Took me 2 hours to find out why the final output of a neural network was a bunch of NaN. This is always very annoying but I can't really complain, it make sense. Just sucks.
I hope it was garlic NaN at least.
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. C++ really is a harsh mistress.
Oof. This makes me appreciate the abstractions in Go. It's a small thing but initializing structs with zero values by default is nice.
this is just like in regular math too. not being a number is just so fun that nobody wants to go back to being a number once they get a taste of it
Thanks. This is great
Fucking over-dramatic divisions by 0, sigh.
Also applies to nulls in SQL queries.
It's not fun tracing where nulls are coming from when dealing with a 1500 line data warehouse pipeline query that aggregates 20 different tables.
"Bounds checking, mobof--ker! Do you speak it?"
Consider IEEE754 arithmetic as monadic, simple!
As I was coding in C++ my own Engine with OpenGL. I forgot something to do. Maybe forgot to assign a pointer or forgot to pass a variable. At the end I had copied a NaN value to a vertieces of my Model as the Model should be a wrapper for Data I wanted to read and visualize.
Printing the entire Model into the terminal confused me why everything is NaN suddenly when it started nicely.
NaN is such a fun floating point virus. Some really wonky gameplay after we hit NaN in a few spots.
Nanananana! Batman!
This gave me some real Agent Smith vibes
