Python Numpy TypeError: ufunc 'isfinite' not supported for the input types

Question

Here\'s my code:

def topK(dataMat,sensitivity):
    meanVals = np.mean(dataMat, axis=0)
    meanRemoved = dataMat - meanVals
    covMat = np.cov(meanRemoved,         


        

Answer 1

Your array has a dtype of object, but this should be some floating point dtype. Use e.g.

covMat = np.array(covMat, dtype=float)

to convert the dtype
