[英]AttributeError: 'numpy.ndarray' object has no attribute 'index' in Python
我想创建一个数据帧的索引等于另一个数据帧的索引。
y_test_proba.index = X_test.index
但它有一个错误。
AttributeError: 'numpy.ndarray' object has no attribute 'index'
如何解决这个错误？
将数组强制为 Pandas DataFrame 将使您能够访问索引。
X_test_df = pandas.DataFrame(X_test)
X_test_df.index
