找不到 Python numExpler 模块
原标题:Python numexpr module not found

I installed in the past numexpr successfully on many machine. But now I just cannot manage to get it run on a new Linux system. Essentially I download the tar.gz file and

python setup.py install --home=~/Python/

干得漂亮,我也干过

export PYTHONPATH+=:$HOME/Python/lib/python/

This procedure works nicely for a couple of other modules on the machine, but for numexpr I keep getting

Python 2.6.2 (r262:71600, Jul 22 2011, 11:30:26) 
[GCC 4.4.4 20100726 (Bull 4.4.4-13)] on linux2
Type "help", "copyright", "credits" or "license" for more information.
>>> import numexpr
Traceback (most recent call last):
  File "<stdin>", line 1, in <module>
ImportError: No module named numexpr

我尝试了 numExpl 的1.4.1 和 1.4.2 版本 。 另外, sys. path 被正确设置在 python 环境中( 应该设置) 。

有人知道这里会出什么问题吗?

Thanks, Mark

最佳回答

$HOME/Python/lib/python/ 很可能不是PYTHONPATH的正确值,模块通常安装在安装目录下面的子目录中,通常在 python 等之后有一个版本编号。 我认为只要查看 下的内容就可以解决这个问题。

安装 Anaconda 免费发布 < a href=" "http://continuum.io/ downloads" rel=“ nofollow”>link 。 您使用 python 的编码寿命会更容易得多。 另外, numexpr 已安装并准备使用( 也与其他软件包一起使用 ) 。
