In C++ code bases which used to be C, one can find the pattern goto cleanup. As the goto command makes the workflow of a function harder to understand, this is often avoided. Often, it can be replaced by return statements, loops, functions. Though, with the goto cleanup one needs to get rid of clean...

A simple OGL 4.0 GLSL shader program that shows how to map a 2D texture on a mesh. The program is executed with a phyton script. To run the script, PyOpenGL and NumPy must be installed. The texture matrix defines how the texture is mapped on the mesh. By manipulating the texture matrix, the textu...

This is an Angular 2 wrapper library for Dropzone. npm install angular2-dropzone-wrapper --save-dev Load the module for your app import { DropzoneModule } from 'angular2-dropzone-wrapper'; import { DropzoneConfigInterface } from 'angular2-dropzone-wrapper'; const DROPZONE_CONFIG: Dropzon...

To ensure that a GPU version TensorFlow process only runs on CPU: import os os.environ["CUDA_VISIBLE_DEVICES"]="-1" import tensorflow as tf For more information on the CUDA_VISIBLE_DEVICES, have a look to this answer or to the CUDA documentation.

import tensorflow as tf sess = tf.Session(config=tf.ConfigProto(device_count={'GPU': 0})) Bear in mind that this method prevents the TensorFlow Graph from using the GPU but TensorFlow still lock the GPU device as described in this an issue opened on this method. Using the CUDA_VISIBLE_DEVICES se...

To use a particular set of GPU devices, the CUDA_VISIBLE_DEVICES environment variable can be used: import os os.environ["CUDA_DEVICE_ORDER"]="PCI_BUS_ID" # see issue #152 os.environ["CUDA_VISIBLE_DEVICES"]="0" # Will use only the first GPU device os.en...

By default, TensorFlow pre-allocate the whole memory of the GPU card (which can causes CUDA_OUT_OF_MEMORY warning). To change this, it is possible to change the percentage of memory pre-allocated, using per_process_gpu_memory_fraction config option, A value between 0 and 1 that indicates wh...

A simple OGL 4.0 GLSL shader program that shows the use of a interface block and a uniform block on a Cook-Torrance microfacet light model implementation. The program is executed with a phyton script. To run the script, PyOpenGL and NumPy must be installed. An Interface Block is a group of GLSL in...

The widget ttk.progress is useful when dealing with long computations so that the user knows that the program is running. Following, an example updating a progressbar each 0.5 seconds is given: Function updating the progressbar def progress(currentValue): progressbar["value"]=curren...
