image = PIL.Image.open(file_name) lst.append(np.array(image)) arr = numpy.array(lst) 即,在list中的元素都已转化为numpy.array,而非直接的Image对象。
result=py.numpy.array(matarray); elseiflength(data_size)==2 % A transpose operation is required either in Matlab, or in Python due % to the difference between row major and column major ordering transpose=matarray'; % Pass the array to Python as a vector, and then reshape to the cor...
2. Convert List to Array Using array module You can use the built-inarray()function provided by the array module to create an array from a list or atuple. This is a convenient and efficient way to handle arrays in Python. To create an array of integers using thearray()function, you c...
