pip install transformers教程

直接pip install transformers会报错，报错内容如下：

Collecting safetensors>=0.3.1 (from transformers)
  Using cached safetensors-0.5.2.tar.gz (66 kB)

      Cargo, the Rust package manager, is not installed or is not on PATH.
      This package requires Rust and Cargo to compile extensions. Install it through

重点是Cargo, the Rust package manager, is not installed or is not on PATH这句话，所以可能Rust没有安装，那我们安装Rust，
参考网址，具体步骤：

# 确认一下你的curl是不是用snap安装的
sudo snap list | grep curl
# 如果是，卸载
sudo snap remove curl
# 然后用apt重新安装
sudo apt install curl
# 安装Rust
curl --proto '=https' --tlsv1.2 -sSf https://sh.rustup.rs | sh
# 添加环境变量
source $HOME/.cargo/env
# 测试是否安装成功
rustc -V 

Rust安装成功后再pip install transformers即可
