class espnet2.train.dataset.H5FileWrapper(path: str)

Bases: object

A wrapper class for handling HDF5 files.

This class provides a convenient interface for reading data from an HDF5 file using the h5py library. It allows users to access datasets stored in the file in a straightforward manner.

path

The file path to the HDF5 file.

• Type: str

h5_file

The opened HDF5 file.

• Type: h5py.File

• Parameters:path (str) – The path to the HDF5 file to be opened.

Examples

>>> wrapper = H5FileWrapper('data.h5')
>>> print(len(wrapper))  # Output the number of datasets in the file
>>> data = wrapper['dataset_name']  # Access a specific dataset
>>> print(data)  # Print the data from the dataset

• Returns: This class does not return any value upon initialization.
• Return type: None
• Raises:
  • KeyError – If the requested dataset key does not exist in the file.
  • OSError – If the file cannot be opened or read.

NOTE

This class only supports read operations. If you need to write to an HDF5 file, consider using h5py directly.
