@cebtenzzre . Great, I did not see those changes, and this change was intended to be a quick work-around until tied-weights are more properly supported, which sounds like is happening. I will look at those changes. |
This is to support model configurations with "tie_word_embeddings" set to true.

@cebtenzzre, Change updated in llama.cpp, with LLAMA tied-weights now being similar to other tied-weights. |

This supports model configurations with "tie_word_embeddings", by using the embd_tokens weights if output/lm_head weights are missing (as they will be when weights are tied).
With this change, a tied model like the following can be converted to gguf.
