I'm trying to use the CPLEX library alongside Qiskit but keep getting the error.
File "C:\Users\charl\.conda\envs\quantum\lib\site-packages\qiskit\optimization\algorithms\cplex_optimizer.py", line 58, in __init__ raise MissingOptionalLibraryError( qiskit.aqua.missing_optional_library_error.MissingOptionalLibraryError: "The 'CPLEX' library is required to use 'CplexOptimizer'. You can install it with 'pip install qiskit-aqua[cplex]'."
Now when of course run that command, I find that all these packages are already installed.
When I tried manually updating docplex, I got a warning saying the latest version was incompatible with qiskit and so I downgraded using pip to docplex 2.15.194, yet I still get the error.
What can I do to get docplex and Qiskit to talk to one another ?
I am using a windows 10 installation of qiskit in a conda environment.
