1) Write a function reverse(A) which takes a matrix A of arbitrary dimensions as input and returns a matrix B consisting of the columns of A in reverse order. Thus for example, if A = 1 2 3 then B = 3 2 1 4 5 6 6 5 4 7 8 9 9 8 7 Write a main program to call reverse(A) for the matrix A = magic(5). Print to the screen both A and reverse(A). 2) Write a program which accepts an input k from the keyboard, and which prints out the smallest fibonacci number that is at least as large as k. The program should also print out its position in the fibonacci sequence. Here is a sample of input and output: Enter k>0: 100 144 is the smallest fibonacci number greater than or equal to 100. It is the 12th fibonacci number.

这个错误是由于输入的张量维度不匹配引起的。根据错误信息来看，你期望输入的张量最后一个维度大小为2，但实际上它的大小为5。要解决这个问题，你可以检查一下输入张量的维度和大小，确保它们与期望的匹配。你可以使用`torch.Size()`函数来获取张量的维度信息，并使用`.size()`方法获取具体的大小。另外，也请注意确认你的输入和模型的期望输入是一致的。有时候输入数据的维度会因为数据处理或者模型定义的不同而发生变化。
