TypeError: load() 缺少 1 个必需的位置参数：从 skimage.segmentation 导入 felzenszwalb、slic、quickshift、watershed 时的“Loader”

Question

I was trying to run the simple test script of skimage for superpixels segmentation . However, when I executed the code ( python -m src ), I got this error:

Traceback (most recent call last):

My conda environnement was installed from this requirements.txt file:

opencv-python==4.5.4.60
nptyping==1.4.4
numpy===1.21.3
tqdm==4.62.3
matplotlib==3.3.2
pandas==1.3.5
scikit-image==0.17.2

How is it possible to solve this error?

Answer 1

The error comes from the dask package version (see link to github package issue fix ). Thus, it is required to install distributed==2022.01.0.

pip install distributed==2022.01.0
