improvements
We are extremely pleased to announce the release of SciPy 1.0, 16 years after version 0.1 saw the light of day. It has been a long, productive journey to get here, and we anticipate many more exciting new features and releases in the future.
Why 1.0 now?¶
A version number should reflect the maturity of a project  and SciPy was a mature and stable library that is heavily used in production settings for a long time already. From that perspective, the 1.0 version number is long overdue.
Some key project goals, both technical (e.g. Windows wheels and continuous integration) and organisational (a governance structure, code of conduct and a roadmap), have been achieved recently.
Many of us are a bit perfectionist, and therefore are reluctant to call something “1.0” because it may imply that it’s “finished” or “we are 100% happy with it”. This is normal for many open source projects, however that doesn’t make it right. We acknowledge to ourselves that it’s not perfect, and there are some dusty corners left (that will probably always be the case). Despite that, SciPy is extremely useful to its users, on average has high quality code and documentation, and gives the stability and backwards compatibility guarantees that a 1.0 label imply.

2017: SciPy 1.0 release
Pauli Virtanen is SciPy’s Benevolent Dictator For Life (BDFL). He says:
Truthfully speaking, we could have released a SciPy 1.0 a long time ago, so I’m happy we do it now at long last. The project has a long history, and during the years it has matured also as a software project. I believe it has well proved its merit to warrant a version number starting with unity.
Since its conception 15+ years ago, SciPy has largely been written by and for scientists, to provide a box of basic tools that they need. Over time, the set of people active in its development has undergone some rotation, and we have evolved towards a somewhat more systematic approach to development. Regardless, this underlying drive has stayed the same, and I think it will also continue propelling the project forward in future. This is all good, since not long after 1.0 comes 1.1.
Travis Oliphant is one of SciPy’s creators. He says:
I’m honored to write a note of congratulations to the SciPy developers and the entire SciPy community for the release of SciPy 1.0. This release represents a dream of many that has been patiently pursued by a stalwart group of pioneers for nearly 2 decades. Efforts have been broad and consistent over that time from many hundreds of people. From initial discussions to efforts coding and packaging to documentation efforts to extensive conference and community building, the SciPy effort has been a global phenomenon that it has been a privilege to participate in.
The idea of SciPy was already in multiple people’s minds in 1997 when I first joined the Python community as a young graduate student who had just fallen in love with the expressibility and extensibility of Python. The internet was just starting to bringing together likeminded mathematicians and scientists in nascent electronicallyconnected communities. In 1998, there was a concerted discussion on the matrixSIG, python mailing list with people like Paul Barrett, Joe Harrington, Perry Greenfield, Paul Dubois, Konrad Hinsen, David Ascher, and others. This discussion encouraged me in 1998 and 1999 to procrastinate my PhD and spend a lot of time writing extension modules to Python that mostly wrapped battletested Fortran and Ccode making it available to the Python user. This work attracted the help of others like Robert Kern, Pearu Peterson and Eric Jones who joined their efforts with mine in 2000 so that by 2001, the first SciPy release was ready. This was long before Github simplified collaboration and input from others and the “patch” command and email was how you helped a project improve.
Since that time, hundreds of people have spent an enormous amount of time improving the SciPy library and the community surrounding this library has dramatically grown. I stopped being able to participate actively in developing the SciPy library around 2010. Fortunately, at that time, Pauli Virtanen and Ralf Gommers picked up the pace of development supported by dozens of other key contributors such as David Cournapeau, Evgeni Burovski, Josef Perktold, and Warren Weckesser. While I have only been able to admire the development of SciPy from a distance for the past 7 years, I have never lost my love of the project and the concept of communitydriven development. I remain driven even now by a desire to help sustain the development of not only the SciPy library but many other affiliated and related opensource projects. I am extremely pleased that SciPy is in the hands of a worldwide community of talented developers who will ensure that SciPy remains an example of how grassroots, communitydriven development can succeed.
Fernando Perez offers a wider community perspective:
The existence of a nascent Scipy library, and the incredible –if tiny by today’s standards– community surrounding it is what drew me into the scientific Python world while still a physics graduate student in 2001. Today, I am awed when I see these tools power everything from high school education to the research that led to the 2017 Nobel Prize in physics.
Don’t be fooled by the 1.0 number: this project is a mature cornerstone of the modern scientific computing ecosystem. I am grateful for the many who have made it possible, and hope to be able to contribute again to it in the future. My sincere congratulations to the whole team!
Highlights of this release¶
Some of the highlights of this release are:
Major build improvements. Windows wheels are available on PyPI for the first time, and continuous integration has been set up on Windows and OS X in addition to Linux.
A set of new ODE solvers and a unified interface to them (
scipy.integrate.solve_ivp
).Two new trust region optimizers and a new linear programming method, with improved performance compared to what
scipy.optimize
offered previously.Many new BLAS and LAPACK functions were wrapped. The BLAS wrappers are now complete.
Upgrading and compatibility¶
There have been a number of deprecations and API changes in this release, which
are documented below. Before upgrading, we recommend that users check that
their own code does not use deprecated SciPy functionality (to do so, run your
code with python Wd
and check for DeprecationWarning
s).
This release requires Python 2.7 or >=3.4 and NumPy 1.8.2 or greater.
This is also the last release to support LAPACK 3.1.x  3.3.x. Moving the lowest supported LAPACK version to >3.2.x was long blocked by Apple Accelerate providing the LAPACK 3.2.1 API. We have decided that it’s time to either drop Accelerate or, if there is enough interest, provide shims for functions added in more recent LAPACK versions so it can still be used.
scipy.cluster
improvements¶
scipy.cluster.hierarchy.optimal_leaf_ordering
, a function to reorder a
linkage matrix to minimize distances between adjacent leaves, was added.
scipy.fftpack
improvements¶
Ndimensional versions of the discrete sine and cosine transforms and their
inverses were added as dctn
, idctn
, dstn
and idstn
.
scipy.integrate
improvements¶
A set of new ODE solvers have been added to scipy.integrate
. The convenience
function scipy.integrate.solve_ivp
allows uniform access to all solvers.
The individual solvers (RK23
, RK45
, Radau
, BDF
and LSODA
)
can also be used directly.
scipy.linalg
improvements¶
The BLAS wrappers in scipy.linalg.blas
have been completed. Added functions
are *gbmv
, *hbmv
, *hpmv
, *hpr
, *hpr2
, *spmv
, *spr
,
*tbmv
, *tbsv
, *tpmv
, *tpsv
, *trsm
, *trsv
, *sbmv
,
*spr2
,
Wrappers for the LAPACK functions *gels
, *stev
, *sytrd
, *hetrd
,
*sytf2
, *hetrf
, *sytrf
, *sycon
, *hecon
, *gglse
,
*stebz
, *stemr
, *sterf
, and *stein
have been added.
The function scipy.linalg.subspace_angles
has been added to compute the
subspace angles between two matrices.
The function scipy.linalg.clarkson_woodruff_transform
has been added.
It finds lowrank matrix approximation via the ClarksonWoodruff Transform.
The functions scipy.linalg.eigh_tridiagonal
and
scipy.linalg.eigvalsh_tridiagonal
, which find the eigenvalues and
eigenvectors of tridiagonal hermitian/symmetric matrices, were added.
scipy.ndimage
improvements¶
Support for homogeneous coordinate transforms has been added to
scipy.ndimage.affine_transform
.
The ndimage
C code underwent a significant refactoring, and is now
a lot easier to understand and maintain.
scipy.optimize
improvements¶
The methods trustregionexact
and trustkrylov
have been added to the
function scipy.optimize.minimize
. These new trustregion methods solve the
subproblem with higher accuracy at the cost of more Hessian factorizations
(compared to dogleg) or more matrix vector products (compared to ncg) but
usually require less nonlinear iterations and are able to deal with indefinite
Hessians. They seem very competitive against the other Newton methods
implemented in scipy.
scipy.optimize.linprog
gained an interior point method. Its performance is
superior (both in accuracy and speed) to the older simplex method.
scipy.signal
improvements¶
An argument fs
(sampling frequency) was added to the following functions:
firwin
, firwin2
, firls
, and remez
. This makes these functions
consistent with many other functions in scipy.signal
in which the sampling
frequency can be specified.
scipy.signal.freqz
has been sped up significantly for FIR filters.
scipy.sparse
improvements¶
Iterating over and slicing of CSC and CSR matrices is now faster by up to ~35%.
The tocsr
method of COO matrices is now several times faster.
The diagonal
method of sparse matrices now takes a parameter, indicating
which diagonal to return.
scipy.sparse.linalg
improvements¶
A new iterative solver for largescale nonsymmetric sparse linear systems,
scipy.sparse.linalg.gcrotmk
, was added. It implements GCROT(m,k)
, a
flexible variant of GCROT
.
scipy.sparse.linalg.lsmr
now accepts an initial guess, yielding potentially
faster convergence.
SuperLU was updated to version 5.2.1.
scipy.spatial
improvements¶
Many distance metrics in scipy.spatial.distance
gained support for weights.
The signatures of scipy.spatial.distance.pdist
and
scipy.spatial.distance.cdist
were changed to *args, **kwargs
in order to
support a wider range of metrics (e.g. stringbased metrics that need extra
keywords). Also, an optional out
parameter was added to pdist
and
cdist
allowing the user to specify where the resulting distance matrix is
to be stored
scipy.stats
improvements¶
The methods cdf
and logcdf
were added to
scipy.stats.multivariate_normal
, providing the cumulative distribution
function of the multivariate normal distribution.
New statistical distance functions were added, namely
scipy.stats.wasserstein_distance
for the first Wasserstein distance and
scipy.stats.energy_distance
for the energy distance.
Deprecated features¶
The following functions in scipy.misc
are deprecated: bytescale
,
fromimage
, imfilter
, imread
, imresize
, imrotate
,
imsave
, imshow
and toimage
. Most of those functions have unexpected
behavior (like rescaling and type casting image data without the user asking
for that). Other functions simply have better alternatives.
scipy.interpolate.interpolate_wrapper
and all functions in that submodule
are deprecated. This was a never finished set of wrapper functions which is
not relevant anymore.
The fillvalue
of scipy.signal.convolve2d
will be cast directly to the
dtypes of the input arrays in the future and checked that it is a scalar or
an array with a single element.
scipy.spatial.distance.matching
is deprecated. It is an alias of
scipy.spatial.distance.hamming
, which should be used instead.
Implementation of scipy.spatial.distance.wminkowski
was based on a wrong
interpretation of the metric definition. In scipy 1.0 it has been just
deprecated in the documentation to keep retrocompatibility but is recommended
to use the new version of scipy.spatial.distance.minkowski
that implements
the correct behaviour.
Positional arguments of scipy.spatial.distance.pdist
and
scipy.spatial.distance.cdist
should be replaced with their keyword version.
Backwards incompatible changes¶
The following deprecated functions have been removed from scipy.stats
:
betai
, chisqprob
, f_value
, histogram
, histogram2
,
pdf_fromgamma
, signaltonoise
, square_of_sums
, ss
and
threshold
.
The following deprecated functions have been removed from scipy.stats.mstats
:
betai
, f_value_wilks_lambda
, signaltonoise
and threshold
.
The deprecated a
and reta
keywords have been removed from
scipy.stats.shapiro
.
The deprecated functions sparse.csgraph.cs_graph_components
and
sparse.linalg.symeig
have been removed from scipy.sparse
.
The following deprecated keywords have been removed in scipy.sparse.linalg
:
drop_tol
from splu
, and xtype
from bicg
, bicgstab
, cg
,
cgs
, gmres
, qmr
and minres
.
The deprecated functions expm2
and expm3
have been removed from
scipy.linalg
. The deprecated keyword q
was removed from
scipy.linalg.expm
. And the deprecated submodule linalg.calc_lwork
was
removed.
The deprecated functions C2K
, K2C
, F2C
, C2F
, F2K
and
K2F
have been removed from scipy.constants
.
The deprecated ppform
class was removed from scipy.interpolate
.
The deprecated keyword iprint
was removed from scipy.optimize.fmin_cobyla
.
The default value for the zero_phase
keyword of scipy.signal.decimate
has been changed to True.
The kmeans
and kmeans2
functions in scipy.cluster.vq
changed the
method used for random initialization, so using a fixed random seed will
not necessarily produce the same results as in previous versions.
scipy.special.gammaln
does not accept complex arguments anymore.
The deprecated functions sph_jn
, sph_yn
, sph_jnyn
, sph_in
,
sph_kn
, and sph_inkn
have been removed. Users should instead use
the functions spherical_jn
, spherical_yn
, spherical_in
, and
spherical_kn
. Be aware that the new functions have different
signatures.
The crossclass properties of scipy.signal.lti
systems have been removed.
The following properties/setters have been removed:
Name  (accessing/setting has been removed)  (setting has been removed)
StateSpace  (
num
,den
,gain
)  (zeros
,poles
)TransferFunction (
A
,B
,C
,D
,gain
)  (zeros
,poles
)ZerosPolesGain (
A
,B
,C
,D
,num
,den
)  ()
signal.freqz(b, a)
with b
or a
>1D raises a ValueError
. This
was a corner case for which it was unclear that the behavior was welldefined.
The method var
of scipy.stats.dirichlet
now returns a scalar rather than
an ndarray when the length of alpha is 1.
Other changes¶
SciPy now has a formal governance structure. It consists of a BDFL (Pauli Virtanen) and a Steering Committee. See the governance document for details.
It is now possible to build SciPy on Windows with MSVC + gfortran! Continuous integration has been set up for this build configuration on Appveyor, building against OpenBLAS.
Continuous integration for OS X has been set up on TravisCI.
The SciPy test suite has been migrated from nose
to pytest
.
scipy/_distributor_init.py
was added to allow redistributors of SciPy to
add custom code that needs to run when importing SciPy (e.g. checks for
hardware, DLL search paths, etc.).
Support for PEP 518 (specifying build system requirements) was added  see
pyproject.toml
in the root of the SciPy repository.
In order to have consistent function names, the function
scipy.linalg.solve_lyapunov
is renamed to
scipy.linalg.solve_continuous_lyapunov
. The old name is kept for
backwardscompatibility.
