梯度下降法是最著名的优化算法之一,本文基于Python和Pytorch编写了梯度优化程序Gradient_optim,并将结果与Pytorch中自带的梯度优化器torch.optim对比。 1.程序适用于任意维解析函数的无约束优化问题,求解最小值及最小值点; 2.可实现的梯度法:最陡下降法、共轭梯度法、牛顿法、拟牛顿法等; 3.可选择的一维线搜索法:...
tf.matmul()报错expected scalar type Float but found Double tf.matmul(a,b)将矩阵a乘以矩阵b,生成a * b,这里的a,b要有相同的数据类型,否则会因为数据类型不匹配而出错。 如果出错,请看是前后分别是什么类型的,然后把数据类型进行转换。

🚀 The feature, motivation and pitch Current matmul supports only the same input and output tensor types. As a result it can produce numerically incorrect outputs for cases when input tensors are int8 or float8 (e.g. torch.float8_e5m2): i...
