Cyipopt import error on pyadjoint:latest docker image

libipopt.so.1 cannot be found while importing cyipopt.

Can be tested using poisson-topology.py, which throws an error:

Traceback (most recent call last):
  File "/usr/local/lib/python3.6/dist-packages/pyadjoint/ipopt.py", line 11, in <module>
    import cyipopt  # noqa: F401
ImportError: libipopt.so.1: cannot open shared object file: No such file or directory

During handling of the above exception, another exception occurred:

    solver = IPOPTSolver(problem, parameters=parameters)

    raise ImportError("You need to install cyipopt. It is recommended to install IPOPT with HSL support!")
ImportError: You need to install cyipopt. It is recommended to install IPOPT with HSL support!

Docker command used:

docker run -ti -v $(pwd):/home/fenics/shared quay.io/dolfinadjoint/pyadjoint:latest

try to change “latest” to “master”:

… quay.io/dolfinadjoint/pyadjoint:master

3

it is also reproducible on the “master” image

strangely enough, in the master image, importing ipopt in bash:

$ python3 -c "from pyadjoint import ipopt"

gives another error:

Traceback (most recent call last):
  File "/usr/local/lib/python3.6/dist-packages/pyadjoint/ipopt.py", line 11, in <module>
    import cyipopt  # noqa: F401
ImportError: /usr/local/lib/libipopt.so.1: undefined symbol: MPI_Comm_rank

    raise ImportError("You need to install cyipopt. It is recommended to install IPOPT with HSL support!")
ImportError: You need to install cyipopt. It is recommended to install IPOPT with HSL support!

while giving the same error from the original post when run in PyCharm

Hi Jafar,

I have the same problem when I install it on Ubuntu or Mac systems. Could you fix it? I’ll appreciate it if you can help me to make Ipopt work.

Thanks,
Milad

As far as I can remember, I ran the commands in the Dockerfile as Rafael_Ferro recommended, and it ended up working.

Although now I use Docker and no longer use a local installation. I recommend doing the same for a quick fix.
