cylp-docker's Issues

Can't import CYLP

I'm trying to pull the docker image and then run the sample problem for the docs.

Steps to reproduce:

Dockerfile:

FROM coinor/cylp
RUN apt-get update 

COPY mwe.py ./
RUN python3 mwe.py

mwe.py

from CyLP.cy import CyClpSimplex
s = CyClpSimplex()
s.readMps('../input/netlib/adlittle.mps')
s.initialSolve()

Build with docker build .

Expected behavior

Docker builds sucessfully, which includes running mwe.py, which solves a sample problem.

Actual behavior

Docker build fails.

Step 5/11 : RUN python3 mwe.py
 ---> Running in 2e683a4a1f37
Traceback (most recent call last):
  File "mwe.py", line 1, in <module>
    from CyLP.cy import CyClpSimplex
ModuleNotFoundError: No module named 'CyLP'
The command '/bin/sh -c python3 mwe.py' returned a non-zero code: 1

If I change the case to cylp (different to the docs) then I get a different import error:

Traceback (most recent call last):
  File "<stdin>", line 1, in <module>
  File "/var/cbc/CyLP/cylp/cy/__init__.py", line 1, in <module>
    from .CyCoinIndexedVector import CyCoinIndexedVector
ModuleNotFoundError: No module named 'cylp.cy.CyCoinIndexedVector'

Can you please show what the contents of myscript.py was in the example, so I can see how it differs from the cylp example?
