Some machines including mine were having float rounding issues when translating some gates (the state phase was equal to 1 + 1e-18j which was not equal to 1)
This PR replaces the array_equal function by allclose, using the default thresholds to ensure this comparison will work even with float issues. It also improves the Makefile to detect if
python3
is an available command on the users machine to use it instead.Safe to revert.
