Harness Evaluation

Harness evaluation allows users to eaisly get accuracy on various datasets. Here we have enabled harness evaluation with IPEX-LLM under Open LLM Leaderboard settings. Before running, make sure to have ipex-llm installed.

Install Harness

git clone https://github.com/EleutherAI/lm-evaluation-harness.git
cd lm-evaluation-harness
git checkout b281b09
pip install -e .

Run

run python run_llb.py. run_llb.py combines some arguments in main.py to make evaluations easier. The mapping of arguments is defined as a dict in llb.py.

Evaluation on CPU

export IPEX_LLM_LAST_LM_HEAD=0

python run_llb.py --model ipex-llm --pretrained /path/to/model --precision nf3 sym_int4 nf4 --device cpu --tasks hellaswag arc mmlu truthfulqa --batch 1 --no_cache

Evaluation on Intel GPU

export IPEX_LLM_LAST_LM_HEAD=0

python run_llb.py --model ipex-llm --pretrained /path/to/model --precision nf3 sym_int4 nf4 --device xpu --tasks hellaswag arc mmlu truthfulqa --batch 1 --no_cache

Evaluation using multiple Intel GPU

export IPEX_LLM_LAST_LM_HEAD=0

python run_multi_llb.py --model ipex-llm --pretrained /path/to/model --precision nf3 sym_int4 nf4 --device xpu:0,2,3 --tasks hellaswag arc mmlu truthfulqa --batch 1 --no_cache

Taking example above, the script will fork 3 processes, each for one xpu, to execute the tasks.

Results

We follow Open LLM Leaderboard to record our metrics, acc_norm for hellaswag and arc_challenge, mc2 for truthful_qa and acc for mmlu. For mmlu, there are 57 subtasks which means users may need to average them manually to get final result.

Known Issues

1.Detected model is a low-bit(sym int4) model, please use `load_low_bit` to load this model

Harness evaluation is meant for unquantified models and by passing the argument --precision can the model be converted to target precision. If you load the quantified models, you may encounter the following error:

********************************Usage Error********************************
Detected model is a low-bit(sym int4) model, Please use load_low_bit to load this model.

However, you can replace the following code in this line:

AutoModelForCausalLM.from_pretrained = partial(AutoModelForCausalLM.from_pretrained,**self.bigdl_llm_kwargs)

to the following codes to load the low bit models.

class ModifiedAutoModelForCausalLM(AutoModelForCausalLM): 
    @classmethod
    def load_low_bit(cls,*args,**kwargs):
        for k in ['load_in_low_bit', 'device_map', 'max_memory', 'load_in_8bit','load_in_4bit']: 
        kwargs.pop(k)
    return super().load_low_bit(*args, **kwargs)

AutoModelForCausalLM.from_pretrained=partial(ModifiedAutoModelForCausalLM.load_low_bit, *self.bigdl_llm_kwargs)

2.Please pass the argument `trust_remote_code=True` to allow custom code to be run.

lm-evaluation-harness doesn't pass trust_remote_code=true argument to datasets. This may cause errors similar to the following one:

RuntimeError: Job config of task=winogrande, precision=sym_int4 failed. 
Error Message: The repository for winogrande contains custom code which must be executed to correctly load the dataset. You can inspect the repository content at https://hf.co/datasets/winogrande.
please pass the argument trust_remote_code=True to allow custom code to be run.

Please refer to these:

You have to manually run export HF_DATASETS_TRUST_REMOTE_CODE=1 to solve the problem.
