运行season one中的xgb.py出现问题
这是什么问题呢？？？ Traceback (most recent call last): File "xgb.py", line 58, in dataset3_preds.label = MinMaxScaler().fit_transform(dataset3_preds.label)#区间缩放到[0,1] File "/home/cxy/anaconda3/lib/python3.6/site-packages/sklearn/base.py", line 518, in fit_transform return self.fit(X, **fit_params).transform(X) File "/home/cxy/anaconda3/lib/python3.6/site-packages/sklearn/preprocessing/data.py", line 308, in fit return self.partial_fit(X, y) File "/home/cxy/anaconda3/lib/python3.6/site-packages/sklearn/preprocessing/data.py", line 334, in partial_fit estimator=self, dtype=FLOAT_DTYPES) File "/home/cxy/anaconda3/lib/python3.6/site-packages/sklearn/utils/validation.py", line 410, in check_array "if it contains a single sample.".format(array)) ValueError: Expected 2D array, got 1D array instead: array=[-0.21156955 0.33369869 -0.30134243 ..., 0.08833629 -0.15614033 0.31751922]. Reshape your data either using array.reshape(-1, 1) if your data has a single feature or array.reshape(1, -1) if it contains a single sample.
在MinMaxScaler()那一行上面加一句： dataset3_preds.label=np.array(dataset3_preds.label).reshape(-1,1)
