LightFM .fit() (loss)

[Datchthana1]

Hi,

I am using LightFM with Python 3.12.4.

I can use loss='logistic' without any issue, but when I try to use loss='warp' or loss='bpr', it fails.

I got silently stopped

To try to fix it, I installed the latest version from GitHub using:

pip install git+[https://github.com/daviddavo/lightfm](https://github.com/daviddavo/lightfm)

However, the problem persists.

Could you please advise how to properly enable WARP and BPR losses in this setup?

Environment:

• Python 3.12.4
• LightFM unknown version
• OS: Windows 11

Thanks!

You can use WARP and BPR only on Linux, unfortunately.

Oh, thank you for your information
And warp-kos can only be used on Linux, also?
