This error should be caught and properly handled.

Variants

PlanesUnavailable

Indicate that the hardware / API doesn’t support SIMT plane instructions.

CubeCountTooLarge

When the cube count is bigger than the max supported.

Validation

A generic validation error

Fields

details: &'static str

ImprecisePlaneDim

Indicate that min_plane_dim != max_plane_dim, thus the exact plane_dim is not fixed.

InvalidAxis

Indicate the axis is too large.

Fields

axis: usize

rank: usize

ReduceAxisTooSmall

Indicate that the shape of the input tensor is too small for the given input and axis.

Fields

axis_length: usize

k: usize

MismatchOutputShape

Indicate that the shape of the output tensor is invalid for the given input and axis.

Fields

expected_shape: Vec<usize>

output_shape: Vec<usize>

MismatchIndicesShape

Indicate that the indices output shape does not match the values output shape.

Fields

values_shape: Vec<usize>

indices_shape: Vec<usize>

MismatchIndicesStrides

Indicate that the indices output strides do not match the values output strides.

Fields

values_strides: Vec<usize>

indices_strides: Vec<usize>

IndicesUnsupported

Indicate the operation cannot report indices alongside its values.

Fields

operation: &'static str

MissingAtomicAdd(ElemType)

Indicate that we can’t launch a shared sum because the atomic addition is not supported.

SharedMemoryOverflow

The selected blueprint stages more accumulators in shared memory than the device allows.

Fields

requested: usize

available: usize

Launch(LaunchError)

An error happened during launch.

Trait Implementations

impl Clone for ReduceError

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 ReduceError

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

Formats the value using the given formatter.

impl Display for ReduceError

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

Formats the value using the given formatter.

impl Error for ReduceError

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.
