runtime-error

问题 It is the third question i do in stackoverflow about that because every time i got some changes in the way python raise runtime erro. Previous questions were: here and here. In the first question i think was a matter of memory because i anylized many images, in the second case the runtime error happen at this line p2 = numpy.percentile(img, 2) and i think was a numpy module problem. but now i the runtime error happens here: imgbnbin = mh.morph.dilate(gray, disk7) At mahotas function dilate.

问题 I'm learning to use Rootbeer, so I did the following things : [1] Downloaded Rootbeer-1.2.3.jar [2] Installed CUDA Toolkit and CUDA Driver from : http://www.nvidia.com/content/cuda/cuda-downloads.html [3] Compiled the following sample program. [4] Ran ArrayMultApp from NetBeans 8.0.2 import java.util.List; import java.util.ArrayList; import org.trifort.rootbeer.runtime.Kernel; import org.trifort.rootbeer.runtime.Rootbeer; public class ArrayMultApp { public void multArray(int[] array) { List

问题 Does the ferror in this example check check both fprintf s for error, or just the second one? FILE * myout; if ((myout = fopen("Assignment 11.txt", "a")) != NULL) { fprintf(myout, "First print ", str1); fprintf(myout, "Second print", str1); if (ferror(myout)) fprintf(stderr, "Error printing to file!"); fclose(myout); } 回答1: If an error occurs, it won't be reset unless clearerr is called on your stream, so yes, an error occuring on any of both writes is recorded. from ferror manual page: The

问题 I have been given this function to predict the output. It's says refrence error,i am still wondering why? if(function x(){console.log("ABC");}) { x(); } Hope somebody can throw some light on the lexical scope. Thanks in advance. 回答1: What you have there is a function expression , even if a named one, and you're not assigning that expression to anything. The fact that you're naming it x doesn't mean a function x will be hoisted in the scope, because that doesn't work for expressions . function

问题 I tried to compile a simple "hello world" program in C (using MinGW ) from the command prompt and had the following error: R6034 : An application has made an attempt to load the C runtime library incorrectly. Please contact the application's support team for more information. I've done a couple searches on the subject and there seems to be a consensus on stray mscvr files placed in the path variable by other programs. I've downloaded Process Explorer and tried to find any such files, but the

问题 I use ArrayList to store the 'shadows' for every rectangle in the level but when I iterate through the like this: for(int n = 0; n < shadows.size(); ++n){ g2d.fillPolygon(shadows.get(n)[0]); g2d.fillPolygon(shadows.get(n)[1]); g2d.fillPolygon(shadows.get(n)[2]); g2d.fillPolygon(shadows.get(n)[3]); g2d.fillPolygon(shadows.get(n)[4]); g2d.fillPolygon(shadows.get(n)[5]); } I get a java.lang.IndexOutOfBoundsException error that looks like this: Exception in thread "AWT-EventQueue-0" java.lang

问题 Please see this code, where I pass more parameters than expected to a custom function: error_reporting(E_ALL); ini_set("display_errors", 1); daidai("asassa", "asgfasfas", "asassa"); function daidai($aa) { echo $aa; } This doesn't emit an error at all, while I was expecting Warning: function daidai() expects at most 1 parameter, 3 given What puzzles me is that this emits said error as expected: $Odate=new DateTime(); $sfasfasf=$Odate->setTime("23", "59", "30", "unexpected"); Why? 回答1: That is

问题 I'm having a real problem with JavaScript scope in IE 9. This is inside the body of my document (yes, I realize script should go in the head for proper HTML, but I've never had it break a script before). The script is in the body because I don't want to mess with a shared header page for a script that is only relevant for this page: <script type="text/javascript"> function googleMapsQuery(accountNum) { // function code is here (omitted for brevity) } </script> This is inside a td block inside

问题 I have a major problem during loading the extension into the program. I get an exception as there is no valid constructor. The problem is in the line: ekstensja = (ArrayList<Dydaktyk>) ois.readObject(); I get something like that: java.io.InvalidClassException: Dydaktyk; no valid constructor at java.io.ObjectStreamClass$ExceptionInfo.newInvalidClassException(Unknown Source) at java.io.ObjectStreamClass.checkDeserialize(Unknown Source) at java.io.ObjectInputStream.readOrdinaryObject(Unknown
