ImportError: cannot import name 'get_current_traceback' from 'werkzeug.debug.tbtools'

Dash Python
1

Hi,

I’m new to Dash and am learning from the tutorial. After installation, I tried to run the first example (see below), but immediately ran into issue importing dash. This is the error message:
ImportError: cannot import name ‘get_current_traceback’ from 'werkzeug.debug.tbtools’

Any idea? Thanks!

Here is the code

Run this app with python app.py and

visit http://127.0.0.1:8050/ in your web browser.

from dash import Dash, html, dcc
import plotly.express as px
import pandas as pd

app = Dash(name)

assume you have a “long-form” data frame

see Plotly express arguments with Python for more options

df = pd.DataFrame({
“Fruit”: [“Apples”, “Oranges”, “Bananas”, “Apples”, “Oranges”, “Bananas”],
“Amount”: [4, 1, 2, 2, 4, 5],
“City”: [“SF”, “SF”, “SF”, “Montreal”, “Montreal”, “Montreal”]
})

fig = px.bar(df, x=“Fruit”, y=“Amount”, color=“City”, barmode=“group”)

app.layout = html.Div(children=[
html.H1(children=‘Hello Dash’),

html.Div(children='''
    Dash: A web application framework for your data.
'''),

dcc.Graph(
    id='example-graph',
    figure=fig
)

])

if name == ‘main’:
app.run_server(debug=True)
