Function Documentation

inline std::shared_ptr<CityscapesDataset> mindspore::dataset::Cityscapes(const std::string &dataset_dir, const std::string &usage, const std::string &quality_mode, const std::string &task, bool decode, const std::reference_wrapper<Sampler> &sampler, const std::shared_ptr<DatasetCache> &cache = nullptr)

Function to create a CityscapesDataset.

Note

The generated dataset has two columns [“image”, “task”].

Parameters

• dataset_dir – [in] The dataset dir to be read.

• usage – [in] The type of dataset. Acceptable usages include “train”, “test”, “val” or “all” if quality_mode is “fine” otherwise “train”, “train_extra”, “val” or “all”.

• quality_mode – [in] The quality mode of processed image. Acceptable quality_modes include “fine” or “coarse”.

• task – [in] The type of task which is used to select output data. Acceptable tasks include “instance”, “semantic”, “polygon” or “color”.

• 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).

Returns

Shared pointer to the current CityscapesDataset.
