NBT with some changes to run smoothly with python3

Neural Baby Talk

Setup

To setup requirements, I highly recommend to use virtual environment with conda. Here is the yml file, using this command to complete your package setup.

conda env create -f environment.yml

requirement

Inference:

• pytorch
• torchvision
• torchtext

Data Preparation:

• stanford-corenlp-wrapper
• stanford-corenlp

Evaluation:

• coco-caption: Download the modified version of coco-caption and put it under tools/

Copy model-best.pth and infos_-best.pkl (from save/ dir)to NeuralBabyTalk/

  --cbs_mode CBS_MODE   which cbs mode to use in the decoding stage. cbs_mode:
                        all|unique|novel
  --det_oracle DET_ORACLE
                        whether use oracle bounding box.
  --cnn_backend CNN_BACKEND
                        res101 or vgg16

  --beam_size BEAM_SIZE

NeuralBabyTalk$ python3 demo.py --image_path /home/resl/NeuralBabyTalk/data/coco/images --data_path data/ --cnn_backend res101

Without detection bbox

With detection bbox

Constraint beam search

This code also involve the implementation of constraint beam search proposed by Peter Anderson. I'm not sure my impmentation is 100% correct, but it works well in conjuction with neural baby talk code. You can refer to this paper for more details. To enable CBS while decoding, please set the following flags:

--cbs True|False : Whether use the constraint beam search.
--cbs_tag_size 3 : How many detection bboxes do we want to include in the decoded caption.
--cbs_mode all|unqiue|novel : Do we allow the repetive bounding box? `novel` is an option only for novel object detection task.

Multi-GPU Training

This codebase also support training with multiple GPU. To enable this feature, simply add --mGPUs Ture in the commnad.

Self-Critic Training and Fine-Tuning CNN

This codebase also support self-critic training and fine-tuning CNN. You are welcome to try this part and upload your trained model to the repo!
