This is not the final solution, but using a backend absolute path and passing that to the frontend cannot work in the general case.

Thanks @davidbrochart !

Well, CI is passing and testing the Python API from the notebook. Let's merge?

Hmm I think the examples/Notebook.ipynb doesn't work with this change?

[martinRenou]

We're supposed to have visual regression tests running this notebook, I'm not sure why it doesn't complain

[davidbrochart]

Maybe Jupyter is launched inside examples in the CI?

Closing as it's already included as part of #412
