加速conda安装程序包——mamba

mamba安装环境速度远大于conda和miniconda。

通过以下方式安装，比conda install mamba -n base -c conda-forge速度快很多。

wget "https://github.com/conda-forge/miniforge/releases/latest/download/Mambaforge-$(uname)-$(uname -m).sh"
bash Mambaforge-$(uname)-$(uname -m).sh -b

如激活环境 conda activate 换成 mamba activate
