๐ Hello @zhoujiawei3, thank you for your interest in YOLOv3 ๐! Please visit our โญ๏ธ Tutorials to get started, where you can find quickstart guides for simple tasks like Custom Data Training all the way to advanced concepts like Hyperparameter Evolution.
If this is a ๐ Bug Report, please provide a minimum reproducible example to help us debug it.
If this is a custom training โ Question, please provide as much information as possible, including dataset image examples and training logs, and verify you are following our Tips for Best Training Results.
Requirements
Python>=3.7.0 with all requirements.txt installed including PyTorch>=1.7. To get started:
git clone https://github.com/ultralytics/yolov3 # clone
cd yolov3
pip install -r requirements.txt # install
Environments
YOLOv3 may be run in any of the following up-to-date verified environments (with all dependencies including CUDA/CUDNN, Python and PyTorch preinstalled):
- 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 YOLOv3 GitHub Actions Continuous Integration (CI) tests are currently passing. CI tests verify correct operation of YOLOv3 training, validation, inference, export and benchmarks on macOS, Windows, and Ubuntu every 24 hours and on every commit.
Introducing YOLOv8 ๐
We're excited to announce the launch of our latest state-of-the-art (SOTA) object detection model for 2023 - YOLOv8 ๐!
Designed to be fast, accurate, and easy to use, YOLOv8 is an ideal choice for a wide range of object detection, image segmentation and image classification tasks. With YOLOv8, you'll be able to quickly and accurately detect objects in real-time, streamline your workflows, and achieve new levels of accuracy in your projects.
Check out our YOLOv8 Docs for details and get started with:
pip install ultralytics
from yolov3.
@zhoujiawei3 this issue may occur if you are using a newer version of YOLOv3 (v9.6.0
), but your model weights file (yolov3.pt
) is from an older version. The no anchor_grid
error suggests that the model structure has changed between the versions.
To resolve this issue, you can try one of the following:
-
Use the compatible version of the model weights file (
yolov3.pt
) that matches your YOLOv3 version (v9.6.0
in this case). Make sure the model weights file is from the same release or commit as the version you are currently using. -
Train the model using the new version (
v9.6.0
) with your own dataset. This ensures that the model weights and structure are consistent.
If you have any further questions or need assistance, please don't hesitate to ask. The YOLO community and the Ultralytics team are here to help!

ckpt = torch.load(weights, map_location=device) # load checkpoint
model = Model(opt.cfg or ckpt['model'].yaml, ch=3, nc=nc, anchors=hyp.get('anchors')).to(device) # create
exclude = ['anchor'] if (opt.cfg or hyp.get('anchors')) and not resume else [] # exclude keys
csd = ckpt['model'].float().state_dict() # checkpoint state_dict as FP32
csd = intersect_dicts(csd, model.state_dict(), exclude=exclude) # intersect
model.load_state_dict(csd, strict=False) # load
logger.info(f'Transferred {len(csd)}/{len(model.state_dict())} items from {weights}') # report
The code to load checkpoint is from Yolov3.9.6๏ผmy opt.cfg is empty
still 439/440
from yolov3.
Hi there! It seems that when loading the checkpoint using YOLOv3 version 9.6, the model is still showing 439 out of 440 items. This could be due to the mismatch between the checkpoint and the model state, possibly caused by differences in the model architecture or configurations.
To troubleshoot this, you can ensure that the checkpoint matches the exact architecture and configurations of the model, or you may need to adjust the loading process to handle any discrepancies between the checkpoint and the model state.
