2018年12月19日 出現這個錯誤的原因極大可能是你正在使用的TensorFlow版本有點低了,將 TensorFlow的版本update到1.10.0版本及其以上就可以解決這個問題 

For instance, on a DGX-1, 80 parallel calls of the map are invoked (vs. 2 for a batch size of 2), which can result in Out Of Memory Segfaults.

Instructions for updating: Use tf.data.Dataset.map(map_func, num_parallel_calls) followed by tf.data.Dataset.batch(batch_size, drop_remainder). 2021-04-01 · Zero-pad the start and end of dimensions [1, , M] of the input according to paddings to produce padded of shape padded_shape.

map ( map_func = parse_fn , num_parallel_calls = FLAGS . num_parallel_calls ) dataset = dataset . batch ( batch_size = FLAGS . batch_size ) The method for reading data from a TensorFlow Dataset varies depending upon which API you are using to build your models. If you are using the keras, then TensorFlow Datasets can be used much like in-memory R matrices and arrays. If you are using the lower-level tensorflow core API then you’ll use explicit dataset iteration functions.

此前,在TensorFlow中读取数据一般有两种方法: 使用placeholder读内存中的数据 出错:module 'tensorflow' has no attribute 'layers' 解决方法:由于已经安装的tensorflow是0.x的版本,0.x版本没有layers模块所以程序出错,需要重新安装tensorflow 1.0以上的版本,即更新tensorflow版本。 查看目前tensorflow版本 pip list 显示:如下图,此时的tensorflow为0.12 1.

Defined in tensorflow/contrib/data/python/ops/batching.py. Fused implementation of map and batch. Maps map_func across batch_size consecutive elements of this dataset and then combines them into a batch. Functionally, it is equivalent to map followed by batch.

map_func横跨dataset的batch_size个连续元素,然后将它们组合成一个batch。. 在功能上,它相当于map 后面跟着batch。.
