格式化输出：默认风格

[ 91,   2,  79, 179,  52, 205;
 236,   8, 181, 239,  26, 248;
 207, 218,  45, 183, 158, 101]


格式化输出：Python风格

[[[ 91,   2,  79], [179,  52, 205]],
 [[236,   8, 181], [239,  26, 248]],
 [[207, 218,  45], [183, 158, 101]]]


格式化输出：CSV风格

 91,   2,  79, 179,  52, 205
236,   8, 181, 239,  26, 248
207, 218,  45, 183, 158, 101


格式化输出：NumPy风格

array([[[ 91,   2,  79], [179,  52, 205]],
       [[236,   8, 181], [239,  26, 248]],
       [[207, 218,  45], [183, 158, 101]]], dtype='uint8')


格式化输出：c风格

{ 91,   2,  79, 179,  52, 205,
 236,   8, 181, 239,  26, 248,
 207, 218,  45, 183, 158, 101}
