I noticed that the fixture for the io tests does not make use of os.path.abspath whereas the tm.get_data_path function does. Perhaps using abspath on the former here could resolve?

pandas/pandas/tests/io/conftest.py

Line 6 in f833103

HERE = os.path.dirname(__file__)

pandas/pandas/util/testing.py

Line 795 in c753e1e

base_dir = os.path.abspath(os.path.dirname(filename))

thank @WillAyd I made that change. Though this is still failing, but only on master. Not really sure what the problem is, but moved this build out of the main matrix for now. Its not very easy to test because it only fails on master and not on a fork. very weird.
