While PyTorch aggressively frees up memory, a pytorch process may not give back the memory back to the OS even after you del your tensors. This memory is cached so that it can be quickly allocated to new tensors being allocated without requesting the OS new extra memory.

Try delete the object with del and then apply torch.cuda.empty_cache (). The reusable memory will be freed after this operation. Share. Improve this answer. Follow this answer to receive notifications. answered May 6 '19 at 4:32. HzCheng. HzCheng.

18.04.2017 · That’s right. When there are multiple processes on one GPU that each use a PyTorch-style caching allocator there are corner cases where you can hit OOMs, but it’s very unlikely if all processes are allocating memory frequently (it happens when one proc’s cache is sitting on a bunch of unused memory and another is trying to malloc but doesn’t have anything …

Sep 09, 2019 · I am training PyTorch deep learning models on a Jupyter-Lab notebook, using CUDA on a Tesla K80 GPU to train. While doing training iterations, the 12 GB of GPU memory are used. I finish training by saving the model checkpoint, but want to continue using the notebook for further analysis (analyze intermediate results, etc.).

Apr 08, 2018 · Clearing GPU Memory - PyTorch. I am trying to run the first lesson locally on a machine with GeForce GTX 760 which has 2GB of memory. After executing this block of code: arch = resnet34 data = ImageClassifierData.from_paths (PATH, tfms=tfms_from_model (arch, sz)) learn = ConvLearner.pretrained (arch, data, precompute=True) learn.fit (0.01, 2) The GPU memory jumped from 350MB to 700MB, going on with the tutorial and executing more blocks of code which had a training operation in them caused ...

05.01.2021 · I’ve seen several threads (here and elsewhere) discussing similar memory issues on GPUs, but none when running PyTorch on CPUs (no CUDA), so hopefully this isn’t too repetitive. In a nutshell, I want to train several different models in order to compare their performance, but I cannot run more than 2-3 on my machine without the kernel crashing for lack of RAM (top …
