BLD: travis.yml change language to python

[josef-pkt]

try to fix #1502

coverall file access is broken

[josef-pkt]

switching to language python didn't help for coveralls, but the tests ran without problems

[josef-pkt]

The last commit "adjust coverage path" needs to be reverted because it picks up the entire sandbox and lowers our coverage level even further.

I'm giving up on this for now. I have no clue and there are many other repos affected in the same way
(nipy/nipype uses python-coveralls not coveralls)
scipy also doesn't have files for example https://coveralls.io/files/159716513

Can you add

omit = 
    */statsmodels/sandbox*

to the config file and see if that helps for the sandbox issue?

[josef-pkt]

I don't want to exclude the entire sandbox.

The current setting in master actually works pretty well because it ignores all modules that are not run at all during the nosetests. That excludes all the files that are in the sandbox that are currently deadweight, but includes the parts that are in the sandbox because of missing final cleanup and move.
(For example Evgenyi adjusted his changes in scipy.stats.distributions to accommodate my structure of subclasses in the sandbox that have unit tests and failed.)

[jseabold]

Well, if the code is tested, move it out of the sandbox.

[josef-pkt]

my previous comments referred to the unittests itself

But for coverage it's similar, I do check the coverage when I'm working on modules in the sandbox and if there are issues for them. (mutliplecomparison, gmm were the latest cases)

[jseabold]

I assume this is fixed elsewhere now. Close?

[jseabold]

Closing this. Reopen if necessary.
