【问题描述】：

我在 Python 2.7 中使用 Skimage 包已经有一段时间了。

最近我将我的 Ubuntu 升级到 14.10，现在我无法从 Skimage 包中导入过滤器（以前是过滤器）。

Python 2.7.9 (default, Apr  2 2015, 15:33:21) 
[GCC 4.9.2] on linux2
Type "copyright", "credits" or "license()" for more information.
>>> from skimage import filters

标签： python filter scipy importerror scikit-image

【解决方案1】：

试试

pip install -U scikit-image

【讨论】：

【解决方案2】：

试试

from skimage import filter

而不是

from skimage import filters

我遇到了同样的错误，它已经解决了

【解决方案3】：

问题在于 scikit-image 的版本。在 skimage '0.10.1' 中没有名为 'filters' 的模块，因为它有 'filter'。所以使用命令'sudo pip install --upgrade scikit-image'升级它，它将升级到包含模块'filters'而不是'filter'的版本'0.13.1'。
