AttributeError: module 'dash' has no attribute 'Dash'

Im a beginner, till yesterday i was running a code, wich was running fine, but today when i ran the same code, it started giving me this error below:

“Traceback (most recent call last):

I searched over internet to interpret this but i couldn’t… Tried with the code as basic as

import dash
import dash_core_components as dcc
import dash_html_components as html

app = dash.Dash()
app.layout = html.Div([


Still even this is not working. Can anyone help ?

do you happen to have a file named dash.py? The JupyterDash code might be importing that file instead of importing the dash module.

No, i don’t have any file with that name, i just now activated my conda base and opened a new jupyter notebook to run my .py file.

IT WORKED !! , still couldn’t understand exactly what had happened.

Interesting. I just ran into the same problem with a file called test.py in that directory.

Can confirm having a test.py file in the cwd will cause this error.


Same trouble using a test.py file. Just change name and it works :thinking:

test.py is the problem, change it. it will be work right away.

If there is a test.py file in your directory, this error will happen if you try to run this file or any other file in that directory.
