在 Python 3.6 中导入库“modin”时出错

Question

import modin.pandas as pd

I am importing modin.pandas library in my windows 10 machine but getting error

"AttributeError: module 'ray' has no attribute 'utils'"

Anything missed while installing modin library?

Answer 1

"AttributeError: module 'ray' has no attribute 'utils'"

It looks like, you should be able to fix the issue if you just install the 1.1 version of ray, by doing the following:

pip install ray==1.1

The modin.pandas creators haven't release support for versions of ray greater then 1.1.

Here is the discussion thread on github: https://github.com/modin-project/modin/issues/3059

Answer 2

Check which version of ray you have; ray.utils used to be called ray.experimental .

You'll either need to upgrade version of the module you're using that has ray as a dependency (meaning the module currently uses the out-of-date version of ray ) , or downgrade the version of the ray (to be compatible with the module you're using) .

Answer 3

I also had the same issue. For me I uninstalled the existing modin and ray package from my instance and then restarted the kernal and then used the following command:

pip install modin[ray]

It then worked for me. If you are running it in google Colab you can find more information here .
