Question

我正在学习Bokeh，我想让示例'stock'脚本https://demo.bokehplots.com/apps/stocks生成一个独立的html文件...我添加了以下代码：

from bokeh.embed import components

plots = [corr, ts1, ts2]
script, div = components(plots)
print(script)
print(div)


html = """<!DOCTYPE html>
<html lang="en">
    <head>
        <meta charset="utf-8">
        <title>Bokeh Scatter Plots</title>

        <link rel="stylesheet"  href="http://cdn.pydata.org/bokeh/release/bokeh-0.12.6.min.css"   type="text/css" />
        <script type="text/javascript" src="http://cdn.pydata.org/bokeh/release/bokeh-0.12.6.min.js"></script>

        <!-- COPY/PASTE SCRIPT HERE -->
        {}

    </head>
    <body>
        <!-- INSERT DIVS HERE -->
        {}
    </body>
</html>""".format(script, div)

with open("plotstock.html", "w") as f:
    f.write(html)

位于脚本的底部，这适用于在http://bokeh.pydata.org/en/latest/docs/user_guide/embed.html找到的更简单的示例（没有小部件导入）但是对于库存脚本我得到错误：

散景错误

模型`PreText'不存在。这可能是由于在首次使用之前未注册小部件或自定义模型。**

如果删除对此窗口小部件的引用，我会在下一个窗口小部件中获得相同的错误，即选择窗口小部件...

我可以在散景服务器中运行此脚本，并将数据本地化，但嵌入是问题......

生成的html似乎完整，包含数据和组件部分：

    <head>
        <meta charset="utf-8">
        <title>Bokeh Scatter Plots</title>

        <link rel="stylesheet"   href="http://cdn.pydata.org/bokeh/release/bokeh-0.12.6.min.css"   type="text/css" />

      Bokeh.embed.embed_items(docs_json, render_items);
    });
  };
  if (document.readyState != "loading") fn();
  else document.addEventListener("DOMContentLoaded", fn);
})();

    </body>
</html>

有人能告诉我发生了什么或有任何想法吗？

感谢。

Bokeh小部件的JS文件是单独分发的，因此页面只会在实际使用它们时产生加载它们的成本。您需要按照in the documentation所述的CDN添加bokeh-widgets：

<link
    href="http://cdn.pydata.org/bokeh/release/bokeh-widgets-0.12.6.min.css"
    rel="stylesheet" type="text/css">    
<script src="http://cdn.pydata.org/bokeh/release/bokeh-widgets-0.12.6.min.js"></script>
