阿里云 AI 助理回答 问题描述: 用户在使用Python进行数据处理或调用函数时遇到报错 TypeError: data type not understood,这表明程序在尝试操作或转换数据时,遇到了无法识别的数据类型。 可能原因: 数据类型不匹配:传入函数的参数数据类型与函数期望的数据类型不符。 自定义函数签名错误:自定义函数(如UDF)的返回值类型...
报错TypeError: data type not understood 错误在第三行centrodids = np.zeros(k, n) 原来numpy.zeros的用法用错了 numpy.zeros(shape,dtype = float,order ='C' ) 返回给定形状和类型的新数组,并用零填充。 shape:整数或者整数元组例如:(2,1) dtype:数据类型,可选 order:{‘C’,‘F’}可选,默认C 所...

在写kNN算法想要创建一个全零的二维数组,结果报错TypeError: data type not understood 院代码是np.zeros(row,col) 这是为什么呢? 如何产生一个2×1024的全0矩阵呢?是否是zeros(2,1024) ? 若是上述这种写法就会出现 TypeError: data type not understood 这种错误; 正确的写法是 zeros((2,1024)),python的二维...

The float type is a data type used to store floating-point numbers. The so-called floating-point number can be simply understood as a decimal, and its accuracy can support up to 15-16 significant digits. Python will automatically interpret any number containing a decimal point as a float typ...
