The example here in these example scripts appears to be misleading, as it in peft_config, they show

target_modules = ['k_proj', 'q_proj', 'v_proj', 'o_proj', 'gate_proj', 'down_proj', 'up_proj'],

which is incorrect based on the model's architecture.

It should be target_modules = ['qkv_proj', 'o_proj', 'gate_up_proj', 'down_proj'],
