Errors produced by einsum, eval, and other tenferro operations.

Examples

use tenferro::error::Error;

let err = Error::InvalidSubscripts("rank mismatch".into());

Variants

InvalidSubscripts(String)

Einsum subscript string is invalid or cannot be parsed.

ContractionError(String)

Contraction optimization failed (shape mismatch, bad path, etc.).

MissingInput(String)

A required input tensor is missing from the inputs map.

NonScalarGrad

Reverse-mode gradient requires a scalar output.

Fields

shape: Vec<usize>

TensorRuntime(Error)

Runtime tensor execution failed in the backend layer.

UnexpectedBinding

A TracedTensor passed to eval_with_inputs bindings is not a placeholder (has attached data).

Fields

binding_index: usize

UnboundPlaceholder

A placeholder appearing in the graph has no binding supplied.

Fields

input_key: String

DuplicateBinding

The same placeholder was bound more than once in the bindings slice.

Fields

input_key: String

PlaceholderDtypeMismatch

A binding tensor’s dtype does not match the placeholder’s dtype.

Fields

expected: DType

actual: DType

PlaceholderShapeMismatch

A binding tensor’s shape does not match an input_concrete_shape placeholder’s fixed shape.

Fields

expected: Vec<usize>

actual: Vec<usize>

PlaceholderRankMismatch

A binding tensor’s rank does not match an input_symbolic_shape placeholder’s declared rank.

Fields

expected: usize

actual: usize

Internal(String)

An unexpected internal error.

Trait Implementations

impl Debug for Error

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

Formats the value using the given formatter.

impl Display for Error

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

Formats the value using the given formatter.

impl Error for Error

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<Error> for Error

fn from(source: Error) -> Self

Converts to this type from the input type.
