tensorflow中的数据集类Dataset有一个shuffle方法,用来打乱数据集中数据顺序,训练时非常常用。其中shuffle方法有一个参数buffer_size,非常令人费解,文档的解释如下: buffer_size: A tf.int64 scalar tf.Tensor, representing the number of elements from this dataset from which the new dataset will sample. 1. 你...
In a distributed data processing system with a set of multiple nodes, a first data shuffle memory pool is maintained at a data shuffle writer node, and a second data shuffle memory pool is maintained at a data shuffle reader node. The data shuffle writer node and the data shuffle reader ...

The biggest advantage of using an offsite backup is that you don’t have to worry whether all the data on your computer is really uploading or not. In fact, you don’t need an Internet connection at all for the Mozy data shuffle to work!
dataset = dataset.shuffle(3, reshuffle_each_iteration=True) dataset = dataset.repeat(2) # [1, 0, 2, 1, 2, 0] dataset = tf.data.Dataset.range(3) dataset = dataset.shuffle(3, reshuffle_each_iteration=False) dataset = dataset.repeat(2) ...
Method 2 –Combining RAND Function and Sort Feature to Shuffle Data TheRANDfunction returns evenly distributed random values from0to1. TheSortfeature sorts a range of cells in ascending or descending order according to a specific column. We will combine these 2 functions to shuffle the data. ...
shuffle data持久化在磁盘上,如果一直不清理,磁盘容易被撑爆。那shuffle data什么时候会被清理呢。一般来说可以分成3种场景: 1、spark application主动停止,需要清理该application下所属的全部shuffle data。清理流程如下(本文均以未启用external shuffle service,spark 2.x代码为例): ...
