在python中随机随机播放稀疏矩阵
问题描述:
有没有一种简单的方法可以在python中随机播放稀疏矩阵?
is there an easy way to shuffle a sparse matrix in python?
这是我改组非稀疏矩阵的方式:
This is how I shuffle a non-sparse matrix:
index = np.arange(np.shape(matrix)[0])
np.random.shuffle(index)
return matrix[index]
我该如何用numpy稀疏处理呢?
How can I do it with numpy sparse?
答
好,找到了.稀疏格式在打印输出中看起来有些混乱.
Ok, found it. The sparse format looks a bit confusing in the print-out.
index = np.arange(np.shape(matrix)[0])
print index
np.random.shuffle(index)
return matrix[index, :]
