Развертывание на сервере Heroku a Bokeh, встроенное в Flask

Мне удалось встроить граф сервера bokeh в Flask. Это выход на локальном хосте:Развертывание на сервере Heroku a Bokeh, встроенное в Flask

Проблема я не в состоянии сделать эту работу на Heroku. Все, что мне отображается, это текст «Вот ваш отличный сайт».

Итак, приложение составлено из трех файлов.

Там же сценарий, содержащий график:

#bokeh_plot.py 
import pandas as pd 

from bokeh.layouts import row, widgetbox 
from bokeh.models import Select 
from bokeh.palettes import Spectral5 
from bokeh.plotting import curdoc, figure 
from bokeh.sampledata.autompg import autompg 

df = autompg.copy() 

SIZES = list(range(6, 22, 3)) 
COLORS = Spectral5 
ORIGINS = ['North America', 'Europe', 'Asia'] 

# data cleanup 
df.cyl = [str(x) for x in df.cyl] 
df.origin = [ORIGINS[x-1] for x in df.origin] 

df['year'] = [str(x) for x in df.yr] 
del df['yr'] 

df['mfr'] = [x.split()[0] for x in df.name] 
df.loc[df.mfr=='chevy', 'mfr'] = 'chevrolet' 
df.loc[df.mfr=='chevroelt', 'mfr'] = 'chevrolet' 
df.loc[df.mfr=='maxda', 'mfr'] = 'mazda' 
df.loc[df.mfr=='mercedes-benz', 'mfr'] = 'mercedes' 
df.loc[df.mfr=='toyouta', 'mfr'] = 'toyota' 
df.loc[df.mfr=='vokswagen', 'mfr'] = 'volkswagen' 
df.loc[df.mfr=='vw', 'mfr'] = 'volkswagen' 
del df['name'] 

columns = sorted(df.columns) 
discrete = [x for x in columns if df[x].dtype == object] 
continuous = [x for x in columns if x not in discrete] 
quantileable = [x for x in continuous if len(df[x].unique()) > 20] 


def create_figure(): 
    xs = df[x.value].values 
    ys = df[y.value].values 
    x_title = x.value.title() 
    y_title = y.value.title() 

    kw = dict() 
    if x.value in discrete: 
     kw['x_range'] = sorted(set(xs)) 
    if y.value in discrete: 
     kw['y_range'] = sorted(set(ys)) 
    kw['title'] = "%s vs %s" % (x_title, y_title) 

    p = figure(plot_height=600, plot_width=800, tools='pan,box_zoom,reset', **kw) 
    p.xaxis.axis_label = x_title 
    p.yaxis.axis_label = y_title 

    if x.value in discrete: 
     p.xaxis.major_label_orientation = pd.np.pi/4 

    sz = 9 
    if size.value != 'None': 
     groups = pd.qcut(df[size.value].values, len(SIZES)) 
     sz = [SIZES[xx] for xx in groups.codes] 

    c = "#31AADE" 
    if color.value != 'None': 
     groups = pd.qcut(df[color.value].values, len(COLORS)) 
     c = [COLORS[xx] for xx in groups.codes] 
    p.circle(x=xs, y=ys, color=c, size=sz, line_color="white", alpha=0.6, hover_color='white', hover_alpha=0.5) 

    return p 


def update(attr, old, new): 
    layout.children[1] = create_figure() 


x = Select(title='X-Axis', value='mpg', options=columns) 
x.on_change('value', update) 

y = Select(title='Y-Axis', value='hp', options=columns) 
y.on_change('value', update) 

size = Select(title='Size', value='None', options=['None'] + quantileable) 
size.on_change('value', update) 

color = Select(title='Color', value='None', options=['None'] + quantileable) 
color.on_change('value', update) 

controls = widgetbox([x, y, color, size], width=200) 
layout = row(controls, create_figure()) 

curdoc().add_root(layout) 
curdoc().title = "Crossfilter"

Сценарий Настой:

#app.py

from bokeh.embed import autoload_server

app = Flask(__name__) 

bokeh_process = subprocess.Popen(

    return render_template("index.html", bokeh_script=bokeh_script) 

if __name__ == "__main__": 
    print("STARTED") 
    app.run(debug=True)

И шаблон index.html:

     <meta charset="utf-8">

    <body> 
     <p> This is your great site<p> 
     <div class="bk-root"> 
     {{ bokeh_script|safe }} 
     </div>

</html>

И это то, что я получаю от журналы героику. Заметьте, что есть линия Cannot start Bokeh server, port 5006 is already in use".

Я отчаянно искал ответ в Интернете, но ничего о том, как развернуть приложение опоки, которая содержит приложение сервера бока внутри не найден. Таким образом, этот пост может быть хорошим ресурсом, если кто-то может дать ответ.

Я считаю, что ключ находится в строке подпроцесса в файле app.py, где вызывается сервер bokeh, но мои знания в веб-службах ограничены, поэтому не могу понять, как заставить его работать. Есть идеи?

Редактировать 1: bigreddot предложил изменить значение -allow-websocket-origin на URL-адрес приложения. Итак, я изменил localhost: 5000 на bokehapp.herokuapp.com. Это похоже на исправление IOError: не удается поместить документ сессии. Однако график пока не отображается. Вот новые журналы, которые я получаю от Heroku:

Ну, одна проблема заключается в том, что 'allow-websocket-origin' сообщает серверу Bokeh, что нормально инициировать соединения с веб-сайтами, которые происходят из« где-то еще »(например, кто-то попадает на сервер Bokeh через встроенную веб-страницу, а не переходит непосредственно к Сервер Bokeh). Никто не будет * когда-либо * происходить из 'localhost', так что значение не может быть правильным. Это должно быть общедоступное ip/hostname, с помощью которого пользователи смогут перейти на страницу вашего флеш-приложения. – bigreddot

Возможны другие проблемы, их трудно диагностировать, не видя также журналы сервера Bokeh. – bigreddot

@bigreddot благодарит так много. Я изменил 'localhost: 5000' на' bokehapp.herokuapp.com', который является URL-адресом для приложения. Это избавилось от 'IOError: Can not pull session document'. Он также избавился от внутренней ошибки сервера, которую я получал, я посетил bokehapp.herokuapp.com. Тем не менее, график по-прежнему не отображается на веб-странице. Я не уверен, где можно увидеть журналы сервера Bokeh. Мне известно только о команде журнала heroku.Я отредактировал вопрос, чтобы показать последние журналы после предложенных изменений. Было бы здорово, если бы вы показали мне, как это еще больше диагностировать. – multigoodverse

Пожалуйста, проверьте эту ссылку http://blog.thedataincubator.com/2015/09/painlessly-deploying-data-apps-with-bokeh-flask-and-heroku/ Автор предложил использовать компонент компонентов Bokeh для генерации скрипта, который будет встроен в шаблон .html. Не уверен, что все еще нужны два веб-работника, хотя, поскольку я пытаюсь настроить приложение на Heroku.
