[gentoo-science] [sage-on-gentoo]mpmath testing

[François Bissey]

After sympy I would like testing report on mpmath.

mpmath has an interesting relationship with sage.
sage includes mpmath and if mpmath finds sage it uses bits of it.

So I'd like to know what sage-on-gentoo users get when
they do "import mpmath" from a python2.6 shell.
I'd like reports of success as well as error along with
the version of sage installed (4.5.3, 4.6alpha3 or other).

Thanks,
Francois

Here with Sage 4.5.3 from a python shell; import sage.all, import sympy  
or import mpmath all produce the expected result - one is returned to  
the python prompt after the import. With Sage 4.6alpha3 if each import  
is performed from a separate python shell then each import returns

Traceback (most recent call last):
   File "/usr/bin/sage-cleaner", line 25, in <module>
     DOT_SAGE = os.environ['DOT_SAGE']
   File "/usr/lib/python2.6/UserDict.py", line 22, in __getitem__
     raise KeyError(key)
KeyError: 'DOT_SAGE'

If from the same python shell the three imports are performed then only  
the first import returns the Traceback.

Thank you Steve,

Could you send me the result of 
printenv | grep SAGE
from the machine running sage-4.5.3. For mpmath with sage-4.6alpha3 
I was expecting this error:

I posted about it on the sage-release, where we talk about the sage-4.6 pre 
releases, and no one else has the problem so far. If you don't have it either
that may be a problem on my machine.

printenv | grep SAGE gives (on _all_ installations)

I don't get the above with an import of mpmath. Just a thought, could  
it be mpfr-related. I'm using
mpfr-2.4.2_p3 here.

I am a bit surprised you always get the error building sympy (prior to my last 
commit) and no error when importing from the python shell with 4.5.3.
That's a bit of a puzzler.

I think it could be my using mpfr-3.0.0_p3 yes. I am checking that right now.
