title: Subprocessing Data Loading in pytroch into Google Colab
body: <p>I'm working on training a deep neural network using <code>pytorch</code> and I use <code>DataLoader</code> for preprocessing data and multi-processing purpose over dataset. I set <code>num_workers</code> attribute to positive number like 4 and my <code>batch_size</code> is 8. I train network on <code>Google Colab</code> Environment but when training keep on after few minutes, stop training and get error in reading <code>.PNG</code> files. I think it's memory error and I want to know what is relation between <strong>number of GPU</strong> and <strong>batch_size</strong> and <strong>num_workers</strong> to set up a reasonable relation between them specially in <strong>Google Colab</strong> . </p>
