python - 在Python中使用scipy错误中的stats包？

Question

我尝试在 Python 中使用 scipy stats 包，但收到以下错误(在 Mac OS X 上):

$ python
Python 2.6.5 (r265:79359, Mar 24 2010, 01:32:55) 
[GCC 4.0.1 (Apple Inc. build 5493)] on darwin
Type "help", "copyright", "credits" or "license" for more information.
>>> import scipy
>>> from scipy import stats

然后我收到错误:

Traceback (most recent call last):
  File "<stdin>", line 1, in <module>
  File "/Library/Frameworks/Python.framework/Versions/2.6/lib/python2.6/site-packages/scipy-0.9.0.dev-py2.6-macosx-10.6-universal.egg/scipy/stats/__init__.py", line 7, in <module>

知道这里会发生什么吗？

谢谢。

该消息表示 0.9.0-dev scipyspecial/_cephes.so 运行时库中缺少 aswfa(角球面波函数？)。(它存在于 0.7.2 中，nm -gpvspecial/_cephes.so | egrep aswfa。我没试过0.8.0rc1 .)

最好等待专家修复它。并且一定要按照 John Salvatier 的建议询问 scipy-user 或 scipy-dev。
