Why My pyecharts Chart Won’t Render in Jupyter and How to Fix It

1. Introduction

A Python enthusiast asked in a community why a pyecharts chart could not be displayed in Jupyter, mentioning that online resources were supposed to be installed locally but an error occurred.

2. Troubleshooting Process

Community members suggested several approaches: adding an exclamation mark before the git command, ensuring git is installed, downloading the required pyecharts resource package, opening the generated HTML file directly, and renaming any Chinese characters in the file path to English.

One user recommended setting the online host to a CDN so that the assets are loaded from the internet.

from pyecharts.globals import CurrentConfig

CurrentConfig.ONLINE_HOST = "https://cdn.kesci.com/lib/pyecharts_assets/"

After applying the configuration, the chart still did not render in Jupyter, but the generated HTML file could be opened in a browser, confirming that the issue was specific to Jupyter’s rendering method.

3. Conclusion

The problem was resolved by configuring pyecharts to load assets from an online CDN and by understanding the difference between Jupyter rendering and static HTML rendering.
