[报错]ufunc ‘add‘ did not contain a loop with signature matching types (dtype(‘＜U32‘), dtype(‘＜U32‘)) 报错类型： ufunc 'add' did not contain a loop with signature matching types (dtype('<U32'), dtype('<U32')) -> dtype('<U32') 'add’函数是我自定义的加法函数该错误类型翻译后为：ufunc ‘add’ 不包含具有签名匹配类型的循环查看其它人的错误原因，大部分是由于数据类型不匹配的原因如下add 函数，当x为int类型，y为str类型的时候，就会出现此种报错。阅读详情
