isympy startup error

[Mani Chandra]

Hello,

I'm trying to use the binary from the git source tree since I wanted the latest version of simplify(), but I get the following error when I try to use bin/isympy.

Traceback (most recent call last):

  File "isympy", line 162, in <module>

    main()

  File "isympy", line 159, in main

    init_session(ipython, **args)

TypeError: init_session() got an unexpected keyword argument 'pretty_print'

What can I do to fix this?

Thanks,

Mani Chandra

Hi.

Can you give more information about your system? What version of
Python do you have installed? What kind of terminal are you using (in
particular, does it support unicode)? Are you passing any options to
the isympy command?

Also make sure that you run exactly bin/isympy from the directory you cloned SymPy's repository to, because otherwise a system-wide installed SymPy (if exists) will be used by Python in preference to the git version.

Hi,

1) Python version: Python 2.7.1 (Enthought Python Distribution 7.0)

2) Terminal: Gnome terminal

3) I run it using ./isympy in the bin folder.

This is your problem. You need to run it from the sympy folder, i.e.,
you should be running ./bin/isympy. Otherwise, as Mateusz pointed
out, it will try to use an installed version of sympy rather than the
git version (and it looks like the installed version is incompatible
with our current git version).
