RuntimeError: found dtype long but expected float 这样的错误时,这通常表明在你的程序中某处预期接收的是浮点数(float)类型的数据,但实际上接收到的是长整型(long,在Python 3中通常表示为int,因为Python 3中没有单独的long类型)数据。这个问题常见于使用NumPy、PyTorch、TensorFlow等科学计算或机器学习库时。以下...
程序出错,上图,报错内容:RuntimeError: FounddtypeLong but expected Float (PS下背景:在B站上看‘刘二大人’的《《PyTorch深度学习实践》完结合集》,照着上面输入代码,运行了之后,就出问题。) 我看了一下,感觉是我现在的是pytorch 1.8的版本,参数不对,应该是做了一些优化,所以有些东西和老版本的不一样了; ...
说明此时需要float型数据，但识别到long型数据,此时需要对入参和出参做一下类型转换 例证如下：
