class FlickrDataset : public mindspore::dataset::Dataset

A source dataset for reading and parsing Flickr dataset.

Public Functions

FlickrDataset(const std::vector<char> &dataset_dir, const std::vector<char> &annotation_file, bool decode, const std::shared_ptr<Sampler> &sampler, const std::shared_ptr<DatasetCache> &cache)

Constructor of FlickrDataset.

Parameters

  • dataset_dir – [in] The dataset dir to be read

  • annotation_file – [in] The annotation file to be read

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

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

Constructor of FlickrDataset.

Parameters

  • dataset_dir – [in] The dataset dir to be read

  • annotation_file – [in] The annotation file to be read

  • decode – [in] Decode the images after reading.

  • 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).

FlickrDataset(const std::vector<char> &dataset_dir, const std::vector<char> &annotation_file, bool decode, const std::reference_wrapper<Sampler> sampler, const std::shared_ptr<DatasetCache> &cache)

Parameters

  • dataset_dir – [in] The dataset dir to be read

  • annotation_file – [in] The annotation file to be read

  • decode – [in] Decode the images after reading.

  • 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).
