Question

我正在尝试 运行 简单的 test script of skimage for superpixels segmentation。然而，当我执行代码（python -m src）时，我得到了这个错误：

我的 conda 环境是从这个 requirements.txt 文件安装的：

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

如何解决这个错误？

Answer 1

似乎错误来自 dask 软件包版本（参见 link to github package issue fix）。 因此需要安装distributed=2022.01.0.

pip install distributed=2022.01.0
