Struct tfrecord::dataset::DatasetInit

pub struct DatasetInit {
    pub check_integrity: bool,
    pub max_open_files: Option<NonZeroUsize>,
    pub max_workers: Option<NonZeroUsize>,
}

The dataset initializer.

Fields

check_integrity: bool

Verify the checksum or not.

max_open_files: Option<NonZeroUsize>

Maximum number of open files.

Limit the number of open files if it is Some(_) It has no limit if it is None.

max_workers: Option<NonZeroUsize>

Maximum number of concurrent workers.

If it is None, it defaults to num_cpus::get.

Implementations

impl DatasetInit

pub async fn from_prefix(self, prefix: &str) -> Result<Dataset, Error>

Open TFRecord files by a path prefix.

If the path ends with “/”, it searchs for all files under the directory. Otherwise, it lists the files with the path prefix. The enumerated paths will be sorted in alphabetical order.

pub async fn from_paths<P>(self, paths: &[P]) -> Result<Dataset, Error> where
    P: AsRef<Path>, 

Open TFRecord files by a set of path.

It assumes every path is a TFRecord file, otherwise it returns error. The order of the paths affects the order of record indexes..
