我正在尝试使用numpy在python中使用构建OpenGL纹理,但我遇到了问题,因为我无法预测numpy数组将如何在内存中组织.下面的示例程序(应该按原样运行)说明了我的困惑:
from pylab import *
array_by_hand = array(
[[[1, 2, 3, 4], [1, 2, 3, 4]],
[[1, 2, 3, 4], [1, 2, 3, 4]]], dtype='uint8')
layers = 1 * ones((2, 2)), 2 * ones((2, 2)), 3 * ones((2, 2)), 4 * ones((2, 2))
array_from_layers = dstack(layers)
array_from_layers = array_from_layers.astype('uint8')
print array_by_hand; print
print array_from_layers; print
print ' '.join(x.encode('hex') for x in array_by_hand.data)
print ' '.join(x.encode('hex') for x in array_from_layers.data)
print
print all(array_by_hand == array_from_layers) # True
print str(array_by_hand.data) == str(array_from_layers.data) …
