debug

1、报错信息：

normal() received an invalid combination of arguments - got (int, float, reguires_grad=bool, size=tuple), but expected one of:
 * (Tensor mean, Tensor std, *, torch.Generator generator, Tensor out)
 * (Tensor mean, float std, *, torch.Generator generator, Tensor out)
 * (float mean, Tensor std, *, torch.Generator generator, Tensor out)
 * (float mean, float std, tuple of ints size, *, torch.Generator generator, Tensor out, torch.dtype dtype, torch.layout layout, torch.device device, bool pin_memory, bool requires_grad)
1.1、所处情况

num_inputs = 784   # 28*28=784
num_outputs = 10
# 初始化权重和偏置
w = torch.normal(0,0.01, size=(num_inputs,num_outputs),reguires_grad=True)    
b = torch.zeros(num_outputs, require_grad=True)

在第四行报错。

1.2、解决方式

重启服务，重新运行一次又好了，我真醉了。。。
