# 定义NPZ文件的路径 file_path = "path/to/your/file.npz" # 使用np.load()函数打开NPZ文件 data = np.load(file_path) 四、访问NPZ文件中的数组 一旦你成功地加载了NPZ文件,你可以通过查看类似字典对象的.files属性或.keys()方法,获取NPZ文件中的所有数组的名称。然后,你可以使用这些名称作为键来访问相...
Use the `keys()` method of the dictionary object to view the names of all the arrays in the npz file. section Get a specific array Use the keys of the dictionary object to access the specific arrays you are interested in. section Perform further operations with the arrays Use the retrieve...

注意 *:f属性没有记录在load的docstring中。当load读取npz文件时,它返回class NpzFile的示例。这个类可以作为numpy.lib.npyio.NpzFile使用。NpzFile类的文档字符串描述了f属性。(在撰写本文时,类的源代码可以在这里找到。尝试
If npz_keys is not given,NumpyReaderassumes variables in .npz files to be named arr_0, arr_1,... This may or may not be true. It would be better to use the variable names from the file like so: npz_keys=self.npz_keysifself.npz_keyselselist(img.keys() )...
