假设我们有2个集合:“users”和“posts”，由以下类型建模:typeUserstruct{IDstring`bson:"_id"`Namestring`bson:"name"`Registeredtime.Time`bson:"registered"`}typePoststruct{IDstring`bson:"_id"`UserIDstring`bson:"userID"`Contentstring`bson:"content"`Datetime.Time`bson:"date"`}这些可以在存储/检索单个甚至文档集合时使用，例如:usersColl:=sess.DB("")

ubuntu22.10在安装cuda，使用如下命令：sudoshcuda_11.0.2_450.51.05_linux.run 结果产生错误提示：Failedtoverifygccversion.Seelogat/var/log/cuda-installer.logfordetails.1、这是由于gcc版本不匹配的问题！一般简易解决方法是忽略，使用--override参数sudoshcuda_11.0.2_450.51.05_linux.run--override 2、或者可以变更gcc版本， A、首先在选CUDA版本时，链接尾部可以看到"VersionedOnlineDocumenta
