ValueError: Target modules {'c_proj', 'w1', 'c_attn', 'w2'} not found in the base model. Please check the target modules and try again.

Inizia da src/pefts/merge_base_and_lora_to_hf.py alla riga 82 e segui la chiamata a PeftModel.from_pretrained che genera l'errore. Confronta il modello di base e i moduli target dell'adapter, inclusi c_proj, w1, c_attn e w2; il lavoro è completato quando i pesi Qwen possono essere uniti senza il target-modules ValueError.

Scritto dal modello di indicizzazione a partire dal testo della issue.
