Image captioning with Visual Attention
This project follows this Tensorflow 2 tutorial. Instead of training on small dataset like in the tutorial, I train on whole MS-COCO-2014 dataset.
Setup
Environment tool: conda
In file environment.yml:
- Remember to change
/home/anhvd/miniconda3/envs/imgcapcorresponding to your OS and username. - Check YOUR gpu's cudatoolkit and cudnn. You might need to change these:
cudatoolkit=10.1.243=h6bb024c_0cudnn=7.6.5=cuda10.1_0
Cmds:
conda env create -f environment.yml
Or you can just create new environment with this cmd:
conda create -n imgcap python=3.6 tensorflow-gpu cudatoolkit=<version> cudnn=<version>
Training
This model is trained on a single Tesla K80 12 GiB about 10 hours.
Step 1: run this python download_extract.py. It will download, prepare MS-COCO-2014 dataset; then tokenize, extract feature.
Step 2: run this python train.py. It will train model and save it.
Inference
Download pretrained_models.zip from this repos' latest release section. This file zip provides:
annotations/captions_train2014.jsonfrom MS-COCO-2014 dataset- my checkpoints folder ~ pretrained models
Open file inf.py then scroll down to this block of code, then edit image_file, possibly annotation_file and checkpoint_path. Then run with python inf.py
if '__main__' == __name__:
image_file = 'surf.jpg'
annotation_file='./annotations/captions_train2014.json'
checkpoint_path='./checkpoints/train/'
ts = time.time()
feature_extractor = FeatureExtraction.build_model_InceptionV3()
tokenizer, max_length = load_tokenizer(annotation_file)
encoder, decoder = load_latest_imgcap(checkpoint_path)
te = time.time()
load_model_time = te - ts
models = [feature_extractor,
tokenizer, max_length,
encoder, decoder]
ts = time.time()
print(inference(image_file, models))
te = time.time()
inference_time = te - ts
print(f'Loading models takes {load_model_time} seconds')
print(f'Inference takes {inference_time} seconds')CPU that I used:
