AttributeError: partially initialized module 'dash_html_components' has no attribute 'Div' (most likely due to a circular import)

[pantinashekhar]

import dash_html_components as html 
app = Dash(__name__)
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(host='127.0.0.1',port='8050',debug=True)

Dash app is not working because of layout not being there but when I included then the error as shown in title comes.Please request you to help me at the earliest.

This sounds similar to #1143 (which has been fixed in the dev branch but not yet released). What is the name of this file?

yep, that would be it - you can't give your own script a name that matches any of the packages in your system, or when someone else (in this case dash_html_components) tries to do import dash they'll get your file rather than the installed package. Just change the name to something unique.

Ok I will look into it.Thanks for the prompt reply.

After changing dash to dashed the errors have reduced.but the error I m getting is class Dash(object) which we defined when I wrote app = Dash() it says Dash is not defined. On Wed, 16 Dec 2020, 19:41 pantina chandrashekhar, < [email protected]> wrote:

haha I wondered about that - you need from dash import Dash

Wow, line 1760... you have a lot of code in this file. I'd guess unmatched parentheses or something like that somewhere above this line, but I'd recommend getting an IDE with Python syntax checking, that should help you find the problem. The short code you posted first works fine for me once I add the two additional import statements (dash and dcc)

Ok thanks I will look into it.

Closing, as this issue won't lead to code changes in this repo. For further usage questions, a better forum may be https://community.plotly.com/c/dash/16

Thanks!
