carveme 1.5 not finding cplex #121

Closed vrmarcelino closed 3 years ago

vrmarcelino commented 3 years ago

Hi Daniel,

I have updated carveme to version 1.5.0 and I am now getting the error: RuntimeError: Solver cplex not available.

I am using carveme within a conda environment, and I have re-installed the cplex Python API. When I run python -c 'import cplex', I get no message, so I think the API is installed correctly. But when I run python -c 'from cplex import Cplex, I get:

ImportError: cannot import name 'Cplex' from 'cplex' (unknown location) Any ideas of what might be going on?

Thanks!

That's strange, I haven't seen that one before.

Can you also run:

python -c 'import cplex; print(cplex.__version__)'

and:

python -c 'import cplex; print(dir(cplex))'

Hi!

I think the problem is that we have multiple python versions (and environments) in our server.

The first one returned an error (in the conda env):

Traceback (most recent call last):
  File "<string>", line 1, in <module>
AttributeError: module 'cplex' has no attribute '__version__'

And dir(cplex) only returned: ['__doc__', '__file__', '__loader__', '__name__', '__package__', '__path__', '__spec__']

But running the same commands using my default python returned the cplex version 20.1.0.0 and a lot more things under the dir(cplex) command.

So I just re-installed carveme outside of a conda env, and it works! =)

Thank you!!
