Question

我不明白数组的含义是什么？数组是关于图像数据的

我得到的输出结果：如图所示

我通过以下代码读取数据：

# function:load single batch of cifar 
def load_CIFAR_batch(filename):
  with open(filename, 'rb') as f:
    datadict = pk.load(f,encoding='latin1')
    X = datadict['data']
    Y = datadict['labels']
    print(X)
    print(5)
    X = X.reshape(10000, 3, 32, 32).transpose(0,2,3,1).astype("float")
    print(X)
    print(6)
    Y = np.array(Y)
    return X, Y

# function:load all data of cifar 
def load_CIFAR10(ROOT):
  xs = []
  ys = []
  for b in range(1,2):
    f = os.path.join(ROOT, 'data_batch_%d' % (b, ))
    X, Y = load_CIFAR_batch(f)
    xs.append(X)
    ys.append(Y)   

  Xtr = np.concatenate(xs)
  Ytr = np.concatenate(ys)

  del X, Y
  Xte, Yte = load_CIFAR_batch(os.path.join(ROOT, 'test_batch'))
  return Xtr, Ytr, Xte, Yte

if __name__ == "__main__":
  cifar10_dir = "/home/tenglong/tenglong/cs231n/datasets/cifar-10-batches-py"
  load_CIFAR10(cifar10_dir)

我得到的结果，但我不知道这是什么意思
