Function Documentation

inline std::shared_ptr<SogouNewsDataset> mindspore::dataset::SogouNews(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 SogouNewsDataset.

Note

This dataset includes polarity and full, which can be read according to your own needs.

Note

The generated dataset has three columns [“index”, “title” , “content”]. Their types are all string.

Parameters

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

  • usage – [in] Part of dataset of SogouNews, can be “train”, “test” or “all” data (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 SogouNewsDataset.
