总结：MobaXterm远程连接autodl服务器，在MobaXterm上利用X11转发使pyqt可视化页面在自己的电脑上展现出来。

1. 官网下载MobaXterm

MobaXterm free Xserver and tabbed SSH client for Windows，我认为这个比pycharm专业版连接autodl服务器更加好用。pycharm需要考虑同步，MobaXterm不需要点那么多同步设置。在MobaXterm上操作也比autodl上的jupyterlab好操作。

2. 在autodl上租服务器

一般一个小时1.6-2r。这里注意显存大小能否支撑起模型的参数量（关于这个具体是怎么判断的，我还不会，会了再补充）我租的是4090D，建议起个早租卡，现在是晚上八点，我刚才创建新的实例租卡租不了，但是早上八点我看有富余。

镜像可以选择社区镜像，我用的是V3版本，它自带了1.5B的模型。deepseek-ai/DeepSeek-R1/DeepSeek-R1: 【一键聊天，多维研究】 DeepSeek-R1，目前位居全球大模型竞技榜前三，性能对标OpenAIo1正式版。深度求索（DeepSeek）公司在2025年1月20日发布的最新模型！ - CG

3. MobaXterm连接autodl服务器

4. 我下载了7B的模型，注意下面下载到autodl-tmp目录中。

conda activate torch_env
export HF_ENDPOINT=https://hf-mirror.com
huggingface-cli download deepseek-ai/DeepSeek-R1-Distill-Qwen-7B --local-dir /root/autodl-tmp/DeepSeek-R1-Distill-Qwen-7B --resume-download

7B模型运行相比1.5那个应该只改了模型路径，运行后可以在终端与模型对话，输入exit退出：

文件名：deepseek_multichat-7B.py 

终端运行输入：python deepseek_multichat-7B.py

5. 接下来是最让我头疼的pyqt图形化页面显示。

autodl上是不能直接运行出图形化页面的。可以解决有两种方式：第一种方法：模型利用flask打包成api接口，然后在自己电脑上访问这个接口，在自己电脑上显示出来图形化页面；第二种方法：利用X11转发功能，在autodl上运行图形化页面程序，然后在自己电脑上显示。我用的第二种方法，第一种方法是问了师兄，这个还没尝试，之后尝试了再记录。

一开始用Xlaunch不行，MobaXterm就不需要那么多配置。

如果X11 Forward 显示红叉 可以参考：MobaXterm连接服务器，通过x11 Forwarding实现图形可视化（记录个人学习过程）_mobaxterm x11-CSDN博客

最重要的应该是那个X11UseLocalhost no，我用的pyqt，不需要localhost，也设置了no
