model.set_attn_implementation("eager")
print(model.config._attn_implementation)

Traceback (most recent call last):

It would be very nice to include this in the v5. This caused test failures for my work on #42564 for ChineseCLIP and AyaVision, likely as those modeling files have characters that the default Windows cp1252 encoding doesn't recognize.

Can we also patch set experts at the same time? bf0ae70
