import dask.dataframe as ddpip install dask

import mars.dataframe as mdpip install pymars
import datatable as dtpip install datatable
是我安装方法错了吗？

翻译一下不就好了嘛
不是pip的问题，是你安装的这些包本身有问题

好霉啊，需要的三个包都没安装成功

我也输了不行啊

看到你的文件路径里有中文，这可能是问题的原因。

同感，直接用原Python包吧，不要用venv虚拟环境了

leadjrs 发表于 2022-9-12 10:02

换个python版本试一下最好可以看一下你要安装的那3个包最高支持到哪个python版本

应该是你使用的虚拟环境某些文件被删了，把原来的虚拟环境删了建新的
