I'm unsure of how to establish a link between the python code and the browser. I see the presenter is using 127.0.0.8050. Is this universal?
I ran this code, but, I"m unsure of how to get this to appear in my chrome brower:
import pandas as pd
import plotly.express as px # (version 4.7.0)
import plotly.graph_objects as go
import dash # (version 1.12.0) pip install dash
import dash_core_components as dcc
import dash_html_components as html
from dash.dependencies import Input, Output
app = dash.Dash(__name__)
app,layout = html.div('Dash Tutorial')
if _name_ == '__main__':
app.run_server(debug=True)
how popular is dash nowadays?

Hello! great tutorial, would we be able to find your code that you used to do this type of example for your Vehicle Data? I also have sensor data live updating and would like to plot it with Dash! Cheers

i want to create a same kind of dashboard with python and SQL SERVER database can you pls suggest me some links .. thank you 🙂
Justpy and Streamlit are also gradually growing and getting popular in building interactive web apps in python
Do you recommend learning Plotly before learning about Dash? Aside from python basics, what are the prerequisites for learning Dash?
Coding starts near 3:54
AttributeError: 'Div' object has no attribute 'run_server'
Somebody had this problem?
I can't fix it.
Thanx a lot

anything I search related to python, dex, you pop up every time… hats off man… you're doing a great job
Great tutorial, Can dash work with real time data input from a python file?
You are one of the decent programmers i ever learned from , please keep up with more dashboards in Machine learning as it is the trend right now specially corona dashboards, i want to learn more from you
127.0.0.1:8050 is not opening what to do can anyone help ??
nice tutorial, thanks for the introduction to this nice package! =)
in linux, to kill the server, just hit Ctrl+C. also, please don't do `sudo pip install`, you can mess up system's python. use environments instead.
For windows users who are using jupyter notebook/Spyder and facing 'system error: 1', you can try setting debug=False in
if _name_ == '__main__':
app.run_server(debug=False)

Love you man!
My brain hurts
Bro, I just want to say THANK YOU. THANK YOU SO MUCH. Because you're the best man honestly. I think I've learned absolutely everything I know coding-wise thanks to you and only you. Love your tutorials. Once again, thank you!
can i pass actual data frame values
i find it much easier using dict() than {}
How come you're saying "Our Channel" now Sentdex? Have you got an employee now?
how can i make a live graph of signals which sent to raspberryi pi? i mean there is an application and when you select an option(stimulaiton) from this, this sends a stimulation to rat.and for example you can choose waiting time, stimulation, frequnency. i want to display this 0-1 signals. (each stimulation is 1, during delay time is 0)
I tried but got name error , name not found
I just stumbled onto dash today while looking up ways to make a dashboard with python and was excited about it because I think I'll be able to do what I want to do with this, but even more exciting was to find that Sentdex already had a tutorial ready about this subject! 🙏
Hey Harrison,
@sentdex
I'm getting the following error:
Running on http://127.0.0.1:8050/
Debugger PIN: 259-348-800
* Serving Flask app "__main__" (lazy loading)
* Environment: production

An exception has occurred, use %tb to see the full traceback.
So, What to do to over come this?
I have installed "pip install dash dash-renderer dash-html-components dash-core-components plotly" package based on "https://stackoverflow.com/questions/54912449/problems-running-dash-in-jupyter-notebook" link. But still its not working.
I'm looking forward to your reply.
I"m getting the below error. Do I need to install anything or give admin privilages ?

hi Guys, how can i add multiple y-axis in this plot like one yaxis on left and another on right side. Thanks
How to embed to Flask app? any video?
ctrl c kills my servers but im in linux. You could also write a shell script in your directory to kill running processes on a certain port
OH GAWD! THAT IS JUST HORRIBLE!!!!
hey @sentdex i think i did everything write from your tutorial… but some how the dash tutorial message is not showing on my browser i saw some error msgs on my screen their is a list of them the first one is line 10, in <module>
app.run_server(debug=True) not sure what this means this means
Note: starting with dash 0.37.0, dash automatically installs dash-renderer, dash-core-components, dash-html-components, and dash-table, using known-compatible versions of each. You need not and should not install these separately any longer, only dash itself.
