正确的方法是使用 np.array_equal ,它检查形状和元素是否相等: np.array_equal(x,y) # False 对于浮点数, np.allclose 更适合,因为它允许控制比较结果的相对和绝对容差。这是一个例子: x = np.random.random((400,34)) y = x.round(6) np.array_equal(x,y) # False np.allclose(x,y) # False...

array([1, 2, 3, 4]) Example of an Array operation In the below example, you add two numpy arrays. The result is an element-wise sum of both the arrays. import numpy as np array_A = np.array([1, 2, 3]) array_B = np.array([4, 5, 6]) print(array_A + array_B) ...

With one-dimension arrays, we can index a given element by its position, keeping in mind that indices start at 0. 使用一维数组,我们可以根据给定元素的位置对其进行索引,记住索引从0开始。 With two-dimensional arrays, the first index specifies the row of the array and the second index 对于二维数...
大家好,我是极智视界,本文介绍一下 python 和 cpp 实现 TensorRT elementWise 层。 elementWise 算子指的是需要逐位运行的 op,具有十分丰富的元素间计算,如元素加、元素点乘、元素减、取极值等。这里结合 TensorRT 的实现来说,主要包括 python 实现 和 cpp 实现。
array1 = np.array([[1, 2, 3], [4, 5, 6]]) array2 = np.array([[7, 8, 9], [10, 11, 12]]) # 加法 addition_array = array1 + array2 print(f"元素级加法:\n{addition_array}") # 结果: # [[ 8 10 12] # [14 16 18]] # 减法 subtraction_array = array1 - array2 p...
