The numpy boolean negative, the `-` operator, is not supported, use the `~` operator or the logical_not function instead #46

With numpy == 1.13.0 the tests break, though the same build used to pass (this numpy version was recently released). The error message below suggests as a possible replacement using the function logical_not.
