【candle】(2):使用hf-mirror镜像下载TheBloke/Llama-2-7B-GGML的q4
默认的安装模式:
curl --proto '=https' --tlsv1.2 -sSf https://sh.rustup.rs | sh
https://forge.rust-lang.org/infra/other-installation-methods.html
https://static.rust-lang.org/dist/rust-1.74.1-x86_64-unknown-linux-gnu.tar.gz
wget https://static.rust-lang.org/dist/rust-1.74.1-x86_64-unknown-linux-gnu.tar.gz
tar -zxf rust-1.74.1-x86_64-unknown-linux-gnu.tar.gz
cd rust-1.74.1-x86_64-unknown-linux-gnu/
./install.sh --prefix=/root/autodl-tmp/rust --without=rust-docs
这样就可以将 rust 安装到其他目录了:
同时不要安装 rust-docs 有 700 多MB ,实在是没有用。
./install.sh --list-components
# Available components
* rustc
* rust-std-x86_64-unknown-linux-gnu
* rust-docs
* rust-docs-json-preview
* rust-demangler-preview
* cargo
* rustfmt-preview
* rls-preview
* rust-analyzer-preview
* llvm-tools-preview
* clippy-preview
* rust-analysis-x86_64-unknown-linux-gnu
然后执行安装即可:
./install.sh --prefix=/root/autodl-tmp/rust --without=rust-docs
# 安装完成,设置好 PATH 路径:
export PATH=/root/autodl-tmp/rust/bin:$PATH
# 执行 rustc 就可以生效了:
可以执行 rust 命令了:
#设置学术加速,不再区分不同地区
# 设置hf 路径:
export HF_HOME=/root/autodl-tmp/hf_cache
# 下载项目
git clone https://github.com/huggingface/candle.git
cd candle
# 执行一个简单的demo
cargo run --example quantized
然后就是漫长的下载库:
Downloaded ttf-parser v0.15.2
Downloaded zerofrom v0.1.3
Downloaded zstd-safe v6.0.6
Downloaded anstream v0.6.5
Downloaded approx v0.5.1
Downloaded bitflags v1.3.2
Downloaded bytemuck v1.14.0
Downloaded bytes v1.5.0
Downloaded wav v1.0.0
Downloading 81 crates, remaining bytes: 128.3 KB
pip3 install huggingface_hub
然后使用模型下载脚本:
download_model.py :
# 设置镜像
# export HF_ENDPOINT="https://hf-mirror.com"
import os
os.environ['HF_ENDPOINT'] = 'https://hf-mirror.com'
from huggingface_hub import snapshot_download
# 下载第一个模型
snapshot_download(repo_id="TheBloke/Llama-2-7B-GGML", allow_patterns=["llama-2-7b.ggmlv3.q4_0.bin"])
# 下载第二个模型
snapshot_download(repo_id="hf-internal-testing/llama-tokenizer")
# 设置hf home 目录,防止下载到其他目录,磁盘满了。
export HF_HOME=/root/autodl-tmp/hf_cache
# 执行下载方法:
python3 download_model.py
下载速度还可以:

还可以使用 https://aliendao.cn/#/ 进行加速下载。

My favorite theorem is 0 (
zero). It's just a random

还有34b模型,但是没有测试。
使用candle 可以运行大模型了,可以运行 yi-6b的模型,使用镜像下载成功。
candle目前支持的模型还不多,但是未来会慢慢流行起来的。
提前做好学习准备。
