当你看到错误信息“too many indices for array: array is 2-dimensional, but 3 were indexed”时,这意味着你尝试用三个索引去访问一个二维数组。在NumPy中,数组的维度和索引的数量必须严格匹配。例如,一个二维数组(形状为 (m, n))只能接受两个索引(一个行索引和一个列索引)。如果你尝试使用三个索引,就会...
简介:【Python·问题解决】IndexError: too many indices for array: array is 2-dimensional, but 3 were indexed 前言 今天再训练数据集的时候发现了这样的一个问题,用鸢尾花数据集进行训练跑KPCA的时候可以用,但是到我这故障诊断里就直接报废了,就离谱!!! 遇到的问题 直接给我红色警告!!! 就离谱!!! 当然,...
例如,一维数组表示线性数据,二维数组表示矩阵数据。当你看到“IndexError: too many indices for array: array is 0-dimensional, but 1 were indexed”这个错误时,通常是因为你尝试访问一个0维数组(标量)的元素,但代码中提供的索引数量不正确。这个错误可能出现在使用NumPy库或其他类似库时。例如,如果你有一个0维...
解决过程 conv 参数分别是卷积输入矩阵、卷积核( filter )、输出矩阵(全零矩阵)、步长和偏置项,计算的是卷积输出 调用参数逐个打印结果,发现第二个参数打印的是参数地址,并非打印矩阵,就明白为啥报错了 python3的map返回了迭代器,并非返回列表 加list就完事了...
