Question

运行：

from numpy import *

显示：

Traceback (most recent call last):
  File "<stdin>", line 1, in <module>
  File "C:\Python27\lib\site-packages\numpy\__init__.py", line 170, in <module>
    from . import add_newdocs
  File "C:\Python27\lib\site-packages\numpy\add_newdocs.py", line 13, in <module>
    from numpy.lib import add_newdoc
  File "C:\Python27\lib\site-packages\numpy\lib\__init__.py", line 17, in <module>
    from . import scimath as emath
ImportError: cannot import name scimath

求帮助。

Answer 1

错误出在这里, from . 是相对路径, 显然你的 python 没设置好.

from . import scimath as emath

最简单的就是用安装一个anaconda发行版的 python, 别再自己折腾了, 数值计算那几个package 安装麻烦的很, 小毛病一堆, 而且windows估计更麻烦.
