12.11.2019 · Currently, I am using PyTorch built with CPU only support. When I run inference, somehow information for that input file is stored in cache and memory keeps on increasing for every new unique file used for inference. On the other hand, memory usage does not increase if i use the same file again and again. Is there a way to clear cache like cuda.empty_cache() in …

AttributeError: module 'torch.cuda' has no attribute 'empty',This issue won't be solved, if you clear the cache repeatedly.

Mar 07, 2018 · 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.
