Python conda

# Python3 conda

## 安装

```bash

wget https://repo.anaconda.com/miniconda/Miniconda3-latest-Linux-x86_64.sh

sudo bash Miniconda3-latest-Linux-x86_64.sh

conda config --set auto_activate_base false

```

### 多用户使用

安装时，会自动在.bashrc中添加初始化脚本。需要保持有权限访问miniconda3，同时以下二选一

- 执行Shell

```bash

eval "$(/data/service/miniconda3/bin/conda shell.bash hook)"

```

- 手动修改`.bashrc`

```bash

# >>> conda initialize >>>

# !! Contents within this block are managed by 'conda init' !!

__conda_setup="$('/data/service/miniconda3/bin/conda' 'shell.bash' 'hook' 2> /dev/null)"

if [ $? -eq 0 ]; then

    eval "$__conda_setup"

else

    if [ -f "/data/service/miniconda3/etc/profile.d/conda.sh" ]; then

        . "/data/service/miniconda3/etc/profile.d/conda.sh"

    else

        export PATH="/data/service/miniconda3/bin:$PATH"

    fi

fi

unset __conda_setup

# <<< conda initialize <<<

```

## 清华源

## 虚拟环境

```bash

conda list

conda create -n llama python=3.10

conda activate llama

source  deactivate

```

### 虚拟环境改名

先激活，再克隆一个，然后删除旧的

```bash

conda activate modelscope

conda create -n sambert --clone modelscope

conda deactivate

conda remove -n modelscope

```

未验证是否真正需要激活
