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。
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...

The easiest way to convert a list to an array is to use the array() function from the array module in Python. The array() function creates an array of specified type and size from a Python list.Following is the code to convert a list to an array using the array() function:...
x_int8 = tf.convert_to_tensor(x, dtype=tf.int8) tf.image.convert_image_dtype(x_int8, dtype=tf.float16, saturate=False) <tf.Tensor:shape=(2,2,3), dtype=float16, numpy= array([[[0.00787,0.01575,0.02362], [0.0315,0.03937,0.04724]], ...
代码(Python3) class Solution: def construct2DArray(self, original: List[int], m: int, n: int) -> List[List[int]]: # 如果长度不等于目标二维数组的大小,则直接返回空数组 if len(original) != m * n: return [] # 定义二维数组 ans: List[List[int]] = [[0] * n for _ in range(...
