Following the below example, first, you can convert the list into a NumPy array using thenp.array()function. Then you can use theshapethe attribute of the NumPy array to get the shape of the array as a tuple of integers. Finally, you can access the tuple’s elements to get the list...
img_w = img.shape[1] print(img_w) print(img_h) # 沿着横纵轴放大1.6倍,然后平移(-50,-100),最后沿原图大小截取,等效于裁剪并放大 M_crop_elephant = np.array([ [1.6, 0, -50], [0, 1.6, -100] ], dtype=np.float32) dog_gain = cv2.warpAffine(img, M_crop_elephant, (img_w, img...
Sometimes, you need to get the number of elements contained in these objects. When using the NumPy library, you can find the shape of an array using the.shapeproperty: importnumpyasnpmy_array=np.array([[1,2,3],[1,2,3]])print(my_array.shape) Output: (2, 3) Theshapeproperty return...

array = np.array([[1,3,6],[9,12,15],[20,22,25]]) result = array.shape 2. Use NumPy.size to Get Length You can usendarray.sizeproperty to get the total number of elements (length) in a NumPy array. Let’screate a NumPy arrayand use this to get the number of elements from...

size:int or tuple of ints 输出的shape,默认为None,只输出一个值💥(这个很重要!需要几个随机数,size就写几,否则就生成一个数分别加到nparray里了…) 注意区分两者不同 两个库中randint()函数生成整数的范围不同! numpy库中与原函数有相同功能的函数是numpy.random.random_integers(该函数在最新的numpy版本...
