CUDA is out of memory runtime error

[sonyta29]

❔Question

I'm trying to evaluate the performance of yolov5s trained on costum dataset using val.py but i'm getting this error : CUDA out of memory ( when evaluating the yolov5s trained on the coco dataset i'm not getting this error) I tried this solution https://stackoverflow.com/questions/59129812/how-to-avoid-cuda-out-of-memory-in-pytorch but it didn't work

I'll be grateful for anyone who can help or suggests a working solution for this issue

Requirements

Python>=3.6.0 with all requirements.txt installed including PyTorch>=1.7. To get started:

$ git clone https://github.com/ultralytics/yolov5
$ cd yolov5
$ pip install -r requirements.txt

Environments

YOLOv5 may be run in any of the following up-to-date verified environments (with all dependencies including CUDA/CUDNN, Python and PyTorch preinstalled):

• Google Colab and Kaggle notebooks with free GPU:
• Google Cloud Deep Learning VM. See GCP Quickstart Guide
• Amazon Deep Learning AMI. See AWS Quickstart Guide
• Docker Image. See Docker Quickstart Guide

Status

If this badge is green, all YOLOv5 GitHub Actions Continuous Integration (CI) tests are currently passing. CI tests verify correct operation of YOLOv5 training (train.py), validation (val.py), inference (detect.py) and export (export.py) on MacOS, Windows, and Ubuntu every 24 hours and on every commit.

@sonyta29 👋 Hello! Thanks for asking about CUDA memory issues. YOLOv5 🚀 can be trained on CPU, single-GPU, or multi-GPU. When training on GPU it is important to keep your batch-size small enough that you do not use all of your GPU memory, otherwise you will see a CUDA Out Of Memory (OOM) Error and your training will crash. You can observe your CUDA memory utilization using either the nvidia-smi command or by viewing your console output:

If you encounter a CUDA OOM error, the steps you can take to reduce your memory usage are:

• Reduce --batch-size
• Reduce --img-size
• Reduce model size, i.e. from YOLOv5x -> YOLOv5l -> YOLOv5m -> YOLOv5s
• Train with multi-GPU at the same --batch-size
• Upgrade your hardware to a larger GPU
• Train on free GPU backends with up to 16GB of CUDA memory:

@glenn-jocher Thank you for replying and explaining this issue... I already trained the yolov5s on Google Colab and then i have just downloaded the trained weights... by running the val.py with -- weights (my_custom_weights).pt make this problem.

I'm going to follow the reducing memory usage steps that you've mentioned. Thank you !
