Jupyter平台默認開發的字體為宋體，在高分屏下視覺效果差
在 C:\User\用戶名\.jupyter\custom下面的custom.css中，修改字體
PS:如果沒有這些文件，或者沒有custom這個文件夾，可以手動建立這些文件
在custom.css文本中，添加下面內容：
div.notebook {font-family: Consolas, "Microsoft YaHei Mono", "Microsoft YaHei";}
div.CodeMirror pre {font-family: Consolas, "Microsoft YaHei Mono", "Microsoft YaHei"; font-size: 10pt;}
div.output_area pre {font-family: Consolas, "Microsoft YaHei Mono", "Microsoft YaHei"; font-size: 10pt;}
div.input_prompt {font-family: Consolas, "Microsoft YaHei Mono", "Microsoft YaHei"; font-size: 10pt;}
div.out_prompt_overlay {font-family: Consolas, "Microsoft YaHei Mono", "Microsoft YaHei"; font-size: 10pt;}
div.prompt {font-family: Consolas, "Microsoft YaHei Mono", "Microsoft YaHei"; font-size: 10pt;}
span.cm-comment {font-family: Consolas, "Microsoft YaHei Mono", "Microsoft YaHei" !important; font-style:normal !important;}
code {font-family: Consolas, "Microsoft YaHei Mono", "Microsoft YaHei";}
