How to avoid "CUDA out of memory" in PyTorch. Send the batches to CUDA iteratively, and make small batch sizes. Don't send all your data to CUDA at once in the beginning. Rather, do it as follows: You can also use dtypes that use less memory. For instance, torch.float16 or torch.half.
16.08.2020 · The same Windows 10 + CUDA 10.1 + CUDNN 7.6.5.32 + Nvidia Driver 418.96 (comes along with CUDA 10.1) are both on laptop and on PC. The fact that training with TensorFlow 2.3 runs smoothly on the GPU on my PC, yet it fails allocating memory for training only with PyTorch.
2) Use this code to clear your memory: import torch torch.cuda.empty_cache () 3) You can also use this code to clear your memory : from numba import cuda cuda.select_device (0) cuda.close () cuda.select_device (0) 4) Here is the full code for releasing CUDA memory:
Specify the GPU to use. device = torch.device("cuda" if torch.cuda.is_available() and not args.no_cuda else "cpu") # cuda Specifies the GPU device to be used model = torch.nn.DataParallel(model, device_ids= [0, 1, 3]) # Specify the device number to be used for multi-GPU parallel processing. So you can run happily.

Feb 23, 2019 · Did you specify any devices using CUDA_VISIBLE_DEVICES? I am just specifying the device via: device = torch.device('cuda:4') I am still pretty green here so I am not really sure what the difference is, however, this is the first time I have run into a situation of running out of memory on one of these particular models.

03.11.2017 · @SsnL, @apaszke. It looks like in the context-manager in torch/cuda/__init__.py, the prev_idx gets reset in __enter__ to the default device index (which is the first visible GPU), and then it gets set to that upon __exit__ instead of to -1. So the context first gets created on the specified GPU (i.e. GPU5), then some more context gets created on GPU0, and then all the …
