I guess you can always just add an assert not data.isna().any() in strategic locations

That could be a nice way. Sadly it was in a C++ code base (using tensorflow). Therefore no such nice things (would be slow too). I skill-issued myself thinking a struct would be 0 -initialized but MyStruct input; would not while MyStruct input {}; will (that was the fix). Long story.

I too have forgotten to memset my structs in c++ tensorflow after prototyping in python.

If you use the GNU libc the feenableexcept function, which you can use to enable certain floating point exceptions, could be useful to catch unexpected/unwanted NaNs

Oof. This makes me appreciate the abstractions in Go. It's a small thing but initializing structs with zero values by default is nice.

Oof. C++ really is a harsh mistress.
