Start by reproducing the model-loading failure from evaluate/lora.py and trace the calls through lit_llama/model.py, lit_llama/lora.py, and lit_llama/quantization.py. Compare the relevant PyTorch module initialization paths; done means the reported TypeError no longer occurs when loading the model.
