Question

当我导入skimage时，收到一条奇怪的错误消息，似乎与scikit-image，numpy和dask的版本不匹配问题有关，但是如果我立即尝试再次导入，一切都很好-即

这些dask和numpy版本显然不兼容。有很多关于此的错误报告

https://github.com/scikit-image/scikit-image/issues/3649
https://github.com/scikit-image/scikit-image/issues/3654
https://github.com/scikit-image/scikit-image/issues/3818

解决方案似乎正在更新，所以可以尝试

conda update --no-update-deps dask

为什么第一次导入skimage失败，但是第二次成功？
