How to change the default solver cplex to gurobi？

[wupeng1998]

I have some problems when using cplex. How can I change the default solver of carveme to gurobi?

You can now do this in the latest version (1.5.2). Just use --solver gurobi :)

I am having issues setting gurobi as my solver. This is my input; carve --dna genomic.fna --init M9 --solver gurobi --fbc2 -o carved_model.xml Which produces the following error:

Traceback (most recent call last):
  File "C:\Users\mol131\Anaconda3\lib\runpy.py", line 197, in _run_module_as_main
    return _run_code(code, main_globals, None,
  File "C:\Users\mol131\Anaconda3\lib\runpy.py", line 87, in _run_code
    exec(code, run_globals)

    raise RuntimeError(f"Solver {solvername} not available.")
RuntimeError: Solver cplex not available.

Thanks for your help

Hey @jmol0917,

I found the same error, I think due to a single uncommented line. See this issue
