Previously,
token_embd.weight
was quantized likeoutput.weight
when the model architecture did not containoutput.weight
at all.This did not work properly for models with an optional
output.weight
tensor.Now, the presence of
output.weight
is checked and its absence is assumed to mean thattoken_embd.weight
should be quantized in the same way asoutput.weight
would have been.
