I mainly took and modified the build_imagenet_data.py script from tensorflow’s inception model code. The script splits the training set (1,281,167 images) into 1,024 shards, and the validation set (50,000 images) into 128 shards. When done, each shard file would contain roughly the same number of jpg files. The image data in the shard files

2021-03-21 · tf.math.reduce_any ( input_tensor, axis=None, keepdims=False, name=None ) Reduces input_tensor along the dimensions given in axis . Unless keepdims is true, the rank of the tensor is reduced by 1 for each of the entries in axis, which must be unique. If keepdims is true, the reduced dimensions are retained with length 1.

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.

Which version of tensorflow your code ran? I ran it under version 1.14.0, but it has some traceback.

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.

With map_and_batch I just see lower numbers for GPU utilisation and even reaching zero at times. I tried increasing the prefetch to 4 to make up for this, but no improvement. Here I ran with the first input pipeline for a bit and then with the map_and_batch.
