我试图在caffe中加载hdf5,它不起作用.我检查了路径,甚至能够使用viewer查看hdf文件.一切都很好,但似乎无法加载.

我使用像这样的python脚本编写hdf5,其中X和标签是numpy数组.

f = h5py.File("facialkp.hd5", "w")
f.create_dataset("data", data=X,  compression="gzip", compression_opts=4)
f.create_dataset("label", data=labels,  compression="gzip", compression_opts=4)

这是整个问题.

解决方法:

解决了 ：)

我创建了一个文本文件,在其中放置了真正的.hd5文件的路径. caffe原型文件指向文本文件,它工作:)

 hdf5_data_param {
   source: "train.txt"
   batch_size: 10
  }

train.txt包含行..
