Load YOLOv5 from PyTorch Hub ⭐ #36
Comments
@glenn-jocher |
Can someone use the training script with this configuration ? |
Can I ask about the meaning of the output? |

@rlalpha I've updated pytorch hub functionality now in c4cb785 to automatically append an NMS module to the model when Anyone using YOLOv5 pretrained pytorch hub models directly for inference can now replicate the following code to use YOLOv5 without cloning the ultralytics/yolov5 repository. In this example you see the pytorch hub model detect 2 people (class 0) and 1 tie (class 27) in zidane.jpg. Note there is no repo cloned in the workspace. Also note that ideally all inputs to the model should be letterboxed to the nearest 32 multiple. The second best option is to stretch the image up to the next largest 32-multiple as I've done here with PIL resize. |
I got how to do it now. Thank you for rapid reply. |
@rlalpha @justAyaan @MohamedAliRashad this PyTorch Hub tutorial is now updated to reflect the simplified inference improvements in PR #1153. It's very simple now to load any YOLOv5 model from PyTorch Hub and use it directly for inference on PIL, OpenCV, Numpy or PyTorch inputs, including for batched inference. Reshaping and NMS are handled automatically. Example script is shown in above tutorial. |

@pfeatherstone thanks for the feedback! Can you try with import torch
model = torch.hub.load('ultralytics/yolov5', 'yolov5s', pretrained=True, force_reload=True) |
Still doesn't work. I get the following errors:
|
@pfeatherstone I've raised a new bug report in #1181 for your observation. This typically indicates a pip package called utils is installed in your environment, you should |
model = torch.hub.load('ultralytics/yolov5', 'yolov5s', _verbose=False) |
Can someone please look into this issue regarding yolov5 ...it is showing 'ultralytics' module not found while working in windows but the module is already installed but still it is showing error and the same code is working fine in colab. |
Same issue as @Prakhar2295. Hope for a fix soon. |
The above issue is still open |
Please check i have resolved this issue. |
How did you solve the problem? |
I want to detect windows and walls using object detection can anyone help me with this purpose? |
please display some demo images |
can you share your email please? |
[email protected], too busy to answer quickly |
Traceback (most recent call last): During handling of the above exception, another exception occurred: Traceback (most recent call last): The above exception was the direct cause of the following exception: Traceback (most recent call last): Here is the fix:import pathlib
temp = pathlib.PosixPath
pathlib.PosixPath = pathlib.WindowsPath |
Yes thats the correct solution, add this in the file where you are loading the model. |
import pathlib The above solution is not working @vinodbaste |
@vinodbaste solution recommended is not working Can anyone help me |
@glenn-jocher , Exception: [Errno 13] Permission denied: 'D:\update_infer\yolov5\best_openvino_model_16\openvino_model'. Cache may be out of date, try note: openvino_model folder contains all meta data information same as best_oprnvino_model folder |
This is working. |
📚 This guide explains how to load YOLOv5 🚀 from PyTorch Hub https://pytorch.org/hub/ultralytics_yolov5. See YOLOv5 Docs for additional details. UPDATED 26 March 2023.
Before You Start
Install requirements.txt in a Python>=3.7.0 environment, including PyTorch>=1.7. Models and datasets download automatically from the latest YOLOv5 release.
💡 ProTip: Cloning https://github.com/ultralytics/yolov5 is not required 😃
Load YOLOv5 with PyTorch Hub
Simple Example
This example loads a pretrained YOLOv5s model from PyTorch Hub as
model
and passes an image for inference.'yolov5s'
is the lightest and fastest YOLOv5 model. For details on all available models please see the README.Detailed Example
This example shows batched inference with PIL and OpenCV image sources.
results
can be printed to console, saved toruns/hub
, showed to screen on supported environments, and returned as tensors or pandas dataframes.For all inference options see YOLOv5
AutoShape()
forward method:yolov5/models/common.py
Lines 243 to 252 in 30e4c4f
Inference Settings
YOLOv5 models contain various inference attributes such as confidence threshold, IoU threshold, etc. which can be set by:
Device
Models can be transferred to any device after creation:
Models can also be created directly on any
device
:💡 ProTip: Input images are automatically transferred to the correct model device before inference.
Silence Outputs
Models can be loaded silently with
_verbose=False
:Input Channels
To load a pretrained YOLOv5s model with 4 input channels rather than the default 3:
In this case the model will be composed of pretrained weights except for the very first input layer, which is no longer the same shape as the pretrained input layer. The input layer will remain initialized by random weights.
Number of Classes
To load a pretrained YOLOv5s model with 10 output classes rather than the default 80:
In this case the model will be composed of pretrained weights except for the output layers, which are no longer the same shape as the pretrained output layers. The output layers will remain initialized by random weights.
Force Reload
If you run into problems with the above steps, setting
force_reload=True
may help by discarding the existing cache and force a fresh download of the latest YOLOv5 version from PyTorch Hub.Screenshot Inference
To run inference on your desktop screen:
Multi-GPU Inference
YOLOv5 models can be be loaded to multiple GPUs in parallel with threaded inference:
Training
To load a YOLOv5 model for training rather than inference, set
autoshape=False
. To load a model with randomly initialized weights (to train from scratch) usepretrained=False
. You must provide your own training script in this case. Alternatively see our YOLOv5 Train Custom Data Tutorial for model training.Base64 Results
For use with API services. See #2291 and Flask REST API example for details.
Cropped Results
Results can be returned and saved as detection crops:
Pandas Results
Results can be returned as Pandas DataFrames:
Pandas Output (click to expand)
Sorted Results
Results can be sorted by column, i.e. to sort license plate digit detection left-to-right (x-axis):
Box-Cropped Results
Results can be returned and saved as detection crops:
JSON Results
Results can be returned in JSON format once converted to
.pandas()
dataframes using the.to_json()
method. The JSON format can be modified using theorient
argument. See pandas.to_json()
documentation for details.JSON Output (click to expand)
Custom Models
This example loads a custom 20-class VOC-trained YOLOv5s model
'best.pt'
with PyTorch Hub.TensorRT, ONNX and OpenVINO Models
PyTorch Hub supports inference on most YOLOv5 export formats, including custom trained models. See TFLite, ONNX, CoreML, TensorRT Export tutorial for details on exporting models.
💡 ProTip: TensorRT may be up to 2-5X faster than PyTorch on GPU benchmarks
💡 ProTip: ONNX and OpenVINO may be up to 2-3X faster than PyTorch on CPU benchmarks
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):
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, validation, inference, export and benchmarks on MacOS, Windows, and Ubuntu every 24 hours and on every commit.
