Hi,
With weasyprint (version 50), I'm getting a casting error when trying to convert a page -

  File "/usr/local/lib/python3.5/dist-packages/weasyprint/layout/flex.py", line 797, in flex_layout
    line.cross_size for line in flex_lines)
TypeError: unsupported operand type(s) for -: 'str' and 'float'

Unfortunately the page isn't public at the moment, so i can't share the page itself.

Hello,

Could you try the current master branch? An issue like this one has already been fixed since version 50 (#800).

Unfortunately I can't test this, as I'm working in an environment where I can install packages from pypi, but not those that require git.

You can launch pip install https://github.com/Kozea/WeasyPrint/archive/master.zip 😉.

Thanks, they somehow haven't blocked this yet.

The bug does seem to be fixed.

😢

Could you please provide an HTML sample that triggers this issue?

This has made me find the issue though - inline SVGs (which I know don't work anyway).

I'll convert my SVGs to data urls (or de-inline them) and everything should be fixed.

Apologies for the noise !
