AttributeError: 'tuple' object has no attribute 'shape'
提问by Ferial Mohammed
So I have been writing a code to standardize the elements of a matrix and the function I used is as follows:
所以我一直在写代码来对矩阵的元素进行标准化，我使用的函数如下：
def preprocess(Data):
if stdn ==True:
st=np.empty((Data.shape[0],Data.shape[1]))
for i in xrange(0,Data.shape[0]):
st[i,0]=Data[i,0]
for i in xrange(1,Data.shape[1]):
st[:,i]=((Data[:,i]-np.min(Data[:,i]))/(np.ptp(Data[:,i])))
np.random.shuffle(st)
return st
else:
return Data
It works very well outside the class but when used inside of it it gives me this error:
它在课堂外工作得很好，但在课堂内使用时，它给了我这个错误：
AttributeError: 'tuple' object has no attribute 'shape'
Any idea on how I can fix it?? P.S. This is a KNN classification code
关于如何修复它的任何想法？PS这是一个KNN分类代码

According to the error you posted, Datais of type tuple and there is no attribute shapedefined for data. You could try casting Datawhen you call your preprocessfunction, e.g.:
根据您发布的错误，Data是元组类型，并且没有shape为数据定义属性。您可以Data在调用preprocess函数时尝试强制转换，例如：
preprocess(numpy.array(Data))
