Pruning operation errors with detailed context.

Toyota Way: Andon

Errors contain actionable information for diagnosis. Each variant provides specific context to help identify and resolve issues quickly.

Variants

NumericalInstability

Numerical instability detected (NaN/Inf in scores).

Jidoka Principle

Stop immediately when numerical issues are detected rather than propagating bad values downstream.

Fields

method: String

Method that detected the instability

details: String

Detailed description of what was detected

CalibrationRequired

Calibration data required but not provided.

Methods like Wanda require activation statistics from calibration data to compute importance scores.

Fields

method: String

Method requiring calibration

ShapeMismatch

Tensor shape mismatch.

Occurs when mask and weight tensor shapes don’t align.

Fields

expected: Vec<usize>

Expected shape

got: Vec<usize>

Actual shape found

InvalidMask

Invalid sparsity mask.

Masks must contain only binary values (0.0 or 1.0).

Fields

reason: String

Reason for invalidity

InvalidPattern

Invalid sparsity pattern configuration.

For N:M patterns, N must be less than M.

Fields

message: String

Error message describing the invalid configuration

MissingActivationStats

Missing activation statistics for a layer.

The calibration context doesn’t have stats for this layer.

Fields

layer: String

Layer name that’s missing stats

InvalidSparsity

Invalid sparsity target.

Sparsity must be in range [0.0, 1.0].

Fields

value: f32

Provided value

constraint: String

Constraint description

NoParameters

Module has no parameters to prune.

Fields

module: String

Module identifier or description

Trait Implementations

impl Clone for PruningError

fn clone(&self) -> PruningError

Returns a duplicate of the value.

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

Performs copy-assignment from source.

impl Debug for PruningError

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

Formats the value using the given formatter.

impl Display for PruningError

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

Formats the value using the given formatter.

impl Error for PruningError

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.
