Log scalar data.

Parameters:

• name (str) – tag name used to group scalars

• data (Scalar) – scalar data to log

• step (int) – step value to record

log_dict(payload: Mapping[str, Union[Tensor, ndarray, int, float]], step: int) → None

Log multiple scalar values.

Parameters:

• payload (Mapping[str, Scalar]) – dictionary of tag name and scalar value
