?516 Error: Problem has not been loaded

Hello community,

I'm using the python API xpress and trying to load a .lp file; (m = xp.problem () , m.read("file")) ;

The file is around 2 GB and i cannot load it; Is there any size limitation in the python api?

I can read it into the solver from command prompt but just not from python. Appreciate any advice!

Thank you!

Mark

    Hi Mark,

    there is no size limitation in the Python API if you have the full license. If it is not a license issue, I think it's because loading a problem into memory using Python uses a little more memory than with the command prompt, because of a few extra data structures. This might use up all your memory. Can you tell how much memory is available before reading the problem?

    Thanks,

    Pietro
