Installing RIf you don't have R on your system, installing R (and uninstalling) is very easy. Do an Internet search for "Install R" and you'll find a page on the cran.r-project.org Web site with a link labeled "Download R 3.x.y for Windows." Click that link and you'll get an option to run a self-extracting installer file named something like R-3.x.y-win.exe. Click on the Run button presented to you by your browser to launch the installer. You can accept all the configuration defaults and installation is very quick. The demo program (technically a script because R is interpreted) uses R version 3.4.2, but any 3.x version will work.

matplotlib,pyplot.imshow expects a numpy array in a valid image shape (e.g. [height, width, channels] or [height, width]), while you are passing tensors in the shape [batch_size, channels, height, width] to it.You would thus have to index each image (via image = images[0]) and permute the axes to match the expected shape:

SAMPLE RANDOM PERMUTATION Name: SAMPLE RANDOM PERMUTATION (LET) Type: Let Subcommand Purpose: Generate a series of random permutations where possibly only a subset of the random permutations will be retained and where a specified proportion of the permutation values are allowed. Description: For a given size N, to generate a random permutation the integers from 1 to N are randomly sampled (without replacement) until all elements have been selected. This is implemented with the command LET Y = RANDOM PERMUTATION FOR I = 1 1 N This SAMPLE RANDOM PERMUTATION command was motivated by the desire to simulate the following problem. Given a worm that has infected a single computer, simulate the following: The infected machine will propogate to NKEEP IP addresses from a master list of NPOP IP addresses. Of the NPOP addresses, only a proportion, p, denote addresses corresponding to an actual machine. That is, there will be p*NPOP valid addresses. Each newly infected machine will likewise attempt to propogate to NKEEP addresses. This process will be repated until all IP addresses corresponding to valid machines are infected. The Program 1 example demonstrates how this simulation can be implemented using the SAMPLE RANDOM PERMUTATION command. Syntax: LET = SAMPLE RANDOM PERMUTATION where is a number or parameter that specifies the size of the random permutation; is a number of parameter that specifies how many permutated values are kept at each step; is a parameter or number (greater than 0 and less than or equal to 1) that specifies the proportion of valid permutation values; is a number of parameter (less than or equal to ) that specifies how many sets of randon permutations are generated; is a variable where the permutated values are saved; is a variable that identifies which iteration generated the permuted values. Examples: LET Y TAG = SAMPLE RANDOM PERMUTATION NPOP NKEEP P NITER Note: The SEED command can be used to specify a seed for the random number generation. The SET RANDOM NUMBER GENERATOR command can be used to specify which random number generator to use. Note: By default, only the unique permutation values in the output variable are saved. If you want all permutation values to be saved, then enter the command SET SAMPLE RANDOM PERMUTATION DISTINCT OFF This is demonstrated in the Program 2 and Program 3 examples below. Note: Although this command was implemented with a specific simulation scenario in mind, it does have wider applicability. Specifically, it can be used to efficiently implement two sample permutation tests. The Program 2 and Program 3 examples below demonstrate a two sample permutation test for the difference between the means of two samples. These examples can be easily adapted to test for the difference between other location statistics such as the median or the trimmed mean. Based on extensive simulation studies, Higgins recommends that 1,600 random permutations should be sufficient for most purposes. Note: This routine uses a random permutation algorithm suggested by Knuth. Specifically, it adapts the RANDPERM routine of Knoble. Default: None Synonyms: None Related Commands: LET = Generate data transformations. RANDOM PERMUTATION = Generate a random permutation. SEED = Specify the seed for random number generation. RANDOM NUMBER GENERATOR = Specify the random number generator to use. RANDOM NUMBER = Generate random numbers from a specified distribution. BOOTSTRAP SAMPLE = Generate a bootstrap sample.

When cufftXtMemcpy() is used to copy data from GPU memory back to host memory, the results are in natural order regardless of whether the data on the GPUs is in natural order or permuted. Using CUFFT_COPY_DEVICE_TO_DEVICE allows users to copy data from the permuted data format produced after a single transform to the natural order on GPUs.

For single 2D or 3D transforms on multiple GPUs, when cufftXtMemcpy() distributes the data to the GPUs, the array is divided on the X axis. E.G. for two GPUs half of the X dimenson points, for all Y (and Z) values, are copied to each of the GPUs. When the transform is computed, the data are permuted such that they are divided on the Y axis. I.E. half of the Y dimension points, for all X (and Z) values are on each of the GPUs. 2b1af7f3a8
