Tracking information

REPLACE_ME

Code to reproduce issue

catalog = "model_registry"
schema = "default"
model_name = "psy-ai"
mlflow.set_registry_uri("databricks-uc")
mlflow.register_model(

)

Stack trace

MlflowException: Failed to download the model weights from the HuggingFace hub and cannot register the model in the Unity Catalog.

@vitaliy-sharandin Thanks for reporting this. Could you share your model logging code?

harupy commented 4 months ago

I ran the following code but could not reproduce the error:

%pip install -U git+https://github.com/huggingface/transformers torch accelerate==0.29.3 mlflow

dbutils.library.restartPython()

########

import transformers
import torch

model_id = "meta-llama/Meta-Llama-3-8B-Instruct"
pipeline = transformers.pipeline(
    "text-generation",
    model=model_id,
    model_kwargs={"torch_dtype": torch.bfloat16},
    token="...",
)

import mlflow
import uuid

mlflow.set_registry_uri("databricks-uc")

with mlflow.start_run() as run:
  mlflow.transformers.log_model(pipeline, "model")

mlflow.register_model(
    model_uri=f"runs:/{run.info.run_id}/model",
    name=f"..."
)

vitaliy-sharandin commented 4 months ago

The main difference between our code is that I am first fine-tuning adapters with peft and trying to register the run which has only adapters saved and base model reference without model weights. I have also read MLFLow Transformers guide which specifies that you don't need to use mlflow.transformers.persist_pretrained_model() once you are trying to register model to Unity Catalogue, hence my code has to work as I am trying to do exactly that.

Here is my notebook: https://github.com/vitaliy-sharandin/data_science_projects/blob/master/portfolio/nlp/fine-tuned-llm/psy_ai_mlflow_tracking_deployment.ipynb

harupy commented 4 months ago

Thanks for the notebook! Let me run the notebook and see If I can reproduce the issue.

harupy commented 4 months ago

@vitaliy-sharandin Can you try inserting this code before loading the model to see if it can fix the error?

def get_model_with_peft_adapter(base_model, peft_adapter_path):
    from peft import PeftModel

    return PeftModel.from_pretrained(base_model, peft_adapter_path, offload_folder="offload")

mlflow.transformers.get_model_with_peft_adapter = get_model_with_peft_adapter

Not sure if offload_folder is the only to fix this issue, but want to give it a try.

vitaliy-sharandin commented 4 months ago

It doesn't quite make sense, as I don't have adapters to load pre-model-tuning, so I don't have value for peft_adapter_path obligatory argument.

github-actions[bot] commented 3 months ago

@mlflow/mlflow-team Please assign a maintainer and start triaging this issue.

harupy commented 3 months ago

@vitaliy-sharandin the traceback says get_model_with_peft_adapter is called.

vitaliy-sharandin commented 3 months ago

@harupy Sorry, I have misunderstood your code at first. I did what you've proposed and it led to new error, please check out the notebook.

vitaliy-sharandin commented 3 months ago

@harupy Any updates?
