散景服务运行,但无法访问浏览器

Question

我已经安装了bokeh并从官方页面(http://bokeh.pydata.org/en/latest/docs/user_guide/server.html)下载了myapp.py,如下所示.

# myapp.py

from random import random

from bokeh.layouts import column
from bokeh.models import Button
from bokeh.palettes import RdYlBu3
from bokeh.plotting import figure, curdoc

# create a plot and style its properties
p = figure(x_range=(0, 100), y_range=(0, 100), toolbar_location=None)
p.border_fill_color = 'black'
p.background_fill_color = 'black'
p.outline_line_color = None
p.grid.grid_line_color = None

# add a text renderer to our plot (no data yet)
r = p.text(x=[], y=[], text=[], text_color=[], text_font_size="20pt",
           text_baseline="middle", text_align="center")

i = 0

ds = r.data_source

# create a callback that will add a number in a random location
def callback():
    global i

    # BEST PRACTICE --- update .data in one step with a new dict
    new_data = dict()
    new_data['x'] = ds.data['x'] + [random()*70 + 15]
    new_data['y'] = ds.data['y'] + [random()*70 + 15]
    new_data['text_color'] = ds.data['text_color'] + [RdYlBu3[i%3]]
    new_data['text'] = ds.data['text'] + [str(i)]
    ds.data = new_data

    i = i + 1

# add a button widget and configure with the call back
button = Button(label="Press Me")
button.on_click(callback)

# put the button and plot in a layout and add to the document
curdoc().add_root(column(button, p))

在终端中,我然后执行:

bokeh serve --show myapp.py

我明白了:

2017-04-17 13:24:50,576 Starting Bokeh server version 0.12.5
2017-04-17 13:24:50,581 Starting Bokeh server on port 5006 with applications at paths ['/myapp']
2017-04-17 13:24:50,581 Starting Bokeh server with process id: 700

我的浏览器(尝试使用Safari和Chrome)然后弹出一个新选项卡,用于http:// localhost:5006/myapp,但该页面无法加载.它在进度条上停留在大约10%,并且永远不会改变"等待本地主机......".我已经安装了散景网站上列出的依赖项.我错过了什么？

顺便说一句,我正在运行OS X 10.12.4.我也尝试过在Windows机器上遇到完全相同的问题.在我的网络浏览器的控制台中没有任何显示,它只是一直"等待127.0.0.1".如果我关闭浏览器并尝试重新打开页面,我会在终端中看到一个"302 GET"请求,但就是这样.

我希望你们都能解决这个问题:

Bokeh服务器与tornado = 4.5不兼容

Tornado 4.5(几天前发布)进行了一项更改,导致Bokeh服务器无法正常运行.对此的修复是在master中,将在下一个0.12.6版本中.但该修复程序也可在最新的开发版中使用.您的直接选择是:

• 将龙卷风降级至<= 4.4.2,或
• 安装Bokeh> = 0.12.6
