Nov 28, 2021 · Pytorch 1.10, CUDA 11.3 Python 3.7.9 Contributor sveneschlbeck commented on Nov 28, 2021 @craftpag This is not a parameter to be found in the code here but a PyTorch command that (if I'm not wrong) needs to be set as an environment variable. Try setting PYTORCH_CUDA_ALLOC_CONF=max_split_size_mb:<cache in mb here>.

28.12.2021 · CUDA out of memory 解决办法 当使用 Pytorch GPU进行计算时经常遇到GPU存储空间过满，原因大致有两点： 1.Batch_size设置过大，超过显存空间 解决办法： 减小Batch_size 2.之前程序运行结束后未释放显存 解决办法： 按住键盘上的Win+R在弹出的框里输入cmd，进入控制台, 然后 ...

CUDA semantics. torch.cuda is used to set up and run CUDA operations. It keeps track of the currently selected GPU, and all CUDA tensors you allocate will by default be created on that device. The selected device can be changed with a torch.cuda.device context manager.

25.11.2021 · I almost always run out of memory in the first pass of my training loop. From the looks of it Pytorch allocates as much memory as possible for the model. I’ve tried torch.cuda.set_per_process_memory_fraction() and have found that the model can be fit into 7gb or 13gb of GPU memory, but in both cases it doesn’t leave enough room for batches and/or …

TensorFloat-32(TF32) on Ampere devices¶. Starting in PyTorch 1.7, there is a new flag called allow_tf32 which defaults to true. This flag controls whether PyTorch is allowed to use the TensorFloat32 (TF32) tensor cores, available on new NVIDIA GPUs since Ampere, internally to compute matmul (matrix multiplies and batched matrix multiplies) and convolutions.
