Enum FrozenNf4Error 

pub enum FrozenNf4Error<E>
where
    E: Debug,
{
    Native(E),
    TrainableBase,
    InputGradientNotDifferentiable,
}

Native failure or an unsupported derivative of the explicitly frozen NF4 base.

Variants

Native(E)

Original native backend error.

TrainableBase

Scales, codebook or bias must remain frozen, not learned QAT operands.

InputGradientNotDifferentiable

Original NF4 API provides first-order input gradients, not their derivatives.

Trait Implementations

impl<E> Debug for FrozenNf4Error<E>

where E: Debug,

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

Formats the value using the given formatter.

impl<E> Display for FrozenNf4Error<E>

where E: Debug,

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

Formats the value using the given formatter.

impl<E> Error for FrozenNf4Error<E>

where E: Debug,

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.
