Expand description

Errors encountered during the loading process.

Variants§

§

OpenFileFailed

A file failed to open.

Fields

§source: Error

The original error.

§path: PathBuf

The path that failed.

§

NoParentPath

There is no parent path for a given path.

Fields

§path: PathBuf

The path without a parent.

§

ReadExactFailed

Reading exactly bytes from a file failed.

Fields

§source: Error

The original error.

§bytes: usize

The number of bytes that were attempted to be read.

§

Io(Error)

A non-specific IO error.

§

InvalidUtf8(FromUtf8Error)

One of the strings encountered was not valid UTF-8.

§

InvalidIntegerConversion(TryFromIntError)

One of the integers encountered could not be converted to a more appropriate type.

§

UnsupportedFileType(i32)

The f16_ hyperparameter had an invalid value.

§

InvalidMagic

An invalid magic number was encountered during the loading process.

Fields

§path: PathBuf

The path that failed.

§magic: u32

The magic number that was encountered.

§

InvalidFormatVersion

The version of the format is not supported by this version of llm.

Fields

§container_type: ContainerType

The format that was encountered.

§version: u32

The version that was encountered.

§

HyperparametersF16Invalid

The f16 hyperparameter had an invalid value.

Fields

§ftype: i32

The format type that was encountered.

§

UnknownTensor

The tensor tensor_name was encountered during the loading of path, but was not seen during the model prelude.

Fields

§tensor_name: String

The name of the tensor.

§path: PathBuf

The path that failed.

§

TensorWrongSize

The tensor tensor_name did not match its expected size.

Fields

§tensor_name: String

The name of the tensor.

§path: PathBuf

The path that failed.

§

UnsupportedElementType

The tensor tensor_name did not have the expected format type.

Fields

§tensor_name: String

The name of the tensor.

§ftype: u32

The format type that was encountered.

§path: PathBuf

The path that failed.

§

InvariantBroken

An invariant was broken.

This error is not relevant unless loader2 is being used.

Fields

§path: Option<PathBuf>

The path that failed.

§invariant: String

The invariant that was broken.

§

ModelNotCreated

The model could not be created.

This implies that there were no tensors in the model to be loaded.

This error is not relevant unless loader2 is being used.

Fields

§path: PathBuf

The path that failed.

§

MultipartNotSupported

Multiple parts of the model were found.

Multi-part models are not supported. Please convert the model to a single part.

Fields

§paths: Vec<PathBuf>

The paths that were found.
