'numpy.ndarray' object has no attribute 'values'

提问by T.Setso

I want to shift my time series data, but getting following error:

我想移动我的时间序列数据,但出现以下错误:

AttributeError: 'numpy.ndarray' object has no attribute 'values'

AttributeError: 'numpy.ndarray' 对象没有属性 'values'

Thats my Code:

那是我的代码:

def create_dataset(datasets):
    #series = dataset
    temps = DataFrame(datasets.values)
    dataframes = concat(
        [temps, temps.shift(-1), temps.shift(-2), temps.shift(-3)], axis=1)
    lala = numpy.array(dataframes)
    return lala

    #load
    dataframe = pandas.read_csv('zahlenreihe.csv', index_col=False,   
    engine='python', header=None)
    dataset = dataframe.values
    dataset = dataset.astype('float32')

    #split 
    train_size = int(len(dataset) * 0.70)
    test_size = len(dataset) - train_size
    train, test = dataset[0:train_size,:], dataset[train_size:len(dataset),:]

    #create
    trainX = create_dataset(train)

I think the following line is wrong:

我认为以下行是错误的:

temps = DataFrame(datasets.values)

My zahlenreihe.csv just has integers ordered like:

我的 zahlenreihe.csv 只有整数排序如下:

  1
  2
  3
  4
  5
  n

How should i handle it?

我该如何处理?

回答by T.Setso

The solution: the given dataset was already an array, so I didnt need to call .value.

解决方案:给定的数据集已经是一个数组,所以我不需要调用.value。
