<div class =“post-text”itemprop =“text”> <P> 您可以使用 <code> interleave </code> </p> <pre> <code> filenames = [tfrecord_file1, tfrecord_file2] dataset = (Dataset.from_tensor_slices(filenames).interleave(lambda x:TFRecordDataset(x) dataset = dataset.map(parse_fn) ... </code> </pre> <P> 或者你甚至可以尝试并行交错。看到 <a href="https://www.tensorflow.org/api_docs/python/tf/data/TFRecordDataset#interleave" rel="nofollow noreferrer"> https://www.tensorflow.org/api_docs/python/tf/data/TFRecordDataset#interleave </A> <a href="https://www.tensorflow.org/api_docs/python/tf/data/experimental/parallel_interleave" rel="nofollow noreferrer"> https://www.tensorflow.org/api_docs/python/tf/data/experimental/parallel_interleave </A> </p> </DIV>
