清空显存可以通过删除所有GPU上的变量来实现。 defclear_memory():cuda.close()cuda.select_device(0)print("GPU memory cleared.") 1. 2. 3. 4. 3. 验证显存是否清空 再次调用check_memory函数,检查显存是否已经被清空。 defverify_memory():check_memory() 1. 2. 完整脚本 将上述函数整合到一个脚本中,...

在PyTorch中,可以使用torch.cuda.set_per_process_memory_fraction()方法来限制每个进程可使用的GPU显存比例。 示例代码: python torch.cuda.set_per_process_memory_fraction(0.5, device=0) 请注意,清理显存的方法可能因框架版本和具体使用情况而有所不同。在实际应用中,建议结合多种方法来优化显存使用,以提高...

It is a GPU memory issue. VRAM rises just importing llama-cpp-python. It is not a lot but in my book that's a no-go already. Then when I load a model with BLAS (cuda) and a few layers and do inference, VRAM goes to 5GB. Fine. Then I delete/unload the model, goes down to...
🐛 Describe the bug I'm looking for a python binding for the host allocator's empty_cache to clear CPU pinned memory. Right now that memory is still held after training finishes, so I'm unable to run any memory intensive post processing. ...
For example, you might have already set up your favorite deep learning framework, such as PyTorch or TensorFlow, including CUDA support, in your global Python environment.Both frameworks are large and can be tricky to set up correctly. You still want to keep your projects in separate ...
