numpy.float64' object is not iterable

这个错误是因为你试图对一个numpy.float64类型的对象进行迭代操作，但是这种类型的对象是不可迭代的。可能是你在使用for循环或者其他需要迭代操作的语句时，将一个numpy.float64类型的对象作为了迭代对象。你需要检查一下代码，找出这个错误的具体原因，并对代码进行修改。

'numpy.float64' object is not iterable

This error occurs when you try to iterate over a single `numpy.float64` object, which is not iterable. Iteration can only be performed on objects that are collections, such as lists or arrays.

For example, if you have a single `numpy.float64` object `x`, and you try to iterate over it using a loop like this:

for i in x:
    print(i)

you will get the error message:

TypeError: 'numpy.float64' object is not iterable

To fix this error, you can either convert the `numpy.float64` object to a collection, such as a list or an array, or you can use the object directly without iterating over it.

TypeError: 'numpy.float32' object is not iterable

引用\[2\]中提到了一个类似的问题，即在for循环中出现了"numpy.float64 object is not iterable"的错误。这个错误通常是由于尝试对一个浮点数进行迭代操作而导致的。在你的代码中，当x_mat是一维数组时，x_mat\[0\]是一个浮点数，无法进行循环操作，从而导致了这个错误。为了解决这个问题，你可以在循环之前添加一个判断条件，判断x_mat是否为一维数组，如果是，则直接将x_mat赋值给x_norm，否则再进行循环操作。以下是一个可能的解决方案：

if len(x_mat.shape) == 1:
x_norm = x_mat
else:
for i in range(len(x_mat)):
x_norm\[i\] = \[math.atan(temp_x)*2/math.pi for temp_x in x_mat\[0\]\]

这样，当x_mat是一维数组时，直接将x_mat赋值给x_norm，避免了对浮点数进行循环操作，从而解决了这个错误。希望这个解决方案对你有帮助。
