anaconda/bin/LightGBM  master ✔

When I code:

import lightgbm as lgm

Got an error:

ImportError: No module named lightgbm

How to solve this....I'm so sad.XD

Answer 1

Make sure you go through the lightgbm installation guides . Then try conda list to check if lightgbm is in the installed package list.

If the module is not installed using conda or pip , it's possible that your module is not add to the python path.

You can either config it manually by modifying the env in the beginning of your Python session, or use jupyter notebook/Python just under the module directory.

Answer 2

enter image description here Create a new environment in conda according to requirements shown in lightgbm and than create a environment list in jupyter and use according to your package by changing in kernel setting it will work fine.

How to create new env?

conda create --n py37_64 python=3.7 

Also download according 32 bit or 64 bit for lightgbm 64 bit is used for that:

config --env --set subdir win--64

and activate particular env here it is py37_64 so command will be:

activate py37_64

and install lightgbm:

 pip install lightgbm

Now see the magic and use this env in your jupyter notebook.

conda install nb_conda

For using this kernels in notebook you have to deactivate env and activate it again

Now see your notebook

Here you can see in image im actually using this now you can switch kernels according to your requirement.
