[Bug] extract_non_reasoning_content error when predict is null

[simplew2011]

Prerequisite

• I have searched Issues and Discussions but cannot get the expected help.
• The bug has not been fixed in the latest version.

Type

I'm evaluating with the officially supported tasks/models/datasets.

Environment

version 0.4.1

Reproduces the problem - code/configuration sample

from mmengine.config import read_base
from opencompass.models import OpenAISDK

with read_base():
    from opencompass.configs.datasets.math.math_500_gen import math_datasets



# pip install math_verify latex2sympy2_extended
# pip install langdetect
# opencompass eval_gsm8k.py
# opencompass opencompass/eval_ds3.py

datasets = math_datasets

from opencompass.utils.text_postprocessors import extract_non_reasoning_content

models = [
    dict(
        abbr='deepseek-r1-h800-32768',
        type=OpenAISDK,
        path='/root/.cache/huggingface',
        openai_api_base=['http://10.24.9.4:8000/v1'],
        # tokenizer_path='/opt/weights/DeepSeek-V3',
        key=
        'token-abc123',
        # meta_template=api_meta_template,
        # query_per_second=2,
        max_out_len=16384,
        max_seq_len=32768, # 32768
        temperature=0.6,
        batch_size=16,
        pred_postprocessor=dict(type=extract_non_reasoning_content),
        retry=10
        ),
]

Reproduces the problem - command or script

test math-500 using deepseek-r1 model

How do you deploy the api server [http://10.24.9.4:8000/v1]? Can any-curl-command get the correct answer?

[liushz]

Can you show some responses without the pred_postprocessor.

Hi @simplew2011, you can troubleshoot by removing the pred_postprocessor and see if you get any predictions that way. If you do, it is likely due to the postprocessor function not extracting the content correctly. If you don't, check that your api server returns model responses as expected.
