Gpu support in CLI needed

[dPeS]

Hi,

When I added --gpus option here [1]:

cs submit --executor mesos --gpus 1 sleep 10
works ok (task is finished on gpu host), but:

[centos@ip-192-168-1-20]$ sudo cs submit --executor mesos --gpus 0 sleep 1
Attempting to submit on KKK cluster...
Job submission failed on KKK:
{"jobs": [{"gpus": "(not (pos? 0))"}]}
Job submission failed on all of your configured clusters.

any clues?

Hey @dPeS, thanks for the issue. The error you're getting is due to the fact that we have a server-side schema validation that doesn't allow gpus to be non-positive:

https://github.com/twosigma/Cook/blob/master/scheduler/src/cook/mesos/api.clj#L250

Can you leave off the --gpus flag altogether for the case where you don't need gpus?

Hi Daniel,

Sure I'm good here - that doesn't block me - just reporting.
Please remember to add --gpus option to submit.py

Sounds good. I will take a look at this. Glad to hear you're not blocked.

@dposada thanks, so I'm good here!
