我拥有32X32像素RGB图像(4波段)的所有图像。我收到上述错误。我不知道为什么它越界,不是因为图像太多吗?
有谁知道如何解决这个问题?
最佳答案
您正在错误地重塑它。您想修饰ARGB图像,但要将X重塑为reshape(-1,IMG_SIZE,IMG_SIZE,1)
,而应该对4通道图像进行reshape(-1,IMG_SIZE,IMG_SIZE,4)
,并且与test_x变量相同。
编辑部分代码:
X = np.array([i[0] for i in train]).reshape(-1,IMG_SIZE,IMG_SIZE,4)
test_x = np.array([i[0] for i in test]).reshape(-1,IMG_SIZE,IMG_SIZE,4)
