Question

我正在尝试使用skimage.viewer.canvastools.PaintTool绘制覆盖蒙版，并且无法解决类型错误。

我成功生成了一个ImageViewer窗口，该窗口带有一个半透明的覆盖蒙版和一个用于绘画的彩色像素光标，但是当我尝试绘画时没有任何响应。当我关闭ImageViewer时，我收到“ TypeError：切片索引必须为整数或无，或者具有 index 方法”

from skimage.viewer.canvastools import PaintTool
from skimage.viewer import  ImageViewer

viewer = ImageViewer(img) # grayscale image
color = np.shape(img) # 2D tuple
p = PaintTool(viewer,color,5,0.5)
viewer.show()

我希望ImageViewer窗口弹出并允许在我的图像上绘制，但是会引发TypeError。

Traceback (most recent call last):

如何修复skimage.viewer.canvastools.PaintTool中的类型错误
