Comments
👋 Hello @pubpy2015, thank you for your interest in YOLOv5 🚀! Please visit our ⭐️ 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 🐛 Bug Report, please provide screenshots and minimum viable code to reproduce your issue, otherwise we can not help you. If this is a custom training ❓ Question, please provide as much information as possible, including dataset images, training logs, screenshots, and a public link to online W&B logging if available. For business inquiries or professional support requests please visit https://ultralytics.com or email [email protected]. RequirementsPython>=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 EnvironmentsYOLOv5 may be run in any of the following up-to-date verified environments (with all dependencies including CUDA/CUDNN, Python and PyTorch preinstalled):
StatusIf 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. |
@pubpy2015 👋 hi, thanks for letting us know about this possible problem with YOLOv5 🚀. We've created a few short guidelines below to help users provide what we need in order to start investigating a possible problem. How to create a Minimal, Reproducible ExampleWhen asking a question, people will be better able to provide help if you provide code that they can easily understand and use to reproduce the problem. This is referred to by community members as creating a minimum reproducible example. Your code that reproduces the problem should be:
For Ultralytics to provide assistance your code should also be:
If you believe your problem meets all the above criteria, please close this issue and raise a new one using the 🐛 Bug Report template with a minimum reproducible example to help us better understand and diagnose your problem. Thank you! 😃 |
Thanks for reply! This is not problem, just is a question about multi stage detection or how to using multi thread with yolov5 ? |
@pubpy2015 I think you should be able to load multiple models for threaded inference with PyTorch Hub. YOLOv5 🚀 PyTorch Hub models allow for simple model loading and inference in a pure python environment without using Simple Inference ExampleThis example loads a pretrained YOLOv5s model from PyTorch Hub as import torch
# Model
model = torch.hub.load('ultralytics/yolov5', 'yolov5s') # yolov5n - yolov5x6 official model
# 'custom', 'path/to/best.pt') # custom model
# Images
im = 'https://ultralytics.com/images/zidane.jpg' # or file, Path, URL, PIL, OpenCV, numpy, list
# Inference
results = model(im)
# Results
results.print() # or .show(), .save(), .crop(), .pandas(), etc.
results.xyxy[0] # im predictions (tensor)
results.pandas().xyxy[0] # im predictions (pandas)
# xmin ymin xmax ymax confidence class name
# 0 749.50 43.50 1148.0 704.5 0.874023 0 person

results.pandas().xyxy[0].value_counts('name') # class counts (pandas)

@pubpy2015 can you please share the dataset details here , that will help me to fastest the process. thanking you in advance. |
Hello @devendraswamy! We would love to help you with your dataset and training process, but we need more information. Could you please provide more details about your dataset, such as the format and contents of your images and labels, and the size of the dataset? Once we have a clearer picture, we can suggest some ways to streamline your training process. Thank you! |
Hey @pubpy2015 I have a similar situation as you've heard before! Have you figured out a way to approach this? Thanks :) |

Question
Hi,
I have a vehicle detection model and vehicle color detection model.
First stage, detect vehicle on image
Second stage: detect vehicle color on vehicle image, which cropped from original image.
It works fine but if on original image has many vehicle, the detection time of second state will increase according to number of vehicle on original image.
I am trying using thread for second stage, using 1 thread per vehicle, it can run but detection time of each thread bigger many time.
Please advice in this case.
