Originally assigned to: @joshyan1 on GitHub.

What is the issue?

When quantizing a model with ollama create -q, unknown model architecture errors are not properly bubbled up. E.g. from the logs:

llama_model_loader: - type  f32:  121 tensors
llama_model_loader: - type  f16:  162 tensors
llama_model_quantize: failed to quantize: unknown model architecture: 'chatglm'

User error:

% ollama create -f Modelfile -q q4_0 test
transferring model data 
quantizing F16 model to Q4_0 
Error: llama_model_quantize: 1
