AttributeError: ‘torch.return_types.max‘ object has no attribute ‘shape‘

测试程序有一句出现了bug，以前没见过，就是正常使用，不觉得会有错。

import torchb = torch.range(1,12,1).reshape([3,2,2])
print(b,b.shape)d = torch.max(b,dim=0,keepdim=True)###bug所在print(d,d.shape)

网上查了一下，torch.max（）返回是个turtle，包含了 value，index，所以错误原因也找到了，没有定义index的变量。修改后如下：

import torchb = torch.range(1,12,1).reshape([3,2,2])
print(b,b.shape)d,e = torch.max(b,dim=0,keepdim=True)print(d,d.shape)
print(e)

OK了！！！！
