Describe the bug

This happens when i run openllm. I am using a fresh ubutnu install with fresh venv running.

To reproduce

1.) Create venv 2.) pip install openllm 3.) Run: OPENLLMDEVDEBUG=3 openllm start ../text-generation-webui/models/TheBloke_Mistral-7B-Instruct-v0.2-AWQ --quantize awq 3.1) Run: OPENLLMDEVDEBUG=3 openllm start microsoft/phi-2 4.) Error

Logs

Make sure to check out '../text-generation-webui/models/TheBloke_Mistral-7B-Instruct-v0.2-AWQ' repository to see if the weights is in 'safetensors' format if unsure.
Tip: You can always fallback to '--serialisation legacy' when running quantisation.
It is recommended to specify the backend explicitly. Cascading backend might lead to unexpected behaviour.

have you solved this? I'm getting the same error

[CHesketh76]

Nope, not using OpenLLM and switching to vLLM was my only fix

You just need to pass a backend TRUST_REMOTE_CODE=True openllm start microsoft/phi-2 --backend pt
