Describe the bug dtrain = xgb.DMatrix(X_train, label=y_train) now requires you to explicitly convert to X_train and y_train dataframes to numpy or you get a type error: ---...

Cannot implicitly convert type 'object' to 'string'. An explicit conversion exists (are you missing a cast?) Cannot implicitly convert type 'System.DBNull' to 'System.DateTime' Cannot implicitly convert type 'void' to 'System.Collections.Generic.List' Cannot insert duplicate key row in object ...
This section describes type casting supported in Java: up casting (widening reference conversion) and down casting (narrowing reference conversion). Cast operation can be written explicitly with the cast operator (T), or implicitly with no operator.
Or the equivalent in Python:network.get_input(0).shape = (4, 3, 224, 224)thanks for the quick reply. I think it is due to lots of constant folding operations in the model, and I used onnx simplifier before the conversion to trt, which significantly increase the model size. I would...
报错内容类似这样的:test.cpp:19:14: error: conversion from 'int' to non-scalar type 'Base' requested,这样就避免了别人隔墙修改你家钱的数量啦。 那么为什么explicit可以起到这个作用呢,在没有声明该关键字之前,编译器根据当前的定义和构造函数,在编译的时候做了一个隐式的类型转换,但是当编译器发现了explic...
Option Explicit is to do with variable declaration and Strict is for type conversions.Option Explicit: When Option Explicit appears in a file, you must explicitly declare all variables using the Dim, Private, Public, or ReDim statements. If you attempt to use an undeclared variable name, an ...
cannot implicitly convert type 'bool?' to 'bool'. An explicit conversion exists (are you missing a cast?) As the others statedbool?is not equal tobool.bool?can also benull, seeNullable<t>(msdn). If you know what thenullstate wants to imply, you easily can use the ?? - null-coales...
