Question

Hi,
I would like to use a custom inference code other than "detect.py". Here is the code I am trying, but not working.

@memelvin99 👋 Hello! Thanks for asking about handling inference results. YOLOv5 🚀 PyTorch Hub models allow for simple model loading and inference in a pure python environment without using detect.py.

Simple Inference Example

This example loads a pretrained YOLOv5s model from PyTorch Hub as model and passes an image for inference. 'yolov5s' is the YOLOv5 'small' model. For details on all available models please see the README. Custom models can also be loaded, including custom trained PyTorch models and their exported variants, i.e. ONNX, TensorRT, TensorFlow, OpenVINO YOLOv5 models.

import torch

# Model
model = torch.hub.load('ultralytics/yolov5', 'yolov5s')  # or yolov5m, yolov5l, yolov5x, etc.
# model = torch.hub.load('ultralytics/yolov5', 'custom', 'path/to/best.pt')  # custom trained 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
# 2  114.75  195.75  1095.0  708.0    0.624512      0  person
# 3  986.00  304.00  1028.0  420.0    0.286865     27     tie

See YOLOv5 PyTorch Hub Tutorial for details.

Good luck 🍀 and let us know if you have any other questions!

[memelvin99]

Thanks for the quick reply.

I have trained a custom model and saved best.pt locally.
I have loaded the model using below code:
"model = torch.hub.load('C:/AI_Projects/fan_engine/yolo', 'custom', path='best.pt', source='local')"
But this code is giving me the error:
"raise URLError('unknown url type: %s' % type)
urllib.error.URLError: "

Here is the complete code:

import torch
path='/content/drive/MyDrive/Volvo/FANCASE/yolo/best.pt') # or yolov5m, yolov5l, yolov5x, custom
model = torch.hub.load('C:/AI_Projects/fan_engine/yolo', 'custom', path='best.pt', source='local')
img = 'C:/AI_Projects/fan_engine/yolo/images/data/11110731_wrong.png'
results = model(img)
results.print()

[glenn-jocher]

@memelvin99 see Colab notebook for example:
https://colab.research.google.com/github/ultralytics/yolov5/blob/master/tutorial.ipynb#scrollTo=GMusP4OAxFu6&line=2&uniqifier=1

[memelvin99]

The above colab sample code is working for me. But the issue is when I am loading my custom model locally. I am getting error:

Exception: Invalid --device 0 request, valid devices are 0 - -1. The cache may be out of date, try force_reload=True

I have also tried model = torch.hub.load('', 'custom', path='best.pt', source='local',force_reload=True)
Still getting the same error.

[mx2013713828]

model = torch.hub.load('../yolov5/','custom',path='Yourpath/best.pt',source='local').
try this.

[glenn-jocher]

@memelvin99 your code is out of date

[tbukfrc]

I'm getting the same error with a similar setup. If the code is out of date, what is the correct way to do this? I'm pulling the line of code from the official tutorials for yolov5.

Edit: for additional clarity, I am running locally on Windows 10, and I am using PyTorch with CUDA. Detect.py works perfectly, but for my use case I am going to need to write my own code, and it keeps failing.

[glenn-jocher]

@Thebombuknow error has been fixed earlier in #6461. To receive this update:

• Git – git pull from within your yolov5/ directory or git clone https://github.com/ultralytics/yolov5 again
• PyTorch Hub – Force-reload model = torch.hub.load('ultralytics/yolov5', 'yolov5s', force_reload=True)
• Notebooks – View updated notebooks
• Docker – sudo docker pull ultralytics/yolov5:latest to update your image

Thank you for spotting this issue and informing us of the problem. Please let us know if this update resolves the issue for you, and feel free to inform us of any other issues you discover or feature requests that come to mind. Happy trainings with YOLOv5 🚀!

[tbukfrc]

Thanks! That fixed it! I just got extremely unlucky, as I happened to pull the repo mere hours before the bug was fixed.

Hi @glenn-jocher,

I have been following your instructions above to get the best results for the custom model.
I followed the instructions and git pulled the clone model again but somehow this option is throwing an error and I am not sure how to interpret the meaning of it to move forward.

Can you help me understand what is happening within the error prompt and how do I proceed to solve this challenge?
THANK YOU LOADS in advance for all of your guidance and efforts.......

WHEN I: try it this way it works:
python3 detect.py --weights /Users/symbadian/Desktop/LIRIS_new_dataset/Old_WorkingYOLOv5/yolov5/runs/train/Pre-Trained-weights/WithAUGS_Better_Perfor/exp_yolov5s/weights/best.pt --source /Users/symbadian/Desktop/LIRIS_new_dataset/Old_WorkingYOLOv5/yolov5/data/images --conf 0.6

BUT I would like to get the results printed

xmin ymin xmax ymax confidence class name

My code:

import torchvision
import torch

# Model
model = torch.hub.load('./new_dataset/yolov5/models/hub/', 'yolov5m6.yaml')

# Images
dir = './new_dataset/yolov5/data/images/'
imgs = [dir + f for f in ('zidane.jpg', 'bus.jpg')]  # batch of images

# Inference
results = model(imgs)
results.print()  # or .show(), .save()

@Symbadian you don't load yamls, you load models, i.e.

model = torch.hub.load('ultralytics/yolov5', 'yolov5s')  # or yolov5m, yolov5l, yolov5x, etc.
model = torch.hub.load('ultralytics/yolov5', 'custom', 'path/to/best.pt')  # custom trained model

[Symbadian]

model = torch.hub.load('ultralytics/yolov5', 'custom', 'path/to/best.pt')

@Symbadian just read your error and fix this yourself. It says unexpected indent. This is user error.

[Symbadian]

model = torch.hub.load('ultralytics/yolov5', 'custom', '/Users/symbadian/Desktop/LIRIS_new_dataset/WITH_BG_WITHAUGs/yolov5b/runs/train/Pre-Trained-weights/exp_yolov5m/weights/best.pt')

Hi @glenn-jocher and thanks so much for your swift response and your time, I really really appreciate this..

I am trying to interpret these errors so I realized that there was an indentation error so I fixed it, but that was not the real issue,

and I tried yours to see if it would the model from the link automatically, but that did not work as well..

@Symbadian I've already told you above not to load YAMLs. Please don't waste my time, I'm extremely busy.

@Symbadian I've already told you above not to load YAMLs. Please don't waste my time, I'm extremely busy.

forgive my lapse in understanding @glenn-jocher, I am really trying to get this going, please see below:

This worked for me:

Thanx for your patience and time, your efforts and guidance is highly valued!!

import torch
import torchvision
model = torch.hub.load('.', 'custom', path='/Users/symbadian/Desktop/LIRIS_new_dataset/WITH_BG_NoAUGs/yolov5/runs/train/From_Scratch/WITH_BG_NoAUGs/exp_yolov5m/weights/best.pt', source='local')
img = '/Users/symbadian/Desktop/LIRIS_new_dataset/WITH_BG_NoAUGs/yolov5/data/images/zidane.jpg'
results = model(img)
results.show()

@memelvin99 wave Hello! Thanks for asking about handling inference results. YOLOv5 rocket PyTorch Hub models allow for simple model loading and inference in a pure python environment without using detect.py.

Simple Inference Example

This example loads a pretrained YOLOv5s model from PyTorch Hub as model and passes an image for inference. 'yolov5s' is the YOLOv5 'small' model. For details on all available models please see the README. Custom models can also be loaded, including custom trained PyTorch models and their exported variants, i.e. ONNX, TensorRT, TensorFlow, OpenVINO YOLOv5 models.

import torch

# Model
model = torch.hub.load('ultralytics/yolov5', 'yolov5s')  # or yolov5m, yolov5l, yolov5x, etc.
# model = torch.hub.load('ultralytics/yolov5', 'custom', 'path/to/best.pt')  # custom trained 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
# 2  114.75  195.75  1095.0  708.0    0.624512      0  person
# 3  986.00  304.00  1028.0  420.0    0.286865     27     tie

See YOLOv5 PyTorch Hub Tutorial for details.

Good luck four_leaf_clover and let us know if you have any other questions!

It is not working. Can you please look into it.
