Function Documentation

inline std::shared_ptr<ImageFolderDataset> mindspore::dataset::ImageFolder(const std::string &dataset_dir, bool decode, const std::reference_wrapper<Sampler> sampler, const std::set<std::string> &extensions = {}, const std::map<std::string, int32_t> &class_indexing = {}, const std::shared_ptr<DatasetCache> &cache = nullptr)

Function to create an ImageFolderDataset.

Note

A source dataset that reads images from a tree of directories. All images within one folder have the same label. The generated dataset has two columns [“image”, “label”].

Parameters

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

  • decode – [in] A flag to decode in ImageFolder.

  • sampler – [in] 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).

Returns

Shared pointer to the ImageFolderDataset.
