I want to loop through each of them and stop as soon as one of them returns the desired result. If the first one works, thats fine. If it has an exception or data is not valid, I would like to move to the next one and so on. How may I achieve this? I have the below code: handleData: function(address) { var self = this; return new Promise(function (resolve, reject) { for (var i = 0; i < self.listAllAvailableProviders.length; ++i) { var handler = self.listAllAvailableProviders[i];

Most programming languages allow characters to be simply indexed by their integer position in the string, making targeting a character or a range a matter of simple maths. Because Swift allows a wide range of characters to be used with various bit depths, a precise (memory?) index for each character has to be found first, based its position from the start or end of the string. These positions can then be passed into a method of the String class that returns the

I freely admit I don't quite understand what would be required to make this work. Any suggestions on how this could be accomplished would be appreciated. I'm using Delphi 7. All of the Widgets are just HTML Code, which when I cut & paste them to my Blogger page for instance, show up and work fine. I'm not sure how to take that same html code and use it in a Delphi form to get similar results. Detailed instructions would be

When I comment out that line, the program compiles. 回答1: What is wrong is that any printf function expects a const char * while you are providing just a char * . Since the buffer can contain whatever you want the compiler is not sure that it will contain a correct format string. Just do fprintf(stderr,"%s

One of the algorithms I'm using is the Gaussian Naive Bayes implementation. One of the attributes of the GaussianNB() function is the following: class_prior_ : array, shape (n_classes,) I want to alter the class prior manually since the data I use is very skewed and the recall of one of the classes is very important. By assigning a high prior probability to that class the recall should increase. However, I can't figure out how to set the attribute
