ValueError：设置具有序列的数组元素

此Python代码：

import numpy as p

def firstfunction(): UnFilteredDuringExSummaryOfMeansArray = [] MeanOutputHeader=['TestID','ConditionName','FilterType','RRMean','HRMean', 'dZdtMaxVoltageMean','BZMean','ZXMean','LVETMean','Z0Mean', 'StrokeVolumeMean','CardiacOutputMean','VelocityIndexMean'] dataMatrix = BeatByBeatMatrixOfMatrices[column] roughTrimmedMatrix = p.array(dataMatrix[1:,1:17])

trimmedMatrix = p.array(roughTrimmedMatrix,dtype=p.float64)  #ERROR THROWN HERE


myMeans = p.mean(trimmedMatrix,axis=0,dtype=p.float64)
conditionMeansArray = [TestID,testCondition,'UnfilteredBefore',myMeans[3], myMeans[4], 
                       myMeans[6], myMeans[9], myMeans[10], myMeans[11], myMeans[12],
                       myMeans[13], myMeans[14], myMeans[15]]
UnFilteredDuringExSummaryOfMeansArray.append(conditionMeansArray)
secondfunction(UnFilteredDuringExSummaryOfMeansArray)
return

def secondfunction(UnFilteredDuringExSummaryOfMeansArray): RRDuringArray = p.array(UnFilteredDuringExSummaryOfMeansArray,dtype=p.float64)[1:,3] return

firstfunction() 引发此错误信息：

File "mypath\mypythonscript.py", line 3484, in secondfunction RRDuringArray = p.array(UnFilteredDuringExSummaryOfMeansArray,dtype=p.float64)[1:,3] ValueError: setting an array element with a sequence. 谁能告诉我该怎么办才能解决上面破碎的代码中的问题，以便停止抛出错误消息？

编辑： 我做了一个打印命令来获取矩阵的内容，这就是它打印出来的内容：

UnFilteredDuringExSummaryOfMeansArray为：
