30.08.2020 · I wanted to free up the CUDA memory and couldn't find a proper way to do that without restarting the kernel. Here I tried these: del model # model is a pl.LightningModule del trainer # pl.Trainer del train_loader # torch DataLoader torch. cuda. empty_cache () # this is also stuck pytorch_lightning. utilities. memory. garbage_collection_cuda ...

05.11.2015 · I think I am catching on. So here is what I see (Windows 7, CUDA 7.5, driver 354.13): Even after cudaFree() has been called on all allocations and cudaDeviceReset() has been called, but while the application is waiting for a key press to terminate, nvidia-smi shows the allocated GPU memory still in use. Only when the app exits after the keypress does nvidia-smi show the …
13.03.2011 · As @ CygnusX1 said, you can't free it. As you have declared it, the memory will be allocated for the life of your program -- NOTE: Even if you never call the kernel. You can however use cudaMalloc, and cudaFree (or new/delete within in …
17.12.2020 · Also, i had the CUDA out of memory. Tried to allocate 18.00 MiB (GPU 0; 11.00 GiB total capacity; 8.63 GiB already allocated; 14.32 MiB free; 97.56 MiB cached) issue. Fixed it to work with Jeremy’s bs (lesson3-camvid/2019) by adding .to_fp16() on the learner. Most probably fragmentation related…
Dec 16, 2020 · In the above example, note that we are dividing the loss by gradient_accumulations for keeping the scale of gradients same as if were training with 64 batch size.For an effective batch size of 64, ideally, we want to average over 64 gradients to apply the updates, so if we don’t divide by gradient_accumulations then we would be applying updates using an average of gradients over the batch ...
07.07.2017 · I have to call this CUDA function from a loop 1000 times and since my 1 iteration is consuming that much of memory, my program just core dumped after 12 Iterations. I am using cudafree for freeing my device memory after each iteration, but I got to know it doesn’t free the memory actually.
09.10.2019 · 🐛 Bug Sometimes, PyTorch does not free memory after a CUDA out of memory exception. To Reproduce Consider the following function: import torch def oom(): try: x = torch.randn(100, 10000, device=1) for i in range(100): l = torch.nn.Linear...
08.07.2018 · I am using a VGG16 pretrained network, and the GPU memory usage (seen via nvidia-smi) increases every mini-batch (even when I delete all variables, or use torch.cuda.empty_cache() in the end of every iteration). It seems…
RuntimeError: CUDA out of memory. Tried to allocate 978.00 MiB (GPU 0; 15.90 GiB total capacity; 14.22 GiB already allocated; 167.88 MiB free; 14.99 GiB reserved in total by PyTorch) I searched for hours trying to find the best way to resolve this.
