ERROR: Could not find a version that satisfies the requirement ctranslate2

Question

I'm learning to use docker and I'm having trouble installing Ctransalte2 inside a docker image. When I run docker build i'm getting the above error. I'm using python:3.8.12 base image which I suspect is the problem. I know Ctranslate2 will only run on Linux/Mac. Do I need to specificity the OS in the base image?

Dockerfile:

FROM python:3.8.12
RUN pip install -r requirements.txt

Answer 1

I highly recommend that start with a simpler task. But For libraries that are popular and under principled maintenance, you can find the official docker container (with a variety of flavors) on docker hub and use them.

docker pull opennmt/ctranslate2

Moreover, if you are in to do it yourself, you can always use official and unofficial GitHub Dockerfile samples to follow, like this one!
