问题 First off, I have read many posts and articles about out of memory exceptions but none of them have helped with my situation. What I'm trying to do is load an image from the sd card but scale it to an exact pixel size. I first get the width and height of the image and calculate the sample size: final BitmapFactory.Options options = new BitmapFactory.Options(); options.inJustDecodeBounds = true; BitmapFactory.decodeFile(backgroundPath, options); // Calculate inSampleSize options.inSampleSize =

Out of memory when using `outer` in solving my big normal equation for least squares estimation

问题 Consider the following example in R: x1 <- rnorm(100000) x2 <- rnorm(100000) g <- cbind(x1, x2, x1^2, x2^2) gg <- t(g) %*% g gginv <- solve(gg) bigmatrix <- outer(x1, x2, "<=") Gw <- t(g) %*% bigmatrix beta <- gginv %*% Gw w1 <- bigmatrix - g %*% beta If I try to run such a thing in my computer, it will throw a memory error (because the bigmatrix is too big). Do you know how can I achieve the same, without running into this problem? 回答1: This is a least squares problem with 100,000 responses.

问题 This question already has answers here : Opening A large JSON file in Python (3 answers) Closed 10 months ago . I have a very large JSON (11 gb) file that is too large to read into my memory. I would like to break it up into smaller files to analyze the data. I am currently using Python and Pandas for the analysis and I am wondering if there is some way to access chunks of the file so that it can be read into memory without crashing the program. Ideally, I would like to break the years worth

How to detect out-of-memory segfaults?

问题 How does one detect whether a segfault is being caused by an out-of-memory condition? I have a segfault that defies diagnosis by valgrind and duma/efence because it seems to crash those tools themselves (Valgrind "the impossibe happened", duma: "mprotect() failed: Cannot allocate memory" ) The application (Gazebo) simply crashes with a segfault, and a stack trace that doesn't seem to offer many hints as to why. TLDR: Is there an easy tool or method to either confirm or rule out the out-of

问题 In a memory hungry app I'm developing I'm facing OutOfMemoryExceptions. I expected to never have this kind of exceptions with virtual memory. Why if it is needed more RAM than available the OS is not using the HD as RAM? 回答1: You can get an OutOfMemoryException in many different ways. In 32-bit windows, a process can use 2GB of virtual address space (I believe it's 1TB in 64-bit applications). Keep in mind this is not RAM, it is completely different, hence "virtual". So forget about RAM. All

问题 I have a function which resizes a bitmap. It's such a "bread and butter" operation that I simply copied it from another project: private Bitmap ResizeBitmap(Bitmap orig) { Bitmap resized = new Bitmap(this.Xsize, this.Ysize, PixelFormat.Format16bppGrayScale); resized.SetResolution(orig.HorizontalResolution, orig.VerticalResolution); using (Graphics g = Graphics.FromImage(resized)) { g.DrawImage(orig, 0, 0, resized.Width, resized.Height); } return resized; } However, I kept getting OutOfMemory
