1.9.1 verified Fri May 01 auth: no python maintenance

pip install dash-renderer

Common errors

error ModuleNotFoundError: No module named 'dash_renderer' ↓

cause Trying to import dash_renderer before installing dash or dash-renderer.

fix

Install dash (which includes dash-renderer) with 'pip install dash'.

error ImportError: cannot import name 'renderer' from 'dash_renderer' ↓

cause Wrong import path; dash_renderer is a module, not a package with a renderer class.

fix

Do not import anything from dash_renderer; it's used internally by Dash.

error dash-renderer has no attribute 'frontend' ↓

cause Attempting to access the renderer directly.

fix

Access the renderer through the Dash app object if needed (e.g., app.renderer).

Warnings

deprecated dash-renderer is deprecated in favor of Dash's built-in renderer. Version 1.9.1 is the final release. ↓

fix Do not install dash-renderer separately; use Dash (>=2.0.0) which includes its own renderer.

gotcha Importing dash_renderer directly is unnecessary and may cause confusion. It's automatically loaded when you import dash. ↓

fix Simply import dash; do not add any dash-renderer import.

breaking dash-renderer v1.9.1 is not compatible with Python 2.7 or older versions of React. ↓

fix Use Python 3.5+ and ensure you are using a compatible version of Dash.

Imports

dash_renderer
wrong
```
from dash_renderer import renderer
```
correct
```
import dash_renderer
```
dash-renderer is imported as a module, not a class; it's auto-registered when dash is imported.

Quickstart

Dash apps automatically use dash-renderer for front-end rendering; no direct import required.

import dash
import dash_core_components as dcc
import dash_html_components as html

app = dash.Dash(__name__)

app.layout = html.Div([
    dcc.Input(id='input', type='text'),
    html.Div(id='output')
])

if __name__ == '__main__':
    app.run(debug=True)
