Description

I got the following error when running model Imported from GGUF which is generated from the model fine-tuned with LoRA.

Error: llama runner process has terminated: GGML_ASSERT(src1t == GGML_TYPE_F32) failed

The following are commands used

mlx_lm.lora --train --model meta-llama/Llama-3.2-1B --data ~/Projects/AI/data --iters 1000

mlx_lm.generate --model meta-llama/Llama-3.2-1B --adapter-path ./adapters --prompt "What is biomolecule?"

mlx_lm.fuse --model meta-llama/Llama-3.2-1B --adapter-path ./adapters --export-gguf

Create Modelfile
FROM ./fused_model/ggml-model-f16.gguf

ollama create example -f Modelfile

ollama run example

Research direction

Reproduce the issue with the listed mlx_lm.lora, mlx_lm.generate, mlx_lm.fuse, and Ollama commands using the referenced GGUF model. Start from the GGML_ASSERT in ggml-metal.m:1080 and compare the exported model with the input expected by the Ollama runner. Done means identifying the incompatible tensor or export step and confirming that the resulting model runs without the assertion.
