Here's my code:
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:
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!)
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
