Dataset prefetch tensorflow

Web在TensorFlow的數據集API中,我們可以使用dataset.prefetch(buffer_size=xxx)來預加載其他批次的數據,而GPU正在處理當前批次的數據,因此,我可以充分利用GPU。 我將使用Keras,並想知道 keras 是否有類似的API供我充分利用GPU而不是串行執行:讀取批次0->處理批次0->讀取 ... WebMay 15, 2024 · The tf.data API provides the tf.data.Dataset.prefetch transformation. It can be used to decouple the time when data is produced from the time when data is consumed. In particular, the transformation uses a background thread and an internal buffer to prefetch elements from the input dataset ahead of the time they are requested.
