使用索引从一个NumPy中删除多个元素传递一个包含所有元素的索引的数组,除了要删除的元素的索引,这将从数组中删除该元素。import numpy as np # numpy array arr = np.array([9, 8, 7, 6, 5, 4, 3, 2, 1]) # index array with index of all the elements, except index = 5. # so element at ...
虽然NumPy 数组本身不支持直接移除元素,但你可以通过以下几种方式来实现类似的效果: 使用布尔索引: 你可以通过布尔索引来筛选出不需要移除的元素,从而间接地达到移除元素的效果。 python import numpy as np # 创建一个示例数组 arr = np.array([1, 2, 3, 4, 5]) # 假设要移除元素 3 element_to_remove ...
通过add_constant 添加 constant 算子 constantLayer = network.add_constant([1], np.array([1], dtype=np.float32)) 重设常量数据 constantLayer.weights = data 重设常量形状 constantLayer.shape = data.shape 来看一个实际的例子:import numpy as np from cuda import cudart import tensorrt as trt输入张量...
