通过NumPy的np.flip()函数可以轻易地翻转数组。 importnumpyasnp# 使用NumPy的flip函数my_array=np.array([[1,2,3],[4,5,6]])flipped_array=np.flip(my_array)print(flipped_array)# 输出:# [[6 5 4]# [3 2 1]] 1. 2. 3. 4. 5. 6. 7. 8. 9. flip的应用场景 数据处理:在数据处理中,...

torch.eq(input, other, *, out=None) 1 Parameters(参数): input :必须是一个Tensor,该张量用于比较 other :可以是一个张量Tensor,也可以是一个值value return(返回值):返回一个Boolean类型的张量,对两个张量Tensor进行逐元素的比较,若相同位置的两个元素相同,则返回True;若不同,返回False。 神经网络 网络...

In Python, boolean values are either True or False. Such as flip a coin to select either coin head and tail randomly. Let’s see how to choose a random boolean value, either True or False Example: importrandom res = random.choice([True,False]) ...
参数字符串列表(动态对象),第一个参数为当前程序主文件的绝对路径或空字符串,如果在命令提示符界面给``Python``文件传了参数(不同的参数以空格分隔,无论传入的时候写的是什么类型,最终都会转成字符串),可以在这里面获取(从第二个位置开始),比如命令提示符中运行``“``python main.py 111 aaa``”``,那``...
For example, a Boolean value like True or False is read-only, but you’ll find both mutable and immutable sequences in Python:A Python list represents a mutable sequence of arbitrary elements. A Python string is an immutable sequence of characters....
