Bereitstellen auf Heroku ein Bokeh-Server-Plot eingebettet in Flask

Ich konnte ein Bokeh-Server-Diagramm in Flask einbetten. Dies ist die Ausgabe auf localhost:Bereitstellen auf Heroku ein Bokeh-Server-Plot eingebettet in Flask

Problem ist, ich bin in der Lage, diese Arbeit nicht auf Heroku zu machen. Alles, was ich angezeigt bekomme, ist der Text "Hier ist deine großartige Seite".

Also besteht die App aus drei Dateien.

Es gibt das Skript das Diagramm enthält:

#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

df = autompg.copy() 

SIZES = list(range(6, 22, 3))

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'

del df['name']

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)

    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)

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

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

die Flasche Skript:

#app.py 
import subprocess 
import atexit 
from flask import render_template, render_template_string, Flask 
from bokeh.embed import autoload_server 
from bokeh.client import pull_session 

app = Flask(__name__) 

bokeh_process = subprocess.Popen(
    ['bokeh', 'serve','--allow-websocket-origin=localhost:5000','bokeh_plot.py'], stdout=subprocess.PIPE) 

@atexit.register 
def kill_server(): 
    bokeh_process.kill() 

@app.route("/") 
def index(): 
    session=pull_session(app_path="/bokeh_plot") 
    bokeh_script=autoload_server(None,app_path="/bokeh_plot",session_id=session.id) 
    return render_template("index.html", bokeh_script=bokeh_script) 

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

Und die index.html Vorlage:

<!DOCTYPE html> 
<html lang="en"> 
    <head> 
     <style> 
      @import url(https://fonts.googleapis.com/css?family=Noto+Sans);

     <meta charset="utf-8">

     <div class="bk-root">

    </body> 
</html>

Und das ist, was ich von die Heroku-Protokolle. Beachten Sie, dass dort eine Cannot start Bokeh server, port 5006 is already in use" Linie ist.

Ich habe verzweifelt nach einer Antwort auf das Web durchsucht, haben aber nichts auf gefunden, wie eine Flasche App bereitstellen, die innerhalb eines Bokeh Server-Anwendung enthält. Also, dieser Beitrag könnte eine gute Ressource sein, wenn jemand in der Lage ist, eine Antwort zu geben.

Ich glaube, der Schlüssel ist in der Unterprozesslinie in der Datei app.py, wo der Bokeh-Server aufgerufen wird, aber mein Wissen in Web-Services ist begrenzt, kann nicht herausfinden, wie es funktioniert. Irgendeine Idee?

Bearbeiten 1: bigreddot vorgeschlagen, den Wert von --allow-websocket-Herkunft auf die URL der App zu ändern. Also änderte ich localhost: 5000 zu bokehapp.herokuapp.com. Das scheint den IOError zu beheben: Sitzungsdokument kann nicht eingefügt werden. Das Diagramm wird jedoch weiterhin nicht angezeigt. Hier sind die neuen Protokolle I von Heroku erhalten:

Nun ein Problem ist, dass 'allow-websocket-origin' dem Bokeh-Server mitteilt, dass es in Ordnung ist, Websocket-Verbindungen von" woanders "zu initiieren (zB wenn jemand den Bokeh-Server über eine eingebettete Webseite ansteuert) Bokeh Server). Niemand wird * jemals * von 'localhost' stammen, so dass der Wert nicht stimmen kann. Es sollte der öffentliche ip/hostname sein, mit dem Nutzer navigieren, um Ihre flask-App-Seite zu sehen. – bigreddot

Es kann andere Probleme geben, es ist schwer zu diagnostizieren, ohne auch die Protokolle des Bokeh-Servers zu sehen. – bigreddot

@bigreddot vielen Dank. Ich habe 'localhost: 5000' in' bokehapp.herokuapp.com' geändert, welches die URL für die App ist. Das löste den 'IOError: Session-Dokument kann nicht abgerufen werden'. Es wurde auch der interne Serverfehler beseitigt, den ich bekam, besuchte ich bokehapp.herokuapp.com. Das Diagramm wird jedoch immer noch nicht auf der Webseite angezeigt. Ich bin mir nicht sicher, wo ich die Bokeh-Server-Logs sehen kann. Mir ist nur der Befehl heroku logs bekannt.Ich habe die Frage bearbeitet, um die neuesten Protokolle nach den vorgeschlagenen Änderungen anzuzeigen. Wäre toll, wenn Sie mir zeigen würden, wie man das noch weiter diagnostiziert. – multigoodverse

Bitte überprüfen Sie diesen Link http://blog.thedataincubator.com/2015/09/painlessly-deploying-data-apps-with-bokeh-flask-and-heroku/ Der Autor schlug vor, die Bokeh-Komponentenmethode zu verwenden, um ein Skript zu generieren, das in die HTML-Vorlage eingebettet wird. Ich bin mir nicht sicher, ob es immer noch zwei Web-Arbeiter braucht, da ich versuche, meine App auch auf Heroku laufen zu lassen.

Während dieser Link die Frage beantworten kann, ist es besser, die wesentlichen Teile der Antwort hier aufzunehmen und den Link als Referenz zur Verfügung zu stellen. Nur-Link-Antworten können ungültig werden, wenn sich die verknüpfte Seite ändert. – mbomb007
