Containerize AllenNLP model

Hi, I need a simple Dockerfile fixed that builds a container running a FastAPI server that initialises an AllenNLP model. I'm including my own Dockerfile, requirements.txt and main.py which don't work at the moment because when the container starts, it begins downloading something (a dependency?) which then crashes the server because of timeouts. The main.py file works fine when I run it locally. Please help me sort this out!

N.B. The folder "coref-data" that is copied into the container just contains the package from here:
https://storage.googleapis.com/allennlp-public-models/coref-spanbert-large-2021.03.10.tar.gz
