方法一：用于使用 aria2/wget+git 下载 Huggingface 模型和数据集的 CLI 工具

来自https://gist.github.com/padeoe/697678ab8e528b85a2a7bddafea1fa4f。

使用方法：将hfd.sh拷贝过去，然后参考下面的参考命令，下载数据集或者模型

🤗Huggingface 模型下载器

考虑到官方 huggingface-cli 缺乏多线程下载支持，以及错误处理不足在 hf_transfer 中，这个命令行工具巧妙地利用 wget 或 aria2 来处理 LFS 文件，并使用 git clone 来处理其余文件。

特点

⏯️ 从断点恢复：您可以随时重新运行它或按 Ctrl+C。
🚀 多线程下载：利用多线程加速下载过程。
🚫 文件排除：使用--exclude或--include跳过或指定文件，为具有重复格式的模型（例如，*.bin或*.safetensors）节省时间）。
🔐 身份验证支持：对于需要 Huggingface 登录的门控模型，请使用 --hf_username 和 --hf_token 进行身份验证。
🪞 镜像站点支持：使用“HF_ENDPOINT”环境变量进行设置。
🌍代理支持：使用“HTTPS_PROXY”环境变量进行设置。
📦 简单：仅依赖git、aria2c/wget。

Usage

首先，下载 hfd.sh 或克隆此存储库，然后授予脚本执行权限。

chmod a+x hfd.sh

为了方便起见，您可以创建一个别名

alias hfd="$PWD/hfd.sh"

使用说明：

$ ./hfd.sh -h
Usage:
  hfd <repo_id> [--include include_pattern] [--exclude exclude_pattern] [--hf_username username] [--hf_token token] [--tool aria2c|wget] [-x threads] [--dataset] [--local-dir path]

Description:
  Downloads a model or dataset from Hugging Face using the provided repo ID.

Parameters:
  repo_id        The Hugging Face repo ID in the format 'org/repo_name'.
  --include       (Optional) Flag to specify a string pattern to include files for downloading.
  --exclude       (Optional) Flag to specify a string pattern to exclude files from downloading.
  include/exclude_pattern The pattern to match against filenames, supports wildcard characters. e.g., '--exclude *.safetensor', '--include vae/*'.
  --hf_username   (Optional) Hugging Face username for authentication. **NOT EMAIL**.
  --hf_token      (Optional) Hugging Face token for authentication.
  --tool          (Optional) Download tool to use. Can be aria2c (default) or wget.
  -x              (Optional) Number of download threads for aria2c. Defaults to 4.
  --dataset       (Optional) Flag to indicate downloading a dataset.
  --local-dir     (Optional) Local directory path where the model or dataset will be stored.

Example:
  hfd bigscience/bloom-560m --exclude *.safetensors
  hfd meta-llama/Llama-2-7b --hf_username myuser --hf_token mytoken -x 4
  hfd lavita/medical-qa-shared-task-v1-toy --dataset

下载模型：

hfd bigscience/bloom-560m

下载模型需要登录

从https://huggingface.co/settings/tokens获取huggingface令牌，然后

hfd meta-llama/Llama-2-7b --hf_username YOUR_HF_USERNAME_NOT_EMAIL --hf_token YOUR_HF_TOKEN

下载模型并排除某些文件（例如.safetensors）：

hfd bigscience/bloom-560m --exclude *.safetensors

使用 aria2c 和多线程下载：

hfd bigscience/bloom-560m

输出：
下载过程中，将显示文件 URL：

$ hfd bigscience/bloom-560m --tool wget --exclude *.safetensors
...
Start Downloading lfs files, bash script:

wget -c https://huggingface.co/bigscience/bloom-560m/resolve/main/onnx/decoder_model.onnx
...

# 安装包
apt update
apt-get install aria2
apt-get install iftop
apt-get install git-lfs 
#参考命令
bash /xxx/xxx/hfd.sh mmaaz60/ActivityNet-QA-Test-Videos --tool aria2c -x 16 --dataset --local-dir /xxx/xxx/ActivityNet
