class Cifar100Dataset : public mindspore::dataset::Dataset 

A source dataset for reading and parsing Cifar100 dataset.

Public Functions

Cifar100Dataset(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 Cifar100Dataset.

Parameters

dataset_dir – [in] Path to the root directory that contains the dataset.
usage – [in] Part of dataset of CIFAR100, can be “train”, “test” or “all” (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()).
cache – [in] Tensor cache to use (default=nullptr which means no cache is used).

Cifar100Dataset(const std::vector<char> &dataset_dir, const std::vector<char> &usage, const Sampler *sampler, const std::shared_ptr<DatasetCache> &cache)

Constructor of Cifar100Dataset.

Parameters

dataset_dir – [in] Path to the root directory that contains the dataset.
usage – [in] Part of dataset of CIFAR100, can be “train”, “test” or “all”.
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).
