model torch.hub.load(ultralytics/yolov5, yolov5s)model torch.hub.load(ultralytics/yolov3, yolov3)I found yolov3.pt in Release. 参考 https://discuss.pytorch.org/t/using-torch-load-on-a-torch-hub-model/89365 https://docs.ultralytics.com/yolov5/tutorials/pytorch_hub_model_loading/#before-you-start
No module named ‘models’
In yolov3 ~ yolov7 repo directory,
import torch
# _model torch.hub.load(ultralytics/yolov5, yolov5s) # _model is the model itself
model torch.load(yolov3.pt, map_locationcpu)[model]
torch.save(model.state_dict(), yolov3.pth)But the pretrained weight seems not matched to yolov7_d2. Funny design of yolo pretrained model.
The following submodules of the model were never called during the trace of the graph.
定义的submodules没有用到可能出现在ddp的时候。移除即可。 The following submodules of the model were never called during the trace of the graph. They may be unused, or they were accessed by direct calls to .forward() or via other python methods. In the latter case they will have zeros for statistics, though their statistics will still contribute to their parent calling module.Inplace update to inference tensor outside inferencemode
Use torch.no_grad() instead of torch.inferece_mode(). Inference mode vs no_grad() Inplace update to inference tensor outside InferenceMode is not allowed.You can make a clone to get a normal tensor before doing inplace update.See https://github.com/pytorch/rfcs/pull/17 for more details.
One difference would be that you are not allowed to set the requires_grad attribute on tensors from an inference_mode context:
with torch.no_grad():x torch.randn(1)y x 1y.requires_grad True
z y 1
print(z.grad_fn)AddBackward0 object at 0x7fe9c6eafdf0with torch.inference_mode():x torch.randn(1)y x 1y.requires_grad TrueRuntimeError: Setting requires_gradTrue on inference tensor outside InferenceMode is not allowed.In a word, outside inference mode, inference tensor is still restricted.
