Web25 nov. 2010 · This NEP proposes to replace the NumPy iterator and multi-iterator with a single new iterator, designed to be more flexible and allow for more cache-friendly data access. The new iterator also subsumes much of the core ufunc functionality, making it easy to get the current ufunc benefits in contexts which don’t precisely fit the ufunc mold. WebAnother stability issue is due to the internal implementation of numpy.arange . The actual step value used to populate the array is dtype (start + step) - dtype (start) and not step.
