Errors that can occur while inferring an Ultralytics schema.

Variants

NotUltralytics(String)

Model metadata carries no Ultralytics signature.

BadNames(String)

The Ultralytics names metadata field could not be parsed.

BadMetadata(String)

A metadata field is present but carries a value that cannot be interpreted. Distinct from an absent field, which is allowed to select a fallback.

UnsupportedTask(String)

The Ultralytics task metadata field names an unsupported task.

ClassCountMismatch

The number of classes in names does not match what the output tensor shapes imply.

Fields

expected: usize

found: usize

UnsupportedLayout(String)

The output tensor layout does not match any supported Ultralytics convention.

AmbiguousLayout(String)

More than one output matches the same layout, so which tensor carries the detections depends on the order the runtime reported them. Reported rather than resolved by position.

UnsupportedQuantization(String)

A boundary tensor carries quantization the decoder cannot consume. Currently this means per-channel quantization: the decoder supports per-tensor only, so such a schema would build a decoder that fails.

UnknownBoxConvention

The signals came from ModelSource::Other, for which the box coordinate convention is unmeasured. Only the ONNX (pixel-space) and TFLite ([0, 1]) conventions are characterized, and picking the wrong one silently scales every box by the input size.

Trait Implementations

impl Debug for InferError

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

Formats the value using the given formatter.

impl Display for InferError

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

Formats the value using the given formatter.

impl Error for InferError

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>)
