}

Errors that can arise during DNN operations.

Variants

Cuda(CudaError)

A low-level CUDA driver call failed.

Blas(BlasError)

A BLAS operation failed (e.g. during convolution via im2col + GEMM).

PtxGeneration(String)

PTX kernel generation or compilation failed.

InvalidDimension(String)

Tensor dimensions are invalid (e.g. zero-sized, negative, or inconsistent with the expected layout).

BufferTooSmall

The supplied device buffer is too small for the described tensor.

Fields

expected: usize

Minimum required buffer size in bytes.

actual: usize

Actual buffer size in bytes.

UnsupportedOperation(String)

The requested operation is not supported for the given configuration (e.g. unsupported data type or algorithm on a particular SM version).

InvalidArgument(String)

A function argument failed validation.

WorkspaceRequired(usize)

The operation requires a workspace buffer of at least the given size, but none (or too small) was provided.

LaunchFailed(String)

A GPU kernel launch failed.

Io(Error)

An I/O error occurred (e.g. when reading/writing the PTX cache).

Trait Implementations

impl Debug for DnnError

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

Formats the value using the given formatter.

impl Display for DnnError

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

Formats the value using the given formatter.

impl Error for DnnError

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.
