我有一个大型数据源,我需要在我的机器上计算并与其他用户共享,大约每5分钟更新一次 . 更简单的解决方案是我的机器上的散景服务器,他们可以连接到该服务器以查看数据 .

当我尝试运行散景服务器时,出现以下错误:

RuntimeError: Failed to push document: AttributeError("'PropertyValueList' object has no attribute '_owners'",)

我认为这是我如何运行它,我开始设置服务器:

python -m bokeh serve

然后我从散景网站(http://bokeh.pydata.org/en/0.11.1/docs/user_guide/server.html#userguide-server)编译并运行以下示例:

import numpy as np
from numpy import pi

from bokeh.client import push_session
from bokeh.driving import cosine
from bokeh.plotting import figure, curdoc

x = np.linspace(0, 4*pi, 80)
y = np.sin(x)

p = figure()
r1 = p.line([0, 4*pi], [-1, 1], color="firebrick")
r2 = p.line(x, y, color="navy", line_width=4)

# open a session to keep our local document in sync with server
session = push_session(curdoc())

@cosine(w=0.03)
def update(step):
    r2.data_source.data["y"] = y * step
    r2.glyph.line_alpha = 1 - 0.8 * abs(step)

curdoc().add_periodic_callback(update, 50)

session.show() # open the document in a browser

session.loop_until_closed() # run forever
