Description
/home/admin188/AI/kohya_ss/sd-scripts/library/sdxl_lpw_stable_diffusion.py:975: RuntimeWarning: invalid value encountered in cast
images = (images * 255).round().astype("uint8")
steps: 32%|██████ | 640/2000 [34:52<1:14:06, 3.27s/it, Average key norm=nan, Keys Scaled=980, avr_loss=nan]
How could I figure the bug? I've no idea how to trace it.

Research direction
Start at /home/admin188/AI/kohya_ss/sd-scripts/library/sdxl_lpw_stable_diffusion.py around line 975 and trace where the image values, average key norm, and loss become NaN. Reproduce the warning, identify the upstream source of the invalid values, and document or fix the behavior once the cause is confirmed.
