错误重装SciPy

Question

在下面运行my_script.py将返回重新加载过程中的一个错误，最后一个错误是：

ImportError: No module named moves

这似乎是由这句话引发的

from scipy.lib.six.moves import xrange

在文件scipy/stats/stats.pyc中。这会是个窃听器吗？操作系统我的安装有问题吗？

my_script.py:

import my_package.my_module as my_module
reload(my_module)

my_module.py:

from scipy.stats import gaussian_kde

Answer 1

您的SciPy版本(0.13.3)对xrange和scipy.lib.six.moves (https://github.com/scipy/scipy/blob/maintenance/0.13.x/scipy/lib/six.py#L188)具有一定的“魔力”。实际上，scipy.lib.six.moves不是存储在scipy/lib/six/源目录中，而是添加到Python解释器内存中的已知模块中，因此可能会发生奇怪的交互。

如果没有在代码中重新加载my_module呢？这也许能解释你的问题。

我有SciPy 0.14，我没有注意到您的代码有任何问题，所以升级也可以解决这个问题。

Answer 2

乌本图？试试这个：

sudo apt-获取安装python-6

如果这不起作用，您可以尝试从源代码中编译Scipy ( github上的最新源代码没有解决我的问题，也许您可以尝试0.13.3，从http://mail.scipy.org/pipermail/scipy-user/2014-February/035419.html下载)

我如何解决这个问题：

• 从构建最新的源代码中安装
• 更新python-6
