class CelebADataset : public mindspore::dataset::Dataset

A source dataset for reading and parsing CelebA dataset.

Public Functions

CelebADataset(const std::vector<char> &dataset_dir, const std::vector<char> &usage, const std::shared_ptr<Sampler> &sampler, bool decode, const std::set<std::vector<char>> &extensions, const std::shared_ptr<DatasetCache> &cache)

Constructor of CelebADataset.

Parameters

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

  • usage – [in] One of “all”, “train”, “valid” or “test” (default = “all”).

  • 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()).

  • decode – [in] Decode the images after reading (default=false).

  • extensions – [in] Set of file extensions to be included in the dataset (default={}).

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

Constructor of CelebADataset.

Parameters

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

  • usage – [in] One of “all”, “train”, “valid” or “test”.

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

  • decode – [in] Decode the images after reading (default=false).

  • extensions – [in] Set of file extensions to be included in the dataset (default={}).

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