spyder 和远程 ssh python 解释器

Question

我有一个 ubuntu 服务器，我可以在其中使用 ssh 连接运行 python 解释器。 我想将解释器链接到我的一个 IDE。

spyder 是否支持远程 ssh 解释器？如果不是，什么是可能的免费替代方案？

编辑： 使用新版本的 spyder 似乎可以连接到远程 shell。 但是当我尝试连接时收到此错误

Spyder 的开发版本支持连接到远程 IPython 内核（它可以是 IPython notebook 的内核）。这个功能将成为 Spyder 的下一个次要版本 2.3.1 的一部分，希望在几周内。您可以通过从源代码运行 Spyder 来使用它。

编辑：关于您的编辑（错误解码连接信息文件）。您的连接文件似乎不是有效的 json。能给我们介绍一下内容吗？通常，它应该是这样的：
