I'm trying to run a reinforcement learning algorithm using pytorch, but it keeps telling me that CUDA is out of memory. However, it seems that pytorch is only accessing a tiny amount of my GPU's memory.
RuntimeError: CUDA out of memory. Tried to allocate 2.00 MiB (GPU 0; 4.00 GiB total capacity; 3.78 MiB already allocated; 0 bytes free; 4.00 MiB reserved in total by PyTorch)
It's not that PyTorch is only accessing a tiny amount of GPU memory, but your PyTorch program accumulatively allocated tensors to the GPU memory, and that 2 MB tensor hits the limitation. Try to use a lower batch size or run the model with half-precision to save the GPU memory.
This command should work for PyTorch to access the GPU memory.

I am trying to enhance an audio file (3:16 minutes in length, available here) using Speechbrain. If I run the code below (from this tutorial), I get the error OutOfMemoryError: CUDA out of memory. Tried to allocate 2.00 MiB (GPU 0; 39.59 GiB total capacity; 33.60 GiB already allocated; 3.19 MiB free; 38.06 GiB reserved in total by PyTorch) If reserved memory is >> allocated memory try setting max_split_size_mb to avoid fragmentation. See documentation for Memory Management and PYTORCH_CUDA_ALLOC_CONF.
What is the recommended way to fix the issue? Should I just cut the audio file in pieces?
from speechbrain.pretrained import SepformerSeparation as separator
import torchaudio
model = separator.from_hparams(source="speechbrain/sepformer-wham-enhancement",
savedir='pretrained_models/sepformer-wham-enhancement', run_opts={"device":"cuda"})
est_sources = model.separate_file(path=audio_file)
torchaudio.save("enhanced_wham.wav", est_sources[:, :, 0].detach().cpu(), 8000)
I'm Trying to build a parser to recognize entities from text given and to train the spacy model with GPU I went ahead and installed all the necessary packages but while training it runs the first iteration and throws the "Cuda Out Of Memory Error"
i was using this command on my terminal to train the model: python -m spacy train C:\Users\User\PycharmProjects\pythonProject\pythonProject3\config.cfg --output ./output --paths.train ./train_data.spacy --paths.dev ./test_data.spacy --gpu-id 0
And after the First Iteration it gives me this error:
RuntimeError: CUDA out of memory. Tried to allocate 12.00 MiB (GPU 0; 6.00 GiB total capacity; 4.99 GiB already allocated; 0 bytes free; 5.33 GiB reserved in total by PyTorch) If reserved memory is >> allocated memory try setting max_split_size_mb to avoid fragmentation. See documentation for Memory Management and PYTORCH_CUDA_ALLOC_CONF
What i dont seem to understand here is it mentions 0 bytes free. is there anything i can possibly do to provide some space and train my Model?
I tried almost all the option to train the model including reducing batch size to 1 and some other steps as described here
How do I select which GPU to run a job on?,
But still i get the error
RuntimeError: CUDA out of memory. Tried to allocate 238.00 MiB (GPU 3; 15.90 GiB total capacity; 15.20 GiB already allocated; 1.88 MiB free; 9.25 MiB cached)
This is the notebook , configured in Azure ML workspace with N24-GPU
thank you
Check your memory usage before you start training, sometimes detectron2 doesn't free vram after use, particularly if training crashes. If this is the case, the easiest way to fix the issue in the short term is a reboot.
As for a long term fix to this issue, I cant give any advise other than ensuring your using the latest version of everything.
I'm trying to train a custom NER model on top of Spacy transformer model.
For faster training, I'm running it on a GPU with cuda on Google Colab Pro with High-Ram server.
After the first iteration, I get an error:
RuntimeError: CUDA out of memory. Tried to allocate 480.00 MiB (GPU 0;
11.17 GiB total capacity; 9.32 GiB already allocated; 193.31 MiB free; 10.32 GiB reserved in total by PyTorch)
For the above error I tried emptying cache too. But still I'm getting this error. Seems like it’s not freeing up enough space.
import torch
torch.cuda.empty_cache()
Moreover I also tried reducing the batch sizes even to 2. Still the same error occurs.
I was processing a large dataset and ran into this error: "RuntimeError: CUDA out of memory. Tried to allocate 1.35 GiB (GPU 0; 8.00 GiB total capacity; 3.45 GiB already allocated; 1.20 GiB free; 4.79 GiB reserved in total by PyTorch).
Any thought on how to solve this?
I met the same problem before. It's not a bug, you just ran out of memory on your GPU.
One way to solve it is to reduce the batch size until your code will run without this error.
if it not works, better to understand your model. A single 8GiB GPU may not handle a large and deep model. You should consider changing a GPU with larger memory and find a lab to help you (Google Colab can help)
if you are just doing evaluate, force a tensor to be run CPU would be fine
Try model compression algorithm
If you are using full batch gradient descent (or similar), use mini batch instead with smaller batch size and reflect the same in dataloaders.
