Enum GradientTransformError 

pub enum GradientTransformError {
    InvalidScalar,
    InvalidDType,
    ParameterMismatch(ParamId),
    QuantizedGradient(ParamId),
    UnknownParameters,
}

Invalid gradient metadata or an explicit scaling argument.

Variants

InvalidScalar

The multiplier/divisor is not finite or cannot be represented in the work dtype.

InvalidDType

The requested arithmetic dtype is not F32 or F64.

ParameterMismatch(ParamId)

A gradient does not have its parameter’s geometry or device.

QuantizedGradient(ParamId)

A gradient is quantized; arithmetic must not silently dequantize it.

UnknownParameters

At least one registered gradient is not owned by the supplied module.

Trait Implementations

impl Clone for GradientTransformError

fn clone(&self) -> Self

Returns a duplicate of the value.

fn clone_from(&mut self, source: &Self)

Performs copy-assignment from source.

impl Debug for GradientTransformError

fn fmt(&self, f: &mut Formatter<'_>) -> Result

Formats the value using the given formatter.

impl Display for GradientTransformError

fn fmt(&self, f: &mut Formatter<'_>) -> Result

impl Eq for GradientTransformError

impl Error for GradientTransformError

Available on crate feature std only.

fn source(&self) -> Option<&(dyn Error + 'static)>

Returns the lower-level source of this error, if any.

fn description(&self) -> &str

👎Deprecated since 1.42.0:

use the Display impl or to_string()

fn cause(&self) -> Option<&dyn Error>

👎Deprecated since 1.33.0:

replaced by Error::source, which can support downcasting

fn provide<'a>(&'a self, request: &mut Request<'a>)

🔬This is a nightly-only experimental API. (error_generic_member_access)

Provides type-based access to context intended for error reports.

impl From<GradientTransformError> for WeightedAccumulationError

fn from(error: GradientTransformError) -> Self

Converts to this type from the input type.

impl PartialEq for GradientTransformError

fn eq(&self, other: &Self) -> bool

Equality operator ==.
