TypeError: mean() received an invalid combination of arguments – got (list, dim=int), but expected o

TypeError: mean() received an invalid combination of arguments – got (list, dim=int), but expected one of:

如果是在gpu上,由于在gpu中不能转换为array
A = torch.tensor( [item.cpu().detach().numpy() for item in A] )
1
如果是在cpu上:
A = torch.tensor([item.detach().numpy() for item in A])
1
特别需要提的一点是
如果A是多层嵌套的tensor,比如

A = [
[tensor, tensor].

[tensor, tensor],
]
1
2
3
4
那么还是需要具体把每一个tensor都转化为array才可以,否则数据类型会显示为np._object,而非可以转化为tensor的int,float等数据类型。
