A step-by-step illustrated guide on how to get the indices of the N largest values in a NumPy array in multiple ways.
If you want a single number for the number of dimensions like 2, 3, 4, etc., then just use tf.rank(). But, if you want the exact shape of the tensor then use tensor.get_shape() with tf.Session() as sess: arr = tf.random_normal(shape=(10, 32, 32, 1...
Get the Number of Rows in NumPy Array Using the array.shape PropertyThe array.shape property in NumPy is used to obtain the dimensions (shape) of a NumPy array. It returns a tuple that specifies the number of elements along each axis of the array....
append(np.array([obj.l,obj.w,obj.h])) #将长宽高,和类型,以及旋转角度的信息写入列表 type_list.append(obj.type) ry_list.append(obj.ry) with open('box3d_dimensions.pickle','wb') as fp: #将列表里的信息写入.pikle文件,应该是用来学习的数据 pickle.dump(type_list, fp) pickle.dump(...
Swapping the dimensions of a NumPy array Good ways to 'expand' a NumPy ndarray Simplest way to extend a NumPy array in 2 dimensions Find matching rows in 2 dimensional NumPy array Why in NumPy 'nan == nan' is False while nan in [nan] is True?
NumPy proposes a way to get the index of the maximum value of an array via np.argmax. I would like a similar thing, but returning the indexes of the N maximum values. For instance, if I have an array, [1, 3, 2, 4, 5], then nargmax(array, n=3) would return the indices [...

A step-by-step illustrated guide on how to get N random rows from a NumPy array in Python in multiple ways.
X: This is the array or matrix whose dimensions you want to retrieve. size(): This is the MATLAB function that returns the sizes of the dimensions ofX. n: This indicates the number of dimensions of the arrayX. IfXis a 2D matrix,nwill be 2. In this case,d1will represent the number...
