Known Issues

Below is a list of known issues with brian2wasm. For additional details or to report new issues, visit the bug tracker on GitHub.

• Automatic Device Setting:

  When using the brian2wasm CLI tool, do not call set_device(...) in your Brian 2 script. The CLI automatically configures the device, and adding your own call may cause errors or unexpected behavior.

  However, if you are not using the CLI (e.g. running a script directly in Python), you can still manually set the device to wasm_standalone with set_device("wasm_standalone").

• Plotly CDN Dependency: The generated HTML files rely on Plotly charts that load assets from a CDN (https://cdn.plot.ly/plotly-latest.min.js). An internet connection is required for these charts to render properly.

Warning

If the CDN is inaccessible (e.g., due to network issues or restrictions), Plotly charts will not load. Consider hosting Plotly locally for offline use.
