Snakeviz not showing visualization via online jupyterLab

[kkruups]

Using myBinder to open an online instance of JupyterLab which is serving a notebook from a GitHub repository does not show the visualization although it generates the output rendered message stating it is embedding the Tmpfile to output cell.

The same behavior is observed via Google’s Colab Notebook online app.

How can this issue be resolved?

What additional info do you need?

I've never tried snakeviz in those environments, but I'd honestly be surprised if it works. The snakeviz magic requires starting a snakeviz web server via a subprocess and reading the page contents that way, and I bet Binder and Colab have security controls in place to prevent that kind of thing. 😞

OIC, so no workarounds that you can recommend?

No workarounds that I know of for using snakeviz itself in these environments, but I think you can still use the IPython %prun magic. It has the same underlying data as snakeviz without the interactive visualization.
