python - import skimage 有效，但 skimage.measure 无效

Question

我得到了

from skimage.measure import find_contours
---------------------------------------------------------------------------
ImportError                               Traceback (most recent call last)
<ipython-input-2-2cf88a5f2300> in <module>()
----> 1 from skimage.measure import find_contours

ImportError: No module named 'skimage.measure' 

同样，如果我简单地导入 skimage 并尝试调用 skimage.measure.find_contours，我会得到

AttributeError: module 'skimage' has no attribute 'measure' 

import skimage 不会抛出错误，只是似乎没有附加任何东西:

import skimage

skimage.__version__
---------------------------------------------------------------------------
AttributeError                            Traceback (most recent call last)
<ipython-input-4-846cd4ef3ef8> in <module>()
----> 1 skimage.__version__

AttributeError: module 'skimage' has no attribute '__version__' 

skimage 已安装:

我在这里找到了类似问题的人https://gitmemory.com/issue/scikit-image/scikit-image/3731/505817873但没有解决方案。

我也试过

from skimage import measure

ImportError: cannot import name 'measure' 

Answer 1

在 0.18.x 版本中，它又发生了变化。执行以下操作:

from skimage import metrics

metrics.structural_similarity(grayA, grayB, full=True)
