Ciao Josh,
Thanks for looking into this. Indeed I was checking without lhapdf, so it
makes sense.
I will be with bad connection this week, as I will be in the mountains.
When I will be back I will try to fix the bug ASAP.
In the meantime, note that nnpdf 2.3 is available also without lhapdf.
Cheers,

Marco
