Defined in File datasets.h
Function Documentation
Function to create a FlickrDataset.
Note
The generated dataset has two columns [“image”, “annotation”]
- Parameters
dataset_dir – [in] The dataset dir to be read
annotation_file – [in] The annotation file to be read
decode – [in] Decode the images after reading (default=false).
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).
- Returns
Shared pointer to the current FlickrDataset
Example/* Define dataset path and MindData object */ std::string dataset_path = "/path/to/flickr30k_dataset_directory"; std::string file_path = "/path/to/token_file"; std::shared_ptr<Dataset> ds = Flickr(dataset_path, file_path); /* Create iterator to read dataset */ std::shared_ptr<Iterator> iter = ds->CreateIterator(); std::unordered_map<std::string, mindspore::MSTensor> row; iter->GetNextRow(&row); /* Note: In FLICKR dataset, each dictionary has keys "image" and "annotation" */ auto image = row["image"];
