Problems running Dash in Jupyter notebook
Solution 1
This is the tutorial you are looking for https://plot.ly/python/ipython-notebook-tutorial/. As Alexander explained Dash is a web server. If you are just learning python and want to plot stuff with Jupyter, running a webserver is not what you need. Instead you have to install a plot library like plotly
or my favorite matplotlib
. To install it, you would run ! pip install plotly
from inside Jupyter. The tutorial will walk you through it.
Solution 2
Your last picture shows that dash is working perfectly fine Go to the URL that is indicated in the terminal

I just copy and paste the first batch of code from : https://dash.plot.ly/getting-started to my Jupyter notebook and this what I am getting:
Running on http://127.0.0.1:8050/ Debugger PIN: 124-434-522 Debugger PIN: 124-434-522 Debugger PIN: 124-434-522 Debugger PIN: 124-434-522 * Serving Flask app "__main__" (lazy loading) * Environment: production WARNING: Do not use the development server in a production environment. Use a production WSGI server instead. * Debug mode: on An exception has occurred, use %tb to see the full traceback. SystemExit: 1
Any help will be more than appreciated.
(Updated comment) I have aslo tried google colab. Unfortunately it doesn't work on it neither. this is what I am getting:
# -*- coding: utf-8 -*- import dash import dash_core_components as dcc import dash_html_components as html external_stylesheets = ['https://codepen.io/chriddyp/pen/bWLwgP.css'] app = dash.Dash(__name__, external_stylesheets=external_stylesheets) app.layout = html.Div(children=[ html.H1(children='Hello Dash'), html.Div(children=''' Dash: A web application framework for Python. '''), dcc.Graph( id='example-graph', figure={ 'data': [ {'x': [1, 2, 3], 'y': [4, 1, 2], 'type': 'bar', 'name': 'SF'}, {'x': [1, 2, 3], 'y': [2, 4, 5], 'type': 'bar', 'name': u'Montréal'}, ], 'layout': { 'title': 'Dash Data Visualization' } } ) ]) if __name__ == '__main__': app.run_server(debug=True)

(Second update) I am running the same script in Atom. Unfortunately it doesn't seen to be working:
I don't understand what I am doing wrong.
