Release Notes for 1.7 - sympy/sympy GitHub Wiki

These are the release notes for SymPy 1.7. You can also find release notes for previous versions.

SymPy 1.7 was released on 29th November 2020.

This version of SymPy has been tested on Python 3.6, 3.7, 3.8, 3.9 and PyPy. See our Python version support policy for more information on when we plan to drop support for older Python versions.

Note in particular that SymPy 1.5.1 was the last release to support Python 2.7. SymPy 1.7 will not work on Python 2.7. Python 2.7 users should install SymPy 1.5.1 and will not be able to install any further SymPy updates without updating to Python 3.

Install SymPy with

pip install -U sympy

or if you use Anaconda

conda install sympy

Highlights

There are many changes in 1.7 (see below).

Backwards compatibility breaks and deprecations

  • core

    • Modules and names that were accidentally importable from sympy are no longer importable. In sympy 1.6 importing and using these names would give a deprecation warning. In sympy 1.7 these names are removed. As an example from sympy import add would need to be from sympy.core import add or import sympy.core.add as add. (#19554 by @oscarbenjamin)

    • DEPRECATION: Using non-Expr args in Add, Mul or Pow is now deprecated (#19445 by @oscarbenjamin)

  • diffgeom

    • Manifold.patches attribute is deprecated. (#19368 by @JSS95 and @mcpl-sympy)

    • Patch.coord_systems attribute is deprecated. (#19368 by @JSS95 and @mcpl-sympy)

    • Class signature names of CoordSystem is deprecated. CoordinateSymbol class and CoordSystem.symbols attribute are introduced instead. (#19368 by @JSS95 and @mcpl-sympy)

    • CoordSystem.transforms, CoordSystem.connect_to, and CoordSystem.coord_tuple_transform_to are deprecated. Class signature relations, CoordSystem.transformation and CoordSystem.transform are introduced instead. (#19368 by @JSS95 and @mcpl-sympy)

  • printing

    • sympy.printing.pretty.pretty_symbology.xstr has been deprecated (#20081 by @eric-wieser)

    • The unicode argument to sympy.printing.stringpict.prettyForm has been deprecated (#20081 by @eric-wieser)

    • The deprecation of calling preview with viewer="StringIO" is now expired instead of forgotten (a regression in 1.6.0) (#19905 by @eric-wieser)

    • The modules sympy.printing.ccode, sympy.printing.fcode, and sympy.printing.cxxcode have been renamed to sympy.printing.c, sympy.printing.fortran, and sympy.printing.cxx, respectively. This was done to avoid conflicts that occur when a module name is the same as a function name. The modules are still importable under their old names but doing so is deprecated and a warning will be given (#19908 by @asmeurer)

    • from sympy.printing.codeprinter import Assignment no longer works. You should use from sympy.codegen import Assignment, which is where Assignment has lived since SymPy 1.1. (#19908 by @asmeurer)

    • Calling preview with viewer="file" no longer looks for a file executable (a regression in 1.6.0) (#19905 by @eric-wieser)

  • solvers

    • solve_linear_system is now a thin wrapper for linsolve. It is recommended to use linsolve in new code. solve_linear_system maybe deprecated or removed in future. (#18814 by @oscarbenjamin)
  • utilities

    • find_executable is deprecated in favor of the builtin shutil.which. (#19634 by @eric-wieser)

Changes

  • algebras

  • codegen

    • Added support for generating calls to scipy.special.cosm1. (#20011 by @bjodah)
    • sympy.codegen and sympy.combinatorics are no longer imported as part of from sympy import *. The codegen and combinatorics modules do not have any names that are included in the top-level namespace, so their being imported with the top-level SymPy was a mistake. This improves the import time of from sympy import *. (#19908 by @asmeurer)
    • Added support for generating calls to numpy.logaddexp & numpy.logaddexp2. (#19880 by @bjodah)

    • Fix bugs to the parser of matrix expressions in order to build CodegenArray objects correctly. (#19197 by @Upabjojr)

  • combinatorics

    • Fixed a bug in PermutationGroup.minimal_blocks caused by modifying a list while iterating over its indices. (#19954 by @ilya-pchelintsev)
  • concrete

  • core

    • Fixed a few broken cases of expr.is_integer (#20450 by @coproc and @tbennun)

    • Modules and names that were accidentally importable from sympy are no longer importable. In sympy 1.6 importing and using these names would give a deprecation warning. In sympy 1.7 these names are removed. As an example from sympy import add would need to be from sympy.core import add or import sympy.core.add as add. (#19554 by @oscarbenjamin)

    • Zero raised to power Negative Infinity gives ComplexInfinity(zoo) instead of zero (#20212 by @sidhu1012)

    • Extensible add, mul and power functions are introduced to allow sympy objects to define what classes should be used for them in place of Add, Mul and Pow (e.g. matrices use MatAdd). This is an experimental approach aimed at enabling the behaviour of core routines (expand, collect, etc) to be customised by user-defined types (e.g. MatAdd rather than Add). This mechanism is still experimental, is not fully implemented across the core and might be changed or removed in a future release of sympy. (#19463 by @JSS95 and @mcpl-sympy)

    • divmod on sympy.Float with 0 numerator now results in (0, 0). (#20109 by @eriknw)

    • Remove optional dependency on fastcache (#19492 by @pbrady)

    • DEPRECATION: Using non-Expr args in Add, Mul or Pow is now deprecated (#19445 by @oscarbenjamin)

    • When creating an Add or Mul with evaluate=False identities (0 or 1) are no longer removed. (#19450 by @oscarbenjamin)

    • Fixes _eval_nseries() function of mul.py (#19369 by @sachin-4099)

    • Sum is now included in count_ops results (#19261 by @smichr)

    • match has been optimized to improve term-matching in Add (#19261 by @smichr)

    • match will automatically ignore bound symbols when matching (#19261 by @smichr)

    • match results will no longer contain extraneous symbols (only those requested) (#19261 by @smichr)

    • as_dummy should give a canonical result for expressions having bound symbols (#19261 by @smichr)

    • Lambdas written in terms of different symbols will no longer compare equal; this was an abuse of the Python == operator (#19261 by @smichr)

    • expr: A new method is_meromorphic is added. (#19306 by @jksuom)

  • diffgeom

    • Manifold.patches attribute is deprecated. (#19368 by @JSS95 and @mcpl-sympy)

    • Patch.coord_systems attribute is deprecated. (#19368 by @JSS95 and @mcpl-sympy)

    • Class signature names of CoordSystem is deprecated. CoordinateSymbol class and CoordSystem.symbols attribute are introduced instead. (#19368 by @JSS95 and @mcpl-sympy)

    • CoordSystem.transforms, CoordSystem.connect_to, and CoordSystem.coord_tuple_transform_to are deprecated. Class signature relations, CoordSystem.transformation and CoordSystem.transform are introduced instead. (#19368 by @JSS95 and @mcpl-sympy)

  • integrals

  • interactive

    • The _repr_latex_, _repr_svg_, and _repr_png_ methods of subclasses of sympy objects are no longer discarded when init_printing() is called. (#19944 by @eric-wieser)
  • logic

    • Binary boolean operators on Boolean objects no longer coerce strings (#20093 by @eric-wieser)
  • matrices

    • Adding an array and a matrix now consistently gives TypeError. (#20159 by @sidhu1012)

    • changed subs function to check if input is zip (#19159 by @czgdp1807 and @gfolbe318)

    • added tests in test_commonmatrix.py (#19159 by @czgdp1807 and @gfolbe318)

    • Fixed a bug in the implementation of Sylvester's criterion for determining if a matrix is positive semidefinite. (#19556 by @galbwe)

    • Explicit non-matrix are treated as scalar (#19533 by @mloubout)

    • QRdecomposition will return matrices with zero rows and columns for zero rank matrices. e.g. Matrix([0, 0, 0], [0, 0, 0], [0, 0, 0](/sympy/sympy/wiki/0,-0,-0],-[0,-0,-0],-[0,-0,-0)) will be decomposed with Matrix(3, 0, []) and Matrix(0, 3, []) (#19319 by @sylee957)

Also, modified the data type for int and float to intc and float32 respectively, replacing integer and real (#19230 by @smitgajjar)

    • Added support for shorthand operators in C parser: +=, -=, *=, /= and %= (#19230 by @smitgajjar)

    • Removed the assumption of value of a variable, if it is not initialized while variable declaration(e.g.; in case of int a;, the value of a was assumed to be Integer(0), in case of float b;, the value of b was assumed to be Float(0.0) and in case of bool c;, the value of c was assumed to be S.false). Also, removed the assumption of default value of formal parameters while parameter declaration in function definition or function prototype (e.g.; in case of function definition void func(int a, float b) { //some code }, default value of formal parametersa and b were assumed to be Integer(0) and Float(0.0) respectively) (#19230 by @smitgajjar)

  • physics.control

    • VectorLatexPrinter now respects the symbol_names setting when printing dynamicsymbols (#19684 by @eric-wieser)

    • VectorLatexPrinter now know about the same trig functions as the regular printer (#19684 by @eric-wieser)

  • plotting

    • capability to subclass Basebackend and specify it to the plotting functions, thus creating plots with other plotting libraries (#20463 by @oscarbenjamin)
    • Fixed plot3d_parametric_line plotting curves out of the box. (#19252 by @sylee957)

    • Fixed Poly initialized with FracElement raising SympifyError. (e.g. dom = ZZ.frac_field(x); Poly(dom(x+2), y, domain=dom)) (#19659 by @sylee957)

    • Add division to finite extensions. (#19593 by @gschintgen and @jksuom)

    • Fixed GCD to always return a non-negative constant. (#19569 by @KaustubhDamania)

    • added new domains for Gaussian integers and rationals (#15396 by @jksuom and @smichr)

    • Add the Gaussian domains ZZ_I and QQ_I to Poly. Make Poly use the Gaussian domains automatically when I is present in the input. Add factorisation over the Gaussian integers (ZZ_I). The polys keyword argument gaussian=True now results in the domain QQ_I rather than the extension field QQ<I>. (#15396 by @oscarbenjamin)

    • improvement of dup_zz_mignotte_bound(f, K) by Knuth-Cohen bound (#19254 by @lagamura)

  • printing

    • sympy.printing.pretty.pretty_symbology.xstr has been deprecated (#20081 by @eric-wieser)

    • The unicode argument to sympy.printing.stringpict.prettyForm has been deprecated (#20081 by @eric-wieser)

    • The unicode attribute of sympy.printing.stringpict.prettyForm has been deprecated (#20081 by @eric-wieser)

    • The modules sympy.printing.ccode, sympy.printing.fcode, and sympy.printing.cxxcode have been renamed to sympy.printing.c, sympy.printing.fortran, and sympy.printing.cxx, respectively. This was done to avoid conflicts that occur when a module name is the same as a function name. The modules are still importable under their old names but doing so is deprecated and a warning will be given (#19908 by @asmeurer)

    • from sympy.printing.codeprinter import Assignment no longer works. You should use from sympy.codegen import Assignment, which is where Assignment has lived since SymPy 1.1. (#19908 by @asmeurer)

    • Calling preview with viewer="file" no longer looks for a file executable (a regression in 1.6.0) (#19905 by @eric-wieser)

    • When printing, NDimArray now respects keyword-arguments to sstr (#19903 by @eric-wieser)

    • preview no longer fails with ValueError if the preamble contains a % character. (#19858 by @eric-wieser)

    • Types which are not recognized by the LaTeX printer no longer have their __str__ interpreted as LaTeX, and have their str(...) printed as pre-formatted text as if they were printed normally. This includes the builtin str type: latex("hello") now results in the latex \mathtt{\text{hello}}.

      If a custom type intends to be interpreted as latex, it should define the _latex hook as described in the docs:

      def _latex(self, printer):
          return str(self)  # indicate that the result of __str__ is LaTeX-compatible
      

      To print a string containing LaTeX math using MathJax, use

      import IPython
      IPython.display.Math(string)

    • LatexPrinter._print is no longer called on strings which have already been converted to Latex. (#19614 by @eric-wieser)

    • A new sympy.printing.defaults.Printable base class was added, which is a mixin providing _repr_latex_ in terms of LatexPrinter().doprint(). Any user type which subclasses this will opt into init_printing. (#19425 by @eric-wieser)

    • Printing unevaluated Muls with multiple Number factors will show all factors strictly in order. Identities will also be shown explicitly. (#19450 by @oscarbenjamin)

    • Earlier expr and sets were treated equal which gave incorrect output for some set functions(mainly : - in, is_subset), made sets and expr not to be equal (#20208 by @sidhu1012)
    • nested multi-symbol first arg for ConditionSet now handled with subs/as_dummy (#19512 by @smichr)

    • the bound symbols cannot be replaced with subs (#19512 by @smichr)

    • the error checking for mismatched signatures for sym and the base set has been improved (#19512 by @smichr)

    • In dsolve there is no a general solver that can solve systems of constant coefficient non-homogeneous first order ODEs of any size in terms of integrals. (#19341 by @mijo2)
