BLIP Image Captioning inside a Docker Container with simple API

Features

• Worker Queue
• Create Image Caption of Image by passing URL

API Endpoints

• /captionImage GET

  • Get job results

• /captionImage POST

  • Post a job to the queue
  • Takes json with imgurls: ['url1', 'url2', ...]
  • When job is done the result will be added to the result list

• /captionImageBlocking POST

  • Post a job to the queue
  • Takes json with "imgurls": ['url1', 'url2', ...]
  • Waits for job to finish and returns the result in the response

Setup/Installation

• I assume that you have docker installed and a CUDA capable GPU
• I suggest that you run everything locally first to verify that every thing works as the docker image build can take quite long
• After running it locally for the first time, there should be a /checkpoints folder with the BLIP model
  • So the docker container can copy it and doesnt need to download it again
