Attributes

num_features

add_token(token)

Add token to the tokenizer :param token: token to be added to the tokenizer :type token: str

create_dataset(params)

Creates HDF5 dataset from given parameters.

Parameters

• files (list) – List of files to process.

• process_no (int) – process id

Returns

Dictionary containing results of execution, specifically as number of

processed, discarded, and successful files as well as number of examples.

get_vocab_size()

Get tokenizer vocabulary size :returns: text to tokenize :rtype: vocab_size (int)

seed_runs(rank=0)

Set seed for run based on user provided seed and rank.

Parameters

rank (int) – Rank to set, based on process number for execution. Defaults to 0.

Returns

Object of type random.Random, with seed set.

write_hdf5_file(file_path, files, rng, n_examples, chunks, dtype='i4', compression='gzip')

Write data to HDF5 file.

Parameters

• file_path (string) – HDF5 file path.

• files (sequence) – List of lists containing tokenized data to write.

• rng (random.Random obj) – Instance of random object, with states set.

• n_examples (int) – Number of examples that will be written in the file.

• chunks (tuple or bool) – Chunk shape, or True to enable auto-chunking.

• dtype (string) – Data type for the HDF5 dataset.

• compression (string) – Compression strategy.

write_hdf5_files(files, start_number, write_remainder=False, process_number=None, rng=<random.Random object>)

Writes a list of files to HDF5.

Parameters

• files (sequence) – List of lists containing tokenized data to write.

• start_number (int) – Continual count of HDF5 files written out.

• write_remainder (bool) – Write out remaining data from files, if files per record is not met. Defaults to False.

• process_number (int) – Process number for execution. Defaults to None.

• rng (random.Random obj) – Instance of random object, with states set. Defaults to new instance created for write.

Returns

Continual count of HDF5 files written out. remainder (list): Remaining sequences not written out, if length of

files to write is greater than the file per record.

Return type

start_number (int)
