`float8_e4m3_tensor`, `float8_e4m3_row`,  
- **Floating point X-bit quantization:**
- Full function names: `fpx_weight_only`
- Shorthands: `fpX_eAwB`, where `X` is the number of bits (between `1` to `7`), `A` is the number
of exponent bits and `B` is the number of mantissa bits. The constraint of `X == A + B + 1` must
be satisfied for a given shorthand notation.  
- **Unsigned Integer quantization:**
- Full function names: `uintx_weight_only`
