only batches of spatial targets supported (3D tensors) but got targets of dimension

问题产生的原因是使用nn.CrossEntropyLoss()来计算损失的时候,target的维度超过4importtorchimporttorch.nnasnnlogit=torch.ones(size=(4,32,256,256))#b,c,h,wtarget=torch.ones(size=(4,1,256,256))criterion=nn.CrossEntropyLoss()loss=criterion(logit,target)如实target中的C不是1,则可以:importtorchimporttorch.nnasnnlogit=torch.ones(size=(4,32,25

go - embedded 和 field 的区别

有嵌入结构Struct1和定义为字段的结构Struct2。fmt.Printf()的结果相同,只是初始化不同。我对此感到困惑。对不起。Struct1和Struct2之间有什么区别?在什么情况下应该使用哪个?脚本typesample1struct{Datastring}typesample2struct{Datastring}typeStruct1struct{*sample1*sample2}typeStruct2struct{Sample1sample1Sample2sample2}funcmain(){s1:=&Struct1{&sample1{},&sample2{},}s1.s

firebase - Firestore : how to make query where field is null

在我的收藏中,我有几个“token”字段为空的文档。查询:=client.Collection("records").Where("token","==",nil)在Go中,上面的查询返回零个文档。获取“token”字段为空或缺失的所有文档的正确查询是什么? 最佳答案 目前是Go客户端中的一个错误。跟踪https://github.com/GoogleCloudPlatform/google-cloud-go/issues/922. 关于firebase-Firestore:howtom
