Plotly/Dash : AttributeError: module 'dash_bootstrap_components.themes' has no attribute 'ZEPHYR'

Dash Python

I am trying to design a dash app and am trying to use dash_bootstrap_components themes. I am able to use some themes like LUMEN but when I want to use the theme ZEPHYR I am getting the following error -

AttributeError: module 'dash_bootstrap_components.themes' has no attribute 'ZEPHYR'

This is the relevant code -

import pandas as pd
import numpy as np
from dash import dcc
from dash import html
from jupyter_dash import JupyterDash
from dash.dependencies import Output, Input, State
import dash_bootstrap_components as dbc
import dash
from dash.dependencies import Input, Output, State
from dash import dcc, html, dash_table

font_awesome_url = 'https://cdnjs.cloudflare.com/ajax/libs/font-awesome/4.7.0/css/font-awesome.min.css'

app = JupyterDash(__name__, 
                    external_stylesheets=[dbc.themes.ZEPHYR,font_awesome_url],
                    #meta_tags=[{'name': 'viewport','content': 'width=device-width, initial-scale=1.0'}],
                    prevent_initial_callbacks=True,
                    suppress_callback_exceptions=True
                    #assets_folder=assets_path
                )

Why is this happening?

Hi @Nil_97 Try upgrading to the lastest version of dash-bootstrap-components library. The Zephry theme was added as of V1.x

Thanks for your reply. I have upgraded dash_bootstrap_components to 1.2.0 but after upgrading I am getting the following warning -

Also when I am checking the version of dash_bootstrap_components in Jupyter notebook it is showing 0.13.1. Can you please help me resolve this?
