Python Numpy TypeError: ufunc 'isfinite' not supported for the input types
提问by swabygw
Here's my code:
这是我的代码:
def topK(dataMat,sensitivity):
meanVals = np.mean(dataMat, axis=0)
meanRemoved = dataMat - meanVals
covMat = np.cov(meanRemoved, rowvar=0)
eigVals,eigVects = np.linalg.eig(np.mat(covMat))
I get the error in the title on the last line above. I suspect has something to do with the datatype, so, here's an image of the variable and datatype from the Variable Explorer in Spyder:
我在上面最后一行的标题中收到错误消息。我怀疑与数据类型有关,因此,这是来自 Spyder 中的变量资源管理器的变量和数据类型的图像:
I've tried changing np.linalg.eig(np.mat(covMat))to np.linalg.eig(np.array(np.mat(covMat)))and to np.linalg.eig(np.array(covMat)), nothing works. Any ideas? (an example would be great!)
我尝试将np.linalg.eig(np.mat(covMat))更改为np.linalg.eig(np.array(np.mat(covMat)))和np.linalg.eig(np.array(covMat) )),没有任何效果。有任何想法吗?(一个例子会很棒!)

Your array has a dtype
of object
, but this should be some floating point dtype
. Use e.g.
你的数组有一个dtype
of object
,但这应该是一些浮点数dtype
。使用例如
covMat = np.array(covMat, dtype=float)
to convert the dtype
转换 dtype
