Do you wish to update your shell profile to automatically initialize conda?
This will activate conda on startup and change the command prompt when activated.
If you'd prefer that conda's base environment not be activated on startup,
   run the following command when conda is activated:

conda config --set auto_activate_base false

You can undo this by running `conda init --reverse $SHELL`? [yes|no]
[no] >>> yes

Thank you for installing Miniconda3!

重启bash并测试：

安装pytorch + cuda：

conda create -n sd python=3.10

pip3 install torch torchvision torchaudio --index-url https://download.pytorch.org/whl/cu121 -i http://mirrors.aliyun.com/pypi/simple/ --trusted-host mirrors.aliyun.com

WARNING: Running pip as the 'root' user can result in broken permissions and conflicting behaviour with the system package manager, possibly rendering your system unusable.It is recommended to use a virtual environment instead: https://pip.pypa.io/warnings/venv. Use the --root-user-action option if you know what you are doing and want to suppress this warning.

验证pytorch环境：

import torch
torch.cuda.is_available()

安装jupyter notebook:

/root/miniconda3/envs/sd/bin/pip3 install jupyter -i http://mirrors.aliyun.com/pypi/simple/ --trusted-host mirrors.aliyun.com

启动jupyter notebook：

jupyter notebook --allow-root
