Function Documentation

inline std::shared_ptr<DBpediaDataset> mindspore::dataset::DBpedia(const std::string &dataset_dir, const std::string &usage = "all", int64_t num_samples = 0, ShuffleMode shuffle = ShuffleMode::kGlobal, int32_t num_shards = 1, int32_t shard_id = 0, const std::shared_ptr<DatasetCache> &cache = nullptr)

Function to create a DBpediaDataset.

Note

The generated dataset has three columns [“class”, “title”, “content”].

Parameters

  • dataset_dir – [in] Path to the root directory that contains the dataset.

  • usage – [in] Part of dataset of DBpedia, can be “train”, “test” or “all” (default = “all”).

  • 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).

Returns

Shared pointer to the DBpediaDataset
