Unable to import Lightgbm in Jupyter notebook on Windows 10

Question

I am able to install Lightgbm using the command below:

pip install --trusted-host pypi.org --trusted-host pypi.python.org --trusted-host files.pythonhosted.org lightgbm

I am able to see it installed by using Conda list as well.

However,after that I am unable to import the package into Jupyter notebook.

I am getting the below error.

import lightgbm

AttributeError: module 'pandas.core.strings' has no attribute 'StringMethods'`

I tried the above methods but in vain.There are multiple other error lines as well indicating dask.dataframe error which I am unable to find out the method to cure.

Answer 1

As described in microsoft/LightGBM#5379, dask<2023.2.0 is not compatible with pandas>=2.0.

Though you haven't included details like the output of conda-env export or pip freeze, I strongly suspect you have such versions of those libraries.

Either remove dask from your environment ...

pip uninstall --yes \
    dask

... or upgrade it and distributed to a newer version

pip install \
    'dask>2023.3.2' \
    'distributed>2023.3.2'

After doing one of those, restart your notebook's kernel, and you should be able to import lightgbm without facing this issue.

import lightgbm
