scipy.sparse中缺少save_npz方法 [英] save_npz method missing from scipy.sparse
问题描述
我正在python v3.5
中的ubuntu 16.04 64位系统上使用scipy
库的0.17版本.我找不到 scipy库中的.sparse.save_npz 操作,尽管在最新文档中已提及.
I am using 0.17 version of scipy
library on ubuntu 16.04 64-bit system in python v3.5
. I am unable to find scipy.sparse.save_npz operation in the library, although it is mentioned in the latest documentation.
在列出scipy.sparse
对象中的可调用方法时,我得到以下输出:
On listing the callable methods from scipy.sparse
object I am getting the following output:
['SparseEfficiencyWarning',
'SparseWarning',
'Tester',
'bench',
'block_diag',
'bmat',
'bsr_matrix',
'coo_matrix',
'cs_graph_components',
'csc_matrix',
'csr_matrix',
'dia_matrix',
'diags',
'dok_matrix',
'eye',
'find',
'hstack',
'identity',
'issparse',
'isspmatrix',
'isspmatrix_bsr',
'isspmatrix_coo',
'isspmatrix_csc',
'isspmatrix_csr',
'isspmatrix_dia',
'isspmatrix_dok',

'kron',
'kronsum',
'lil_matrix',
'rand',
'random',
'spdiags',
'spmatrix',
'test',
'tril',
'triu',
'vstack']
该列表应包含save_npz
方法,但此方法不存在.如果不建议使用该方法,请告诉我一些保存和加载稀疏矩阵的好方法.
The list should have contained save_npz
method but it is not there. If the method has been deprecated then please tell me some good alternatives for saving and loading sparse matrices.
推荐答案
是的,scipy.sparse.save_npz / load_npz
是版本0.19.0
Yes, scipy.sparse.save_npz / load_npz
are new in version 0.19.0 http://scipy.github.io/devdocs/release.0.19.0.html
