Generic model classes

class optimum.intel.openvino.modeling_base.OVBaseModel

< >

( model: Model config: PretrainedConfig = None device: str = 'CPU' dynamic_shapes: bool = True ov_config: typing.Optional[typing.Dict[str, str]] = None model_save_dir: typing.Union[str, pathlib.Path, optimum.intel.openvino.utils.TemporaryDirectory, NoneType] = None quantization_config: typing.Union[optimum.intel.openvino.configuration.OVWeightQuantizationConfig, typing.Dict, NoneType] = None **kwargs )

Base OVModel class.

from_pretrained

< >

( model_id: typing.Union[str, pathlib.Path] export: bool = False force_download: bool = False use_auth_token: typing.Union[str, bool, NoneType] = None token: typing.Union[str, bool, NoneType] = None cache_dir: str = '/root/.cache/huggingface/hub' subfolder: str = '' config: typing.Optional[transformers.configuration_utils.PretrainedConfig] = None local_files_only: bool = False trust_remote_code: bool = False revision: typing.Optional[str] = None **kwargs )

Parameters

  • model_id (Union[str, Path]) — Can be either:
    • A string, the model id of a pretrained model hosted inside a model repo on huggingface.co. Valid model ids can be located at the root-level, like bert-base-uncased, or namespaced under a user or organization name, like dbmdz/bert-base-german-cased.
    • A path to a directory containing a model saved using ~OptimizedModel.save_pretrained, e.g., ./my_model_directory/.
  • export (bool, defaults to False) — Defines whether the provided model_id needs to be exported to the targeted format.
  • force_download (bool, defaults to True) — Whether or not to force the (re-)download of the model weights and configuration files, overriding the cached versions if they exist.
  • use_auth_token (Optional[Union[bool,str]], defaults to None) — Deprecated. Please use the token argument instead.
  • token (Optional[Union[bool,str]], defaults to None) — The token to use as HTTP bearer authorization for remote files. If True, will use the token generated when running huggingface-cli login (stored in huggingface_hub.constants.HF_TOKEN_PATH).
  • cache_dir (Optional[str], defaults to None) — Path to a directory in which a downloaded pretrained model configuration should be cached if the standard cache should not be used.
  • subfolder (str, defaults to "") — In case the relevant files are located inside a subfolder of the model repo either locally or on huggingface.co, you can specify the folder name here.
  • config (Optional[transformers.PretrainedConfig], defaults to None) — The model configuration.
  • local_files_only (Optional[bool], defaults to False) — Whether or not to only look at local files (i.e., do not try to download the model).
  • trust_remote_code (bool, defaults to False) — Whether or not to allow for custom code defined on the Hub in their own modeling. This option should only be set to True for repositories you trust and in which you have read the code, as it will execute code present on the Hub on your local machine.
  • revision (Optional[str], defaults to None) — The specific model version to use. It can be a branch name, a tag name, or a commit id, since we use a git-based system for storing models and other artifacts on huggingface.co, so revision can be any identifier allowed by git.

Instantiate a pretrained model from a pre-trained model configuration.

OVModelForAudioXVector

class optimum.intel.OVModelForAudioXVector

< >

( model: Model config: PretrainedConfig = None **kwargs )

Parameters

  • model (openvino.runtime.Model) — is the main class used to run OpenVINO Runtime inference.
  • config (transformers.PretrainedConfig) — PretrainedConfig is the Model configuration class with all the parameters of the model. Initializing with a config file does not load the weights associated with the model, only the configuration. Check out the ~intel.openvino.modeling.OVBaseModel.from_pretrained method to load the model weights.
  • device (str, defaults to "CPU") — The device type for which the model will be optimized for. The resulting compiled model will contains nodes specific to this device.
  • dynamic_shapes (bool, defaults to True) — All the model’s dimension will be set to dynamic when set to True. Should be set to False for the model to not be dynamically reshaped by default.
  • ov_config (Optional[Dict], defaults to None) — The dictionnary containing the informations related to the model compilation.
  • compile (bool, defaults to True) — Disable the model compilation during the loading step when set to False. Can be useful to avoid unnecessary compilation, in the case where the model needs to be statically reshaped, the device modified or if FP16 conversion is enabled.

( input_values: typing.Optional[torch.Tensor] = None attention_mask: typing.Optional[torch.Tensor] = None **kwargs )

Parameters

  • input_values (torch.Tensor of shape (batch_size, sequence_length)) — Float values of input raw speech waveform.. Input values can be obtained from audio file loaded into an array using AutoFeatureExtractor.

The OVModelForAudioXVector forward method, overrides the __call__ special method.

Although the recipe for forward pass needs to be defined within this function, one should call the Module instance afterwards instead of this since the former takes care of running the pre and post processing steps while the latter silently ignores them.

Example of Audio XVector:

>>> from optimum.intel import OVModelForAudioXVector
>>> from datasets import load_dataset
>>> import torch

>>> dataset = load_dataset("hf-internal-testing/librispeech_asr_demo", "clean", split="validation")

>>> sampling_rate = dataset.features["audio"].sampling_rate

>>> feature_extractor = AutoFeatureExtractor.from_pretrained("anton-l/wav2vec2-base-superb-sv")
>>> model = OVModelForAudioXVector.from_pretrained("anton-l/wav2vec2-base-superb-sv", export=True)

>>> # audio file is decoded on the fly
>>> inputs = feature_extractor(
...     [d["array"] for d in dataset[:2]["audio"]], sampling_rate=sampling_rate, return_tensors="pt", padding=True
... )
>>>     embeddings = model(**inputs).embeddings

>>> embeddings = torch.nn.functional.normalize(embeddings, dim=-1).cpu()

>>> cosine_sim = torch.nn.CosineSimilarity(dim=-1)
>>> similarity = cosine_sim(embeddings[0], embeddings[1])
>>> threshold = 0.7
