problem installing mpmath v .17 in Python 3.2.1

[Richard D. Moores]

Win 64-bit Vista
Python 3.1.3 and 3.2.1

I need 3.2.1 in order to use gmpy2 (see http://code.google.com/p/gmpy/)

I downloaded http://mpmath.googlecode.com/files/mpmath-0.17.zip and
installed in Python 3.1.3 last February. I now have Python 3.2.1 and
tried the same installation, but get

>>> import mpmath
Traceback (most recent call last):

line 302, in <module>
sqrtrem = gmpy.sqrtrem
builtins.AttributeError: 'module' object has no attribute 'sqrtrem'

What to do?

Thanks,

I commited several fixes for compatibility with gmpy2 since the 0.17
release.

For your particular issue, modify libintmath.py as follows:

Change the lines:

if BACKEND == 'gmpy':
isqrt_small = isqrt_fast = isqrt = gmpy.sqrt
sqrtrem = gmpy.sqrtrem

to:

if BACKEND == 'gmpy':
if gmpy.version() >= '2':
isqrt_small = isqrt_fast = isqrt = gmpy.isqrt
sqrtrem = gmpy.isqrt_rem
else:
isqrt_small = isqrt_fast = isqrt = gmpy.sqrt
sqrtrem = gmpy.sqrtrem

Yes! That did it. Thanks very much.
