts of all my code, you can modify the code to use optical flow features.
