class ImageFolderDataset : public mindspore::dataset::Dataset
A source dataset that reads images from a tree of directories.
Public Functions
-
ImageFolderDataset(const std::vector<char> &dataset_dir, bool decode, const std::shared_ptr<Sampler> &sampler, const std::set<std::vector<char>> &extensions, const std::map<std::vector<char>, int32_t> &class_indexing, const std::shared_ptr<DatasetCache> &cache)
Constructor of ImageFolderDataset.
- Parameters
dataset_dir – [in] Path to the root directory that contains the dataset.
decode – [in] A flag to decode in ImageFolder.
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()).extensions – [in] File extensions to be read.
class_indexing – [in] a class name to label map.
cache – [in] Tensor cache to use (default=nullptr which means no cache is used).

Constructor of ImageFolderDataset.
- Parameters
dataset_dir – [in] Path to the root directory that contains the dataset.
decode – [in] A flag to decode in ImageFolder.
sampler – [in] Raw pointer to a sampler object used to choose samples from the dataset.
extensions – [in] File extensions to be read.
class_indexing – [in] a class name to label map.
cache – [in] Tensor cache to use (default=nullptr which means no cache is used).
