我正在尝试在caffe中加载hdf5，但它无效。我检查了路径，甚至能够使用viewer查看hdf文件。一切都还可以，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，它起作用：）
hdf5_data_param {
source: "train.txt"
batch_size: 10
}
train.txt包含行..
