【问题描述】：
我正在学习 Bokeh，我想让示例 'stocks' 脚本 https://demo.bokeh.org/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.bokeh.org/bokeh/release/bokeh-0.12.6.min.css" type="text/css" />
<script type="text/javascript" src="http://cdn.bokeh.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)
在脚本的底部，这适用于在http://docs.bokeh.org/en/latest/docs/user_guide/embed.html 找到的一个更简单的示例（没有小部件导入），但对于股票脚本我得到错误：
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。**
如果我删除对这个小部件的引用，我会为下一个小部件（选择小部件）收到相同的错误...
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 看起来确实很完整，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.bokeh.org/bokeh/release/bokeh-0.12.6.min.css" type="text/css" />

谁能告诉我发生了什么或有什么想法？
谢谢。
