Mosek install error #1500

Closed mjburton11 closed 4 years ago

mjburton11 commented 4 years ago

Running with Anaconda2, Python 3.7, Mosek 8 (although I also saw this issue when running with Mosek 9) on someone else's machine. Got this error:

When I run python python -c "from gpkit.build import build; build()" it looks good so I'm surprised that this is not working

python 3 doesn't support mosek, unfortunately. i should add a version print to that build message, but this should build fine on a newer version.

the reason it works with the second command is that it's building but not running the tests

Wow that's really sad. Do you think they will ever update?

bqpd commented 4 years ago

Well, more accurately I tested mosek_cli's speed and found it to be just as good as mosek and so didn't bother building out the C-bindings like for Python2 (especially in anticipation of mosek9, though that's still a little slower)

whoburg commented 4 years ago

This seems like a common source of confusion. Would it be worth discussing implementing .solve('mosek') such that it just calls .solve('mosek_cli') so that this is more seamless for users? Or is there a disadvantage to changing the meaning of an existing argument value, 'mosek'?

bqpd commented 4 years ago

it's a problem with an old version of GPkit unfortunately; new updates won't fix it!

bqpd commented 4 years ago
whoburg commented 4 years ago

gotcha

mjburton11 commented 4 years ago

ok so so I'm still confused here. mosek doesn't work with python 3 but mosek_cli does? and does gpkit still support python 2.7?

What are the optimum settings here: python 2.7 or 3? gpkit dev? mosek 9 or 8?

bqpd commented 4 years ago

v0.9.9 is the last one to support Python2.7 and the mosek C-bindings interface for mosek 7/8

the current dev branch does not support either of those :-/

both v0.9.9 and the current dev branch support Python3, mosek 7/8 via the mosek_cli interface and mosek 9 via the mosek_conif interface
