![]() ![]() VS Code is openly extensible and many extensions are available. VS Code is free for both private and commercial use, runs on Windows, macOS and Linux, and includes support for linting, debugging, task running, version control and Git integration, IntelliSense code completion and conda environments. You can tell VS Code what is your Python path in the settings.Īnd finally you may want to read this (quoted form ): What you can do is updating your VS Code when new versions are released (see )Īlso, VS Code is a code editor and one might use it with Python installed from for instance or Anaconda distribution. Anaconda add some extensions by default to VS Code, but you can always install them yourself. It does not matter if you install them separately or first install Anaconda and install VS Code from there. Or if (num1 STL library.As far as I know, VS Code is an independent (in terms of your question!) software which is just shipped with Anaconda. Hence, expressions of the type: if (num1=num2). If two doubles differ by less than numeric_limits::epsilon(), they are seen as the same number for the machine. The issue would show up when I was dealing with numbers that were slightly different, but numerically indistinguishable for the machine. However, I had a similar problem with a program doing lots of floating-point arithmetics (double precision numbers). Well, it is difficult to say without knowing a bit more about your code. That way, you can make sure you're properly initializing it yourself before using it, otherwise your results will be (hopefully) crazy every time you run it - even in debug mode with the debug heap! One great debugging tip that helped out: write a custom malloc that immediately fills memory with completely random data. Chaos theory in action! Thanks for the guidance. Unfortunately, the adjustment was so subtle as to almost be unnoticeable, and the memory in question was properly reset after the first "frame" of processing, but the initial conditions were already slightly different and the damage had been done. when run from the command line or with Ctrl-F5) the values were more random and would sometimes cause tiny deviations in the behaviour of the program. The debug heap would (I assume) fill the array with some repeatable value, whereas when the debugger wasn't attached (i.e. They had allocated memory with a malloc and had not initialized the memory to 0. The problem was that deep in the bowels of our code, somebody was accessing parts of a large array before they were initialized. ![]() SOLUTION: As pointed out in the accepted answer, the debug heap was the issue. Does this point to a likely culprit? What are the differences between running an executable with debugging and without? I know that the working directory can possibly be different, but I'm manually adjusting that to make sure that the working directory is identical.īased on these results, it looks like running "with Debugging" (even in a Release build) somehow fixes the problem. Run from Visual Studio without Debugging (Ctrl-F5): Non-repeatable output.Run from Visual Studio with Debugging (F5): Repeatable output.Run directly from command prompt (cmd): Non-repeatable output.Here are the environments and the outcomes: I'm sure the actual executable is the same - they're both release builds and are running the same. ![]() It's a single-threaded application, so there shouldn't be any strange behaviour there in terms of timing.Ĭan somebody enumerate what possible differences could be between the two environments? I'm trying to debug an issue in which an executable produces repeatable output (which I want) when executed directly from Visual Studio, but does not produce repeatable output when executed from the command prompt. ![]()
