Using mlx lora.py with llama-2-13b and mixtral-8x7b

Hello World! I am attempting to train my models on my own data. If I run the lora.py command using the 7b models from mistral or llama, it works fine. As soon as I upgrade to the larger models, I get an error File “/Users/conleysa/AI/MLX/mlx_venv/lib/python3.11/site-packages/mlx/nn/layers/base.py”, line 211, in load_weights
raise ValueError(f"Received parameters not in model: {extras}.")

I am using the Apple mlx python API on an M3 Max with 128GB RAM.

I get the exact same error running convert.py. The commands I have tried are:
python convert.py --hf-path mistralai/Mixtral-8x7B-Instruct-v0.1 -q
python lora.py --model mistralai/Mixtral-8x7B-Instruct-v0.1 --train --batch-size 1 --lora-layers 4

Same error both times. I’ll post the full error below but it’s ugly.
