我有一个脚本，我在Red Hat 4.4.7上运行成功：
>>> import numpy
>>> numpy.version.version
'1.9.1'
>>> numpy.linspace(3,4,5,dtype=int)
array([3, 3, 3, 3, 4])
在我的Windows安装上，即使更新numpy（pip install -U numpy）后，我也收到错误：
In[3]: import numpy
In[4]: numpy.version.version
Out[4]: '1.9.1'
In[5]: numpy.linspace(3,4,5,dtype=int)
Traceback (most recent call last):
File "C:\Users\lb\AppData\Local\Enthought\Canopy\User\lib\site-packages\IPython\core\interactiveshell.py", line 2883, in run_code
exec(code_obj, self.user_global_ns, self.user_ns)
File "<ipython-input-5-cce2ab26cfad>", line 1, in <module>
numpy.linspace(3,4,5,dtype=int)
TypeError: linspace() got an unexpected keyword argument 'dtype'
为什么这种行为不同？除了numpy版本，我还应该检查什么？
编辑：
print(repr(numpy.core.function_base))
<module 'numpy.core.function_base' from 'C:\Users\lb\AppData\Local\Enthought\Canopy\User\lib\site-packages\numpy\core\function_base.pyc'>
print(repr(numpy.__path__))
['C:\\Users\\lb\\AppData\\Local\\Enthought\\Canopy\\User\\lib\\site-packages\\numpy']
print(numpy.linspace.__module__)
numpy.core.function_base
在C：\ Users \ lb \ AppData \ Local \ Enthought \ Canopy \ User \ Lib \ site-packages \ numpy \ core \ function_base.py的第8行，我有：
def linspace(start, stop, num=50, endpoint=True, retstep=False):
所以，我想我搞砸了pip更新......
