Cannot Start Jupyter IPython Notebook Kernel
问题
我正在使用VSCode的Jupyter Notebooks。
我在启动Python（Sagemath）内核时遇到问题。在VSCode中运行单元格时，出现以下错误文本：
无法启动内核。
未知选项--python
用法：/root/anaconda3/envs/sage/bin/python [选项] ... [-c cmd | -m mod | file | -] [arg] ...
尝试 `python -h` 以获取更多信息。
查看Jupyter日志以获取更多详细信息。
这是日志文件中的一部分：
警告 16:18:12.373：内核错误，上下文 = 启动 [ap [错误]：内核已停止运行。错误：未知选项--python

查看了其他类似的内核启动问题，但抛出的错误不同（没有'unknown option --python'），明显实施的解决方案也不起作用。
请让我知道是否需要更多信息以提供帮助！

I'm using Jupyter Notebooks from VSCode.
I'm having issues starting my Python (Sagemath) Kernel. The error text (when running the cell in VSCode) is as follows:

Took a look at other similar kernel start problems, but the errors thrown were different (NOT one with 'unknown option --python', and the solutions implemented obviously did not work.
Please let me know if you need any more information to help!
