Reproduction

运行mmlu评估时，results.json中的结果少了一项。 results.json中没课结果只有四个答案，如下：

  "abstract_algebra": {
    "0": "B",
    "1": "C",
    "2": "A",
    "3": "A"
  },
  "anatomy": {
    "0": "D",
    "1": "C",
    "2": "C",
    "3": "B"
  },

mmlu的数据中每个应该有五项： abstract_algebra如下：

Find all c in Z_3 such that Z_3[x]/(x^2 + c) is a field.	0	1	2	3	B
Statement 1 | If aH is an element of a factor group, then |aH| divides |a|. Statement 2 | If H and K are subgroups of G then HK is a subgroup of G.	True, True	False, False	True, False	False, True	B
Statement 1 | Every element of a group generates a cyclic subgroup of the group. Statement 2 | The symmetric group S_10 has 10 elements.	True, True	False, False	True, False	False, True	C
Statement 1| Every function from a finite set onto itself must be one to one. Statement 2 | Every subgroup of an abelian group is abelian.	True, True	False, False	True, False	False, True	A
Find the characteristic of the ring 2Z.	0	3	12	30	A

anatomy如下所示：

What is the embryological origin of the hyoid bone?	The first pharyngeal arch	The first and second pharyngeal arches	The second pharyngeal arch	The second and third pharyngeal arches	D
Which of these branches of the trigeminal nerve contain somatic motor processes?	The supraorbital nerve	The infraorbital nerve	The mental nerve	None of the above	D
The pleura	have no sensory innervation.	are separated by a 2 mm space.	extend into the neck.	are composed of respiratory epithelium.	C
In Angle's Class II Div 2 occlusion there is	excess overbite of the upper lateral incisors.	negative overjet of the upper central incisors.	excess overjet of the upper lateral incisors.	excess overjet of the upper central incisors.	C
Which of the following is the body cavity that contains the pituitary gland?	Abdominal	Cranial	Pleural	Spinal	B

运行的脚本：

python run/eval.py llama3_lora_eval.yaml

run/eval.py简单的套了个run_eval()函数，如下所示：

from llamafactory.eval.evaluator import run_eval
run_eval()

llama3_lora_eval.yaml如下所示：

### model
model_name_or_path: /opt/gfbai/models/Meta-Llama-3-8B-Instruct
adapter_name_or_path: saves/llama3-8b/lora/sft/checkpoint-54

### method
finetuning_type: lora

### dataset
task: mmlu
split: train
template: fewshot
lang: en
n_shot: 5

### output
save_dir: saves/llama3-8b/lora/eval

### eval
batch_size: 2
download_mode: force_redownload

应该是mmlu数据集的脚本有问题 这个文件evaluation/mmlu/mmlu.py中：

def _generate_examples(self, filepath):
    df = pd.read_csv(filepath)
    df.columns = ["question", "A", "B", "C", "D", "answer"]

    for i, instance in enumerate(df.to_dict(orient="records")):
        yield i, instance

改为以下形式就好了

def _generate_examples(self, filepath):
    df = pd.read_csv(filepath, header=None)
    df.columns = ["question", "A", "B", "C", "D", "answer"]

    for i, instance in enumerate(df.to_dict(orient="records")):
        yield i, instance
