Missing momentum2.mps.gz file

[smoretti]

Hi

I got an error when running python2 setup.py test:

ERROR: Failure: IOError ([Errno 2] No such file or directory: '/builddir/build/BUILD/optlang-1.4.2/slow_tests/data/miplib2003/momentum2.mps.gz')

python2 version 2.7.12

Hi. Thanks for the report. Do you get a longer traceback, or just this line?

[smoretti]

Here is the traceback:

With python 2.7.12 and glpk 4.59 I have also this error during tests (not with python3):

ERROR: Failure: Exception (No optimal solution found for netlib model SIERRA)
----------------------------------------------------------------------
Traceback (most recent call last):

    raise Exception('No optimal solution found for netlib model %s' % netlib_id)
Exception: No optimal solution found for netlib model SIERRA

[KristianJensen]

Thanks. We will look into it. There are currently some problems with our miplib tests, but if all the other tests pass everything should be in order.

If you encounter the missing file error, you can try running the tests with nosetests optlang instead

[smoretti]

OK, thanks nosetests optlang skips the file error test.

Only my "No optimal solution found for netlib model SIERRA" remains

[smoretti]

I have excluded the netlib model SIERRA to skip it, and after that for Python 2 I got errors for the netlib model WOOD1P.

Skipping both let me complete tests successfully.
