CheckNumerics
Tetap teratur dengan koleksi
Simpan dan kategorikan konten berdasarkan preferensi Anda.
Memeriksa tensor untuk nilai NaN, -Inf, dan +Inf.
Saat dijalankan, laporkan kesalahan `InvalidArgument` jika `tensor` memiliki nilai apa pun yang bukan angka (NaN) atau tak terhingga (Inf). Jika tidak, lewati `tensor` apa adanya. Tidak seperti CheckNumerics (V1), CheckNumericsV2 membedakan -Inf dan +Inf dalam kesalahan yang ditimbulkannya.
