[Numpy-discussion] Re: Function that searches arrays for the first element that satisfies a condition

This results in a very slow code. The function calls of _pred = numba.njit(pred) are expensive and this sort of approach will be comparable to pure python functions. This is only recommended for sourcing functions that are not called frequently, but rather have a large computational content wit

[Numpy-discussion] Re: Function that searches arrays for the first element that satisfies a condition

Could a sub-python level spin up extra threads (processes)? Search could benefit easily. I switched back to Java for number crunching because one gets to share memory without using OS-supplied shared memory. Maybe put a JVM behind python, or do python in the JVM? Bill -- Phobrain.com On 202

If you add a layer of indirection with Numba you can get a *very* nice API: @numba.njit def _first(arr, pred): for i, elem in enumerate(arr): if pred(elem): return i def first(arr, pred): _pred = numba.njit(pred) return _first(arr, _pred) This even works with lamb

[Numpy-discussion] Re: Function that searches arrays for the first element that satisfies a condition

I've implemented such functions in Cython and packaged them into a library called numpy_illustrated It exposes the following functions: find(a, v) # returns the index of the first occurrence of v in a first_above(a, v) # returns the index of the fi
