3.参考

参考 csdn

二.服务器信息

1.GPU 服务器

• GPU 服务器自带 CUDA 安装(前提是需要勾选上)
• CUDA 需要选择大于 11.3 的版本
• 登录服务器后会自动安装 GPU 驱动

2.CUDA 安装

3.登录信息

删除指定主机的秘钥:

ssh-keygen -R 47.107.139.237

ssh-keygen -R 47.107.139.237 的作用是从 known_hosts 文件中删除指定主机的密钥。known_hosts 文件是 SSH 用来存储已知主机的公钥的文件。通常情况下，当你首次连接到一个主机时，SSH 会将该主机的公钥添加到 known_hosts 文件中，以后的连接中会验证主机的公钥是否匹配，以确保连接的安全性。使用 -R 选项可以从该文件中删除指定主机的条目，这在你知道主机的密钥可能已经发生变化或需要清理旧密钥时很有用。

登录信息:

#
sshpass -p xxxxx ssh -A -g root@47.107.139.237

# 给豪哥的
47.107.139.237

# torch版本---github要求的
pip install torch==1.9.0+cu111 torchvision==0.10.0+cu111 torchaudio==0.9.0 -f https://download.pytorch.org/whl/torch_stable.html

# 指定cuda==11.3时,pytorch的版本pytorch==1.12.1
pip install torch==1.12.0+cu113 torchvision==0.13.0+cu113 torchaudio==0.12.0 -f https://download.pytorch.org/whl/torch_stable.html

版本对应关系:

版本关系

当已经装好torch包时，pip install torchvision torchaudio会自动寻找对应的版本安装。

6.网络测试

# 会用到的网站
