问题描述

我有一个存储numpy数组的h5py文件，但是尝试用我记得的数据集名称打开它时却得到了Object doesn't exist error，所以有什么办法可以列出该文件具有哪些数据集?

I have a h5py file storing numpy arrays, but I got Object doesn't exist error when trying to open it with the dataset name I remember, so is there a way I can list what datasets the file has?

   with h5py.File('result.h5','r') as hf:
        #How can I list all dataset I have saved in hf?

推荐答案

您必须使用keys方法.这将为您提供数据集和组名的unicode字符串列表. 例如:

You have to use the keys method. This will give you a List of unicode strings of your dataset and group names. For example:

Datasetnames=hf.keys()

另一种基于gui的方法是使用HDFView. https://support.hdfgroup.org/products/java/release/download.html
