class AlbumDataset : public mindspore::dataset::Dataset

A source dataset for reading and parsing Album dataset.

Public Functions

AlbumDataset(const std::vector<char> &dataset_dir, const std::vector<char> &data_schema, const std::vector<std::vector<char>> &column_names, bool decode, const std::shared_ptr<Sampler> &sampler, const std::shared_ptr<DatasetCache> &cache)

Constructor of AlbumDataset.

Parameters

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

  • data_schema – [in] Path to dataset schema file.

  • column_names – [in] Column names used to specify columns to load, if empty, will read all columns (default = {}).

  • decode – [in] The option to decode the images in dataset (default = false).

  • sampler – [in] Shared pointer to a sampler object used to choose samples from the dataset. If sampler is not given, a RandomSampler will be used to randomly iterate the entire dataset (default = RandomSampler()).

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

AlbumDataset(const std::vector<char> &dataset_dir, const std::vector<char> &data_schema, const std::vector<std::vector<char>> &column_names, bool decode, const Sampler *sampler, const std::shared_ptr<DatasetCache> &cache)

Constructor of AlbumDataset.

Parameters

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

  • data_schema – [in] Path to dataset schema file.

  • column_names – [in] Column names used to specify columns to load.

  • decode – [in] The option to decode the images in dataset.

  • sampler – [in] Raw pointer to a sampler object used to choose samples from the dataset.

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

  • column_names – [in] Column names used to specify columns to load.

  • decode – [in] The option to decode the images in dataset.

  • sampler – [in] Sampler object used to choose samples from the dataset.

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