感谢zhaz 的提醒，我把 torch.cuda.empty_cache() 的使用原因更新一下。. 这是原回答： Pytorch 训练时无用的临时变量可能会越来越多，导致 out of memory ，可以使用下面语句来清理这些不需要的变量。. 官网 上的解释为：. Releases all unoccupied cached memory currently held by the caching allocator so that those can be used in other ...
Mar 07, 2018 · Hi, torch.cuda.empty_cache() (EDITED: fixed function name) will release all the GPU memory cache that can be freed. If after calling it, you still have some memory that is used, that means that you have a python variable (either torch Tensor or torch Variable) that reference it, and so it cannot be safely released as you can still access it.
torch.cuda.empty_cache() [source] Releases all unoccupied cached memory currently held by the caching allocator so that those can be used in other GPU application and visible in nvidia-smi. Note empty_cache () doesn’t increase the amount of GPU memory available for PyTorch. However, it may help reduce fragmentation of GPU memory in certain cases.
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:

Share.
20.10.2020 · The command torch.cuda.empty_cache () "releases all unused cached memory from PyTorch so that those can be used by other GPU applications" which is great, but how do you clear the used cache from the GPU? Is the only way to delete the tensors being held in GPU memory one by one? And if so, how do you do that? Thanks!
Sep 09, 2019 · torch.cuda.empty_cache() cleared the most of the used memory but I still have 2.7GB being used. It might be the memory being occupied by the model but I don't know how clear it. I tried model = None and gc.collect() from the other answer and it didn't work. –

Jun 25, 2019 · There is no change in gpu memory after excuting torch.cuda.empty_cache(). I just want to manually delete some unused variables such as grads or other intermediate variables to free up gpu memory. So I tested it by loading the pre-trained weights to gpu, then try to delete it. I’ve tried del, torch.cuda.empty_cache(), but nothing was happening.
