无法为Dask安装tlz模块Python

Question

在Windows 10 Python 3.7.9（空闲）上，当我使用Dask时，我首先调用delayed：

pip install delayed

然后我导入：from dask import delayed，但有一个错误：

Traceback (most recent call last): File "<pyshell#12>", line 1, in from dask import delayed File "C:\Python379\lib\site-packages\dask\delayed.py", line 7, in from tlz import curry, concat, unique, merge ModuleNotFoundError: No module named 'tlz'

我试图单独安装模块，但只安装了concat、unique和merge

Answer 1

在windows上似乎也需要运行：pip install tornado==4.5.1 distributed==1.21 dask-ml[complete]，正如this coment所指

此外，您还需要将延迟导入为：

from dask.delayed import delayed
