Error: import Point3D of Geometry Module of sympy0.7.5 in Blender2.71 I want to use  Geometry Module of sympy0.7.5 in Blender 2.71 (64 Bit). 
  But I got some error when I try to do "from sympy import Point3D":
        ImportError: cannot import name 'Point3D'.

Here is what I have done:


Clone the latest sympy0.7.5:  

git clone https://github.com/sympy/sympy

Install it in python3.4.0 [MSC v.1600 64 bit (AMD64)] (same python version in blender 2.71 except MSC v.1800 64 bit (AMD64)). The sympy's location is in c:\Python34\Lib\site-packages\.
Test from sympy import Point3D"- in python3.4, everything is fine.
Copy sympy folder in
c:\Python34\Lib\site-packages\ to
c:\Program Files\Blender Foundation\Blender\2.71\python\lib\
In python console of the blender, it works for

   from sympy import *
   from sympy import Point
   ...
  but failed for
   from sympy import Point3D
I found the solution: 


get a fresh copy of sympy by git;
simply copy the subdirectory "sympy" into the corresponding site-packages directory of my blender:
  c:\Program Files\Blender Foundation\Blender\2.71\python\lib\site-packages\

Every is fine now.
