I’m trying to use this library: Dash Bootstrap Theme Explorer
it styles Plotly Dash apps with a Bootstrap theme but when I try to import it is apparently not recognized
I couldn’t identify the problem…
import dash
from dash import html, dcc
from dash.dependencies import Input, Output
from matplotlib.pyplot import margins
import pandas as pd
import numpy as np
import dash_bootstrap_components as dbc
from app import *
from dash_bootstrap_templates import load_figure_template
import plotly.express as px
import plotly.graph_objects as go
load_figure_template(PULSE)
app = dash.Dash(__name__, external_stylesheets=[dbc.themes.PULSE])
server = app.server
Import “dash_bootstrap_templates” could not be resolved
Hi @Luisanches
The issue might be in this line:
load_figure_template(PULSE)
Try changing it to:
load_figure_template("pulse")
What version of dash-bootstrap-templates do you have installed?
Can you try running this minimal example?
import dash_bootstrap_components as dbc
from dash_bootstrap_templates import load_figure_template
import plotly.express as px
df = px.data.gapminder()
# Makes the Bootstrap Themed Plotly templates available
load_figure_template("pulse")
fig = px.scatter(
df.query("year==2007"),
x="gdpPercap",
y="lifeExp",
size="pop",
color="continent",
log_x=True,
size_max=60,
template="pulse", # use the pulse themed figure template
title="Gapminder 2007: Pulse Theme",
)
app = Dash(__name__, external_stylesheets=[dbc.themes.PULSE])
app.layout = dbc.Container(dcc.Graph(figure=fig, className="m-4"))
if __name__ == "__main__":
app.run_server(debug=True)

Hi @AnnMarieW, I did what you told me, and I even reinstalled the library, the import now worked after reinstalling but another error occurred:
from dash import html, dcc, Input, Output, State, callback, clientside_callback, MATCH
ImportError: cannot import name 'Input' from 'dash'
I think there is some conflict between the libraries but I don’t know what to do…
version of dash-bootstrap-templates installed: dash-bootstrap-templates==1.0.7
from dash import html, dcc, Input, Output, State, callback, clientside_callback, MATCH
ImportError: cannot import name 'Input' from 'dash'
It looks like something changed from your old routing in your original post you had Input, Output[, State] importing from dash.dependencies.
What version of dash are you running?

This is the version: dash 2.6.2
Hi @Luisanches
You see this error if you run dash < 2.0.0:
ImportError: cannot import name 'Input' from 'dash'
It may be that the app is not actually using the current version of dash. At the beginning of your app, try adding:
import dash
print(dash.__version__)

in fact it returned me this: 1.0.0
So what to do in this case of dash not running in the correct version?
If this is inside an environment, navigate to the virtual environment and you should be able to:
pip install -U dash

I did this and it returned this:
Requirement already satisfied, skipping upgrade: typing-extensions>=3.6.4; python_version < "3.8" in /home/sanches/anaconda3/lib/python3.7/site-packages (from importlib-metadata>=3.6.0; python_version < "3.10"->Flask>=1.0.4->dash) (4.3.0)
but when I run the code it didn’t work, still with the same error…
from dash import html, dcc, Input, Output, State, callback, clientside_callback, MATCH
ImportError: cannot import name 'Input' from 'dash'
Did you get an error along the lines of something about pip?
This is the complete error I get:

I fixed the problem.
I had to uninstall the 3 dash libraries I was using:
pip uninstall dash
pip uninstall dash-bootstrap-templates
pip uninstall dash-bootstrap-templates
and then install again and update:
pip install dash --upgrade
pip install dash-bootstrap-templates --upgrade
pip install dash-bootstrap-templates
pip3 install --upgrade requests
