How to find version number of CAS used by sage

asked 2018-06-17 02:14:20 -0500

Nasser gravatar image

Hello. sagemath newbie here.

When I type

r=integrate(sqrt(x),x,algorithm="sympy")

or

 r=integrate(sqrt(x),x,algorithm="fricas")

or

 r=integrate(sqrt(x),x,algorithm="maxima")

etc..

what command to use to find what version numbers of those CAS it is using? For Fricas, I just installed it, so I know it is 1.3.3-1, But in general, how does one ask sage to provide this information? Is there a command to use?

Will these be the same obtained on the bash command line when doing

 $which maxima
 $which fricas

If that is the case, then I can find the version numbers easily. But what about sympy? How do I know which sympy sage is using to make sure.

Thank you,

--Nasser

You can use the installed_packages function that returns a dictionary package name -> version, e.g.

sage: ver = installed_packages()
sage: ver['maxima']
'5.41.0'
sage: ver['fricas']
'1.3.2'

thanks. For some reason, the above command gives me an error on 8.3.beta5 (which is the version that got installed automatically for me when I selected sage from Manjaro Linux package manager). This is the error

         sage: ver = installed_packages()

         /usr/lib/python2.7/site-packages/sage/misc/package.py in installed_packages(exclude_pip)
          285         installed.update(pip_installed_packages())
          286     # Sage packages should override pip packages (Trac #23997)
           --> 287     installed.update(pkgname_split(pkgname) for pkgname in os.listdir(SAGE_SPKG_INST))
             288     return installed
            289 

           OSError: [Errno 2] No such file or directory: '/usr/var/lib/sage/installed'

@Nasser -- Some Linux distributions package Sage to work with the system's Python, rather than ship its own Python. This might be the case for ArchLinux, on which Manjaro Linux is based.

The notion of installed packages might work differently there.

Starting Sage by launching sage in the terminal gives you a banner which includes the version of Sage.

$ sage
┌────────────────────────────────────────────────────────────────────┐
│ SageMath version 8.3.beta2, Release Date: 2018-05-18               │
│ Type "notebook()" for the browser-based notebook interface.        │
│ Type "help()" for help.                                            │
└────────────────────────────────────────────────────────────────────┘
┏━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━┓
┃ Warning: this is a prerelease version, and it may be unstable.     ┃
┗━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━┛
sage:

You can also get just the version of Sage without starting Sage, by running sage -v or sage --version in the terminal.

$ sage -v
SageMath version 8.3.beta2, Release Date: 2018-05-18

$ sage --version
SageMath version 8.3.beta2, Release Date: 2018-05-18

You can start Sage without getting the banner by running sage -q (q is for quiet) in the terminal.

$ sage -q
sage:

Combining those, you can get the version without the full banner, by running sage -v; sage -q in the terminal:

$ sage -v: sage -q
SageMath version 8.3.beta2, Release Date: 2018-05-18

Once Sage is started (illustrated below in the Sage REPL but would work in the SageNB or Jupyter interface too), you can get its version number by typing:

sage: version()
'SageMath version 8.3.beta2, Release Date: 2018-05-18'

For the installed Python packages (such as NumPy, SciPy, SymPy...), you can usually get the version number as follows:

sage: import numpy
sage: print(numpy.__version__)
1.13.3

sage: import sympy
sage: print(sympy.__version__)
1.1.1

sage: import scipy
sage: print(scipy.__version__)
0.19.1

etc., but sometimes it is version, or version_info rather than __version__.

sage: import tornado
sage: print(tornado.version)
4.5.2
sage: print(tornado.version_info)
(4, 5, 2, 0)

You could try typing the name of the module followed by .__ver and hit the TAB key, if that autocompletes to .__version__ then use that, otherwise try typing the name of the module followed by .ver and hit the TAB key.

For other software shipped with Sage, which are not Python packages, sometimes you get the version number as follows (again you could type the software's name followed by .ver and hit the TAB key to see the autocompletion to .version):

sage: print(maxima.version())
5.41.0

sage: print(r.version())
((3, 4, 4), 'R version 3.4.4 (2018-03-15)')

sage: print(gap.version())
4.8.6

sage: print(pari.version())
[2, 10, 0]

sage: print(gp.version())
((2, 10, 0), 'GP/PARI CALCULATOR Version 2.10.0 (development git-88fb5b3)')

The output for Singular is quite a bit longer...

sage: print(singular.version())

Another way to get to the version number information, especially if you built Sage from source, is to use the terminal, and change directory to the upstream subdirectory of the Sage installation directory.

For instance, if the Sage installation directory is /home/user/SageMath, then do this in a terminal:

$ cd /home/user/SageMath/upstream
$ ls

and you will see the tarballs for many of the included software and Python packages, which include the version numbers. In my case:

$ cd /home/user/SageMath/upstream

thanks for the useful information.

       print(maxima.version())

works, but

       print(sympy.version())

gave NameError name 'sympy' is not defined. But I can find sympy version from python itself, which I assume is the same one used by sage. That is why I asked. I wanted to make sure I am looking at the correct sympy used by sage.

As I wrote, for Python packages, such as SymPy, you write:

import sympy
print(sympy.__version__)

and you get the answer, currently

1.1.1

If you do this in your system's Python, you get the version of SymPy in your system's Python. If you do this in your Anaconda's Python, you get the version of SymPy in your Anaconda's Python. If you do this in your Sage's Python or in Sage, you get the version of SymPy in your Sage's Python.
