This model is for debugging. It is randomly initialized using the config from Qwen/Qwen2.5-72B-Instruct but with smaller size.

Codes:

python

import transformers
import torch
import os
from huggingface_hub import create_repo, upload_folder
import accelerate

save_path = '/tmp/yujiepan/qwen2.5-128k-tiny-random'
repo_id = 'yujiepan/qwen2.5-128k-tiny-random'

os.system(f'rm -rf {save_path}')

    model_id,
    trust_remote_code=True,

config.max_window_layers = 1
config.rope_scaling = {
    "factor": 4.0,
