I feel confused about data_utils.read_sparse_file function

[xuehuachunsheng]

When I run
true_labels = data_utils.read_sparse_file('Sandbox/Data/EUR-Lex/tst_X_Y.txt')
It raise an exception that ValueError: buffer size must be a multiple of element size from sparse.py line 257,
i.e., indices = np.frombuffer(ind, np.int64)
I see that ind is an array that with typecode = 'l', it seems that the each element in ind takes 4 bytes, according to https://docs.python.org/3/library/array.html.

So I am confused that why loading frombuffer with dtype np.int64?

My machine is 64bit OS.
Python is the version 3.8.8.
