Methods
from_dtype
static from_dtype[dtype: DType]() -> Self
Converts a Mojo DType to the corresponding TMA data type.
Constraints:
The dtype must be float32, bfloat16, or float8_e4m3fn.
Parameters:
- dtype (
DType): The Mojo data type to convert. Must be one ofDType.float32,DType.bfloat16, orDType.float8_e4m3fn.
Returns:
Self: The corresponding TensorMapDataType value.
