I would like to know how I can obtain, if possible, the MSE and MAE metrics of the lightFM model in python

Question

To evaluate the model, I need to obtain the lightFM model error metrics, specifically the MAE and MSE metrics.

I have found extensive literature on obtaining error metrics for models implemented with scikit-learn and tensorflow libraries, but in the case of the lightFM model I don't know how I could obtain these metrics.
