initialization

问题 When I assess my program, I saw that at some point I get up to 100msec time lapse. I have searched every operation, but individually no operation was taking this time. Then I have noticed that wherever I do place cudaThreadSynchronize call, the first call takes 100 msec. Then I have written such an example below. When cudaThreadSynchronize is called at the first line, the elapsed time value at the end is found less than 1 msec. But if it is not called then it takes 110msec on average. int

问题 Since this is a flutter plugin, I don't want developers depending on the plugin to have to init the plugin in anyway. Maybe they'll have to, but I'd really like for them not to have to. Basically, I want a way of calling the _channel.setMethodCallHandler method automatically when the app depending on the plugin starts. Without other developers having to do so, for instance calling a static method living in the DragndropPlugin class, themselves to "initialize" the plugin. Maybe there are some

问题 Is it possible to set datatables to paginate, but load only the n amount of entries that are displayed from the server? (via Ajax request). In other words, each time you re-sort or click 'Next n entries', a small request is made to the server to load the new entries to display. Thus minimizing the initial load time. Will I be able to do this via the initialization, so that it applies to all datatables in my site? 回答1: Since you're not providing any code I won't be able to do a full answer.

问题 I have a number of related questions about tensorflow behavior when attempting to do graph surgery using import_graph_def . 2 different graph surgeries In the image above, I represent with bold red arrows 2 different graph surgeries. On the left, there are 2 graphs, g1 and g2, and the surgery consists of replacing a node in graph g2 by a node - and everything below it - from graph g1. How to do that is explained in this post. The surgery on the right, which involves replacing nodes that

问题 Why is it possible to use an object initializer to set a private set auto property, when the initializer is called from within the class which owns the auto property? I have included two class as an example. public class MyClass { public string myName { get; private set; } public string myId { get; set; } public static MyClass GetSampleObject() { MyClass mc = new MyClass { myName = "Whatever", // <- works myId = "1234" }; return mc; } } public class MyOtherClass { public static MyClass

问题 Is it valid to copy a struct some of whose members are not initialized? I suspect it is undefined behavior, but if so, it makes leaving any uninitialized members in a struct (even if those members are never used directly) quite dangerous. So I wonder if there is something in the standard that allows it. For instance, is this valid? struct Data { int a, b; }; int main() { Data data; data.a = 5; Data data2 = data; } 回答1: Yes, if the uninitialized member is not an unsigned narrow character type

问题 I get the following base error: 1>c:\program files\microsoft visual studio 10.0\vc\include\utility(163): error C2436: 'second' : member function or nested class in constructor initializer list As well as a lot of sub-errors there - I have no idea at all where to look or what goes wrong. (I know what functions it is about, but I'm staring myself blind on why it doesn't work) The header part: typedef void *DuplicateFn(pTree&, const pTree&); enum DuplicateTy { SKIP, OVERWRITE, ASK }; typedef std
