Python：将numpy矩阵映射到矩阵

Question

我需要一些结构，如：

from numpy import *

myDict = {
    matrix([ 0,0,0 ]): matrix([ 0,0,0 ]),
    matrix([ 0,0,1 ]): matrix([ 0,1,0 ]),
    matrix([ 0,1,0 ]): matrix([ 0,1,1 ]),
    matrix([ 0,1,1 ]): matrix([ 1,0,0 ]),
    matrix([ 1,0,0 ]): matrix([ 1,0,1 ]),
    matrix([ 1,0,1 ]): matrix([ 1,1,0 ]),
    matrix([ 1,1,0 ]): matrix([ 0,0,1 ]),
    matrix([ 1,1,1 ]): matrix([ 1,1,1 ]),
}

但是，当我调用 myDict [matrix（[0,1,1]）] 时，它会引发KeyError。 那么，如何在Python中实现矩阵到矩阵的映射？
