当我的 jupyter notebook 越来越大时，VScode ssh 连接中断

Question

我正在尝试通过 ssh 远程连接使用 Jupyter notebook。连接和笔记本在小型 jupyter 笔记本上运行良好，但是当我在我的 jupyter 笔记本上添加更多单元格时，首先当我按下执行按钮时开始执行单元格的时间越来越长，然后最终断开连接，我需要每 20 秒重新输入一次密码，因为它一直断开连接。我收到以下错误/终端输出：

我尝试查看此堆栈溢出问题：VSCode Remote SSH Connection Failed 但不明白如何解决我的问题，我对 vscode 和 ssh 连接真的很陌生，我不明白他们在讲述的步骤答案.. 谁能帮帮我？

Answer 1

有一个类似的问题，我没有断开连接，但一切都非常缓慢。在深入研究了一段时间后发现，使用 plt.imshow 渲染图像（尤其是高分辨率图像）会使我的客户端上传大量内容，并且即使在图像被渲染之后，它也会扰乱我的连接。

我认为每次我更改或执行诸如执行单元格之类的操作时，它都会将整个笔记本上传到服务器。由于我的上传速度很差，每次都需要上传一些 MB，这会干扰我的连接，使一切变得缓慢且无响应。

我的解决方案是清除渲染图像的单元格输出。

我猜问题是每次笔记本发生变化时，它都需要整体上传才能更新。这些图像使文件变大了一些 MB 而不是一些 KB，我想任何可以使 .ipynb 文件变大的东西都会导致同样的问题。

Answer 2

能否尝试增加远程机器（wsl 或其他）的内存限制？

有些人遇到了同样的问题。详情可以参考here和here。
