我想ufuncify Sympy的FallingFactorial函数,以便它类似于数组输入上的numpy,而不仅仅是一对整数。
我尝试了以下代码:
from sympy.functions.combinatorial.factorials import FallingFactorial
from sympy.utilities.autowrap import ufuncify
from sympy.abc import A,B
FF = ufuncify((A,B), FallingFactorial(A,B))
但是我收到以下错误:
Traceback (most recent call last):
File "<stdin>", line 1, in <module>
File "/usr/lib/python2.7/dist-packages/sympy/utilities/autowrap.py", line 486, in ufuncify
return autowrap(C.Equality(y[i], f(*args)), **kwargs)
File "/usr/lib/python2.7/dist-packages/sympy/utilities/autowrap.py", line 404, in autowrap
return code_wrapper.wrap_code(routine, helpers=helps)
File "/usr/lib/python2.7/dist-packages/sympy/utilities/autowrap.py", line 141, in wrap_code
mod = __import__(self.module_name)
ImportError: ./wrapper_module_0.so: undefined symbol: fallingfactorial_
上面的代码是否适用于其他人或我有什么问题? 我正在使用Python 2.7和Sympy 0.7.4.1
