👋 Hello! Thanks for asking about Export Formats. YOLOv5 🚀 offers export to almost all of the common export formats. See our TFLite, ONNX, CoreML, TensorRT Export Tutorial for full details.

Formats

YOLOv5 inference is officially supported in 11 formats:

💡 ProTip: Export to ONNX or OpenVINO for up to 3x CPU speedup. See CPU Benchmarks. 💡 ProTip: Export to TensorRT for up to 5x GPU speedup. See GPU Benchmarks.

Format	`export.py --include`	Model
PyTorch	-	`yolov5s.pt`
TorchScript	`torchscript`	`yolov5s.torchscript`
ONNX	`onnx`	`yolov5s.onnx`
OpenVINO	`openvino`	`yolov5s_openvino_model/`
TensorRT	`engine`	`yolov5s.engine`

Export a Trained YOLOv5 Model

This command exports a pretrained YOLOv5s model to TorchScript and ONNX formats. yolov5s.pt is the 'small' model, the second smallest model available. Other options are yolov5n.pt, yolov5m.pt, yolov5l.pt and yolov5x.pt, along with their P6 counterparts i.e. yolov5s6.pt or you own custom training checkpoint i.e. runs/exp/weights/best.pt. For details on all available models please see our README table.

python export.py --weights yolov5s.pt --include torchscript onnx

💡 ProTip: Add --half to export models at FP16 half precision for smaller file sizes

Output:

export: data=data/coco128.yaml, weights=['yolov5s.pt'], imgsz=[640, 640], batch_size=1, device=cpu, half=False, inplace=False, train=False, keras=False, optimize=False, int8=False, dynamic=False, simplify=False, opset=12, verbose=False, workspace=4, nms=False, agnostic_nms=False, topk_per_class=100, topk_all=100, iou_thres=0.45, conf_thres=0.25, include=['torchscript', 'onnx']

Mhamed26 commented 1 year ago

Hi, I am trying to export a custom model to the onnx format yet i am met with this error :

glenn-jocher commented 1 year ago

@Mhamed26 hello! Thank you for reaching out. This error might occur due to an issue with your custom model's architecture or parameters. We recommend reviewing and adjusting your model accordingly. Additionally, you can try checking the version of your PyTorch installation as well as ensuring that you have the latest version of ONNX packages installed. Please let us know if you have any further questions or concerns.

Mhamed26 commented 1 year ago

@glenn-jocher Can you provide me with additional insights on the requirements needed for this to work with a custom model ?

Mhamed26 commented 1 year ago

Update : in my case setting the opset to 12 solved the issue

bharath5673 commented 1 year ago

hi.... im trying to load onnx or engine file this way but im getting this error on the other hand it works well with .pt files..

import torch
model = torch.hub.load('ultralytics/yolov5', 'custom', path='yolov5s.onnx')  # local model

File "/home/bharath/anaconda3/envs/test/lib/python3.9/site-packages/onnxruntime/capi/onnxruntime_inference_collection.py", line 217, in run return self._sess.run(output_names, input_feed, run_options) onnxruntime.capi.onnxruntime_pybind11_state.InvalidArgument: [ONNXRuntimeError] : 2 : INVALID_ARGUMENT : Unexpected input data type. Actual: (tensor(float)) , expected: (tensor(float16))

glenn-jocher commented 1 year ago

@bharath5673 it looks like the error you're experiencing might be related to the data type of the input tensor when using the ONNX model. The error message indicates that the input data type is expected to be float16, but it's receiving float instead. You might need to ensure that your input data type matches the expected data type of your ONNX model.

If you have any further questions or need assistance, feel free to ask!
