实现Transformers离线使用需要以下步骤:
- 预先下载模型:
from huggingface_hub import snapshot_download
snapshot_download(repo_id="meta-llama/Llama-2-7b-hf", repo_type="model") - 启用离线模式:
Setting environment variables:export HF_HUB_OFFLINE=1
- Load the local model:
model = LlamaForCausalLM.from_pretrained("./path/to/local/directory", local_files_only=True)
Caveats:
- 确保下载完整的模型文件和配置文件
- 模型版本需要与Transformers框架版本兼容
- 首次加载建议在有网络环境下测试
- 大数据量模型(如LLaMA-2)需要足够存储空间
- 生产环境建议定期检查更新
