Hello,
Is "b" an expected value? I am suspecting another floating point arithmetic issue.
I[1]: a = np.arange(1.6, 1.8, 0.1, dtype='float32')
I[2]: a O[2]: array([ 1.60000002, 1.70000005], dtype=float32)
I[3]: b = np.arange(1.7, 1.8, 0.1, dtype='float32')
I[4]: b O[4]: array([ 1.70000005, 1.79999995], dtype=float32)
A bit conflicting with the np.arange docstring:
" Values are generated within the half-open interval ``[start, stop)`` (in other words, the interval including `start` but excluding `stop`). "
Try np.linspace(). It works better with floats:
np.linspace(1.7, 1.8, 2)
array([ 1.7, 1.8])
