Public Functions

TextFileDataset(const std::vector<std::vector<char>> &dataset_files, int64_t num_samples, ShuffleMode shuffle, int32_t num_shards, int32_t shard_id, const std::shared_ptr<DatasetCache> &cache)

Constructor of TextFileDataset.

Parameters

  • dataset_files – [in] List of files to be read to search for a pattern of files. The list will be sorted in a lexicographical order.

  • num_samples – [in] The number of samples to be included in the dataset (Default = 0 means all samples).

  • shuffle – [in] The mode for shuffling data every epoch (Default=ShuffleMode.kGlobal). Can be any of: ShuffleMode.kFalse - No shuffling is performed. ShuffleMode.kFiles - Shuffle files only. ShuffleMode.kGlobal - Shuffle both the files and samples.

  • num_shards – [in] Number of shards that the dataset should be divided into (Default = 1).

  • shard_id – [in] The shard ID within num_shards. This argument should be specified only when num_shards is also specified (Default = 0).

  • cache – [in] Tensor cache to use (default=nullptr which means no cache is used).
