Dockerfile: pip install fails with requirements.txt (but succeeds with individual packages)

Question

I'm trying to install some packages in a docker container, and there is a problem when installing from a requirements.txt file. This line:

RUN python3.8 -m pip install -r requirements.txt

fails with the error:

...

The requirements.txt file is the following:

numpy
opencv-python
torch

However, when installing these packages one at a time everything works fine:

RUN python3.8 -m pip install numpy
RUN python3.8 -m pip install opencv-python
RUN python3.8 -m pip install torch

Any ideas how to solve this?

*** EDIT ***

Dockerfile up to that point:

FROM public.ecr.aws/lambda/python:3.8
COPY requirements.txt ./

What base image are you using? Could you share your Dockerfile up to this command? — Chiel, Mar 22 '21 at 08:56

You could try a couple of things. Depending on your base image, you could run pip install in this way:

RUN pip install -r requirements.txt

Another option would be to change your requirements.txt such that it is version controlled. Then you can be sure you have compatible versions and is a good practice in general. Eg.:

torch==1.8.0

Try to run Docker again with without caches, you can use the --no-cache flag:

docker build --no-cache .

Or you could check this answer:
