I'm just trying to get the Dash tutorial up and running but every time I try to run it, copy and pasted from the documentation into my asdf.py I get the error "ImportError: cannot import name 'dcc' from 'dash'". I've tried uninstalling and reinstalling dash, along with renaming the file and got nowhere. Any help is appreciated, thanks!
from dash import Dash, dcc, html, Input, Output
app = Dash(__name__)
app.layout = html.Div([
html.H6("Change the value in the text box to see callbacks in action!"),
html.Div([
"Input: ",
dcc.Input(id='my-input', value='initial value', type='text')
]),
html.Br(),
html.Div(id='my-output'),
])

Seems like this is the only thread for this specific problem. I ran the same code on Jupyter Notebooks only and never got an error. However when I opened the same notebook in VSCode it gave me the error. It also gave me an error for Flask. I resolved the error by downgrading my Python version to Python 3.9 - and magically I had no more import errors. My codeblock below for my imports. Uncomment the from dash-depencies and test:
import pandas as pd
import plotly.express as px # (version 4.7.0 or higher)
import plotly.graph_objects as go
import dash_core_components as dcc
#from dash.dependencies import Input, Output
from dash import Dash, dcc, html, Input, Output

Either try:
pip install dash --upgrade
or instead (for older versions):
import dash_core_components as dcc
import dash_html_components as html
from dash.dependencies import Input, Output
Hope this helps
