The Interaction: However SciPy and NumPy Activity Unneurotic
The powerfulness of SciPy lies successful its seamless integration with NumPy. SciPy features frequently judge NumPy arrays arsenic enter and instrument NumPy arrays arsenic output. This choky coupling permits builders to leverage the strengths of some libraries. For illustration, you mightiness usage NumPy to burden and pre-procedure information, past walk the ensuing array to a SciPy relation for additional investigation oregon optimization.
This symbiotic relation is cardinal to the Python technological computing ecosystem, fostering businesslike and concise codification. Arsenic an illustration, see performing linear regression. You would usage NumPy arrays to shop the information factors and past make the most of SciPy’s linregress relation to cipher the regression parameters.
For case, a information person mightiness usage NumPy to cleanable and format a ample dataset, past leverage SciPy’s statistical capabilities to execute proposal investigating oregon physique predictive fashions. Larn much astir maximizing your outcomes with NumPy.

Question & Answer :
SciPy seems to supply about (however not each [1]) of NumPy’s features successful its ain namespace. Successful another phrases, if location’s a relation named numpy.foo, location’s about surely a scipy.foo. About of the clip, the 2 look to beryllium precisely the aforesaid, oftentimes equal pointing to the aforesaid relation entity.
Generally, they’re antithetic. To springiness an illustration that got here ahead late:
numpy.log10is a ufunc that returns NaNs for antagonistic arguments;scipy.log10returns analyzable values for antagonistic arguments and doesn’t look to beryllium a ufunc.
The aforesaid tin beryllium mentioned astir log, log2 and logn, however not astir log1p [2].
Connected the another manus, numpy.exp and scipy.exp look to beryllium antithetic names for the aforesaid ufunc. This is besides actual of scipy.log1p and numpy.log1p.
Different illustration is numpy.linalg.lick vs scipy.linalg.lick. They’re akin, however the second affords any further options complete the erstwhile.
Wherefore the evident duplication? If this is meant to beryllium a wholesale import of numpy into the scipy namespace, wherefore the delicate variations successful behaviour and the lacking features? Is location any overarching logic that would aid broad ahead the disorder?
[1] numpy.min, numpy.max, numpy.abs and a fewer others person nary counter tops successful the scipy namespace.
[2] Examined utilizing NumPy 1.5.1 and SciPy zero.9.0rc2.
Past clip I checked it, the scipy __init__ methodology executes a
from numpy import *
truthful that the entire numpy namespace is included into scipy once the scipy module is imported.
The log10 behaviour you are describing is absorbing, due to the fact that some variations are coming from numpy. 1 is a ufunc, the another is a numpy.lib relation. Wherefore scipy is preferring the room relation complete the ufunc, I don’t cognize disconnected the apical of my caput.
EDIT: Successful information, I tin reply the log10 motion. Trying successful the scipy __init__ technique I seat this:
# Import numpy symbols to scipy sanction abstraction import numpy arsenic _num from numpy import oldnumeric from numpy import * from numpy.random import rand, randn from numpy.fft import fft, ifft from numpy.lib.scimath import *
The log10 relation you acquire successful scipy comes from numpy.lib.scimath. Wanting astatine that codification, it says:
""" Wrapper features to much person-affable calling of definite mathematics features whose output information-kind is antithetic than the enter information-kind successful definite domains of the enter. For illustration, for capabilities similar log() with subdivision cuts, the variations successful this module supply the mathematically legitimate solutions successful the analyzable flat: >>> import mathematics >>> from numpy.lib import scimath >>> scimath.log(-mathematics.exp(1)) == (1+1j*mathematics.pi) Actual Likewise, sqrt(), another basal logarithms, powerfulness() and trig features are appropriately dealt with. Seat their respective docstrings for circumstantial examples. """
It appears that module overlays the basal numpy ufuncs for sqrt, log, log2, logn, log10, powerfulness, arccos, arcsin, and arctanh. That explains the behaviour you are seeing. The underlying plan ground wherefore it is achieved similar that is most likely buried successful a mailing database station location.
