Control: retitle -1 pandas: several CI tests fail This isn't the only problem:
-test_set_locale: this one passes when I run it manually, which vaguely suggests a missing dependency, but I don't know which one.
-test_binary_ops, test_mixed_arithmetic*: "Integers to negative integer powers are not allowed" due to a numpy change in 1.12. Known upstream as https://github.com/pandas-dev/pandas/issues/15363, where the workaround is to skip the 'pow' part of these tests.
-test_integer_panel (Python 2 only): integer overflow in the 'pow' test.
