Question

How long will yolov5s take for an epoch on coco 2017 dataset ?

Additional

I use 4 GPU (3090 24GB) and DDP mode to train my yolov5s on COCO2017 dataset. But it takes about 24 hours for an epoch. On yolov5 Readme.md file, it is said that 'Training times for YOLOv5n/s/m/l/x are 1/2/4/6/8 days on a V100 GPU'. My training time is too long. Is there something wrong with me ?

Requirements

Python>=3.7.0 with all requirements.txt installed including PyTorch>=1.7. To get started:

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

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.

Maybe I have changed the source code too much. When I use the unchanged source code, it takes about 20 min / epoch on 4 NVIDIA 3090

@Guo-Stone yes seems correct for master code.
