nanohub-gradio Documentation

nanohub-gradio is a Python package for running Gradio applications on the nanoHUB platform. It provides tools to configure the environment variables and proxy settings needed to deploy Gradio apps behind the nanoHUB weber proxy.

Features

  • Jupyter Magic Command (%set_dash_env): Configure environment variables for Dash apps directly in Jupyter notebooks

  • Command-line Tool (start_dash): Launch Dash applications with automatic proxy configuration and header injection

Quick Start

Install the package:

pip install nanohub-gradio

In a Jupyter notebook on nanoHUB:

%load_ext nanohubdash
%set_dash_env

import os
from dash import Dash, html

app = Dash(__name__,
    routes_pathname_prefix=os.getenv("DASH_ROUTES_PATHNAME_PREFIX"),
    requests_pathname_prefix=os.getenv("DASH_REQUESTS_PATHNAME_PREFIX")
)
app.layout = html.Div("Hello nanoHUB!")

if __name__ == "__main__":
    app.run(
        jupyter_server_url=os.environ.get("DASH_BASE_PROXY"),
        host=os.environ.get("DASH_HOST", "0.0.0.0"),
        port=os.environ.get("DASH_PORT", "8001"),
    )
