Public Functions

STL10Dataset(const std::vector<char> &dataset_dir, const std::vector<char> &usage, const std::shared_ptr<Sampler> &sampler, const std::shared_ptr<DatasetCache> &cache)

Constructor of STL10Dataset.

Parameters

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

• usage – [in] Part of dataset of STL10, can be “train”, “test”, “unlabeled”, “train+unlabeled” or “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.

• cache – [in] Tensor cache to use.
