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).

- 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).
