How to get feature importances

[yuhai-china]

Hey,

LightGBM is greate, I try to use it for several datasets, but I cannot get feature importance after training.
How can I enable to output feature importance after training?

Thanks

feature importance will write to model file automatically. you can check the model file.

[yuhai-china]

LightGBM_model.txt

train.conf.txt

However, I cannot find feature importance from the model file as attached, anything wrong?

Thanks
