Update: Michael fixed it for me. Apparently it was because I tried to update through pip although I've installed kwant and tinyarray with homebrew.  Michael might already change it, but with the current Homebrew formulas tinyarray 1.0.2 is installed.  Best, Bas On Fri, Jan 30, 2015 at 3:29 PM, Bas Nijholt <basnijholt@gmail.com> wrote:
