I have the same problem when (re)training a yolov5 model with the instructions provided: ... anchors, shape = self.anchors[i], p[i].shape AttributeError: 'list' object has no attribute 'shape' using the command python train.py --img 640 --epochs 3 --data data.yaml --weights yolov5s-seg.pt no changes to the loss.py or the repo in general

February 13, 2023 - Search before asking I have searched the YOLOv5 issues and found no similar bug report. YOLOv5 Component Training Bug Environment No response Minimal Reproducible Example No response Additional No ...

June 14, 2021 - Based on the error messages it seems that feats is a list, while you are trying to use it as a tensor. You could thus make sure that the forward method of your model returns a tensor or convert the list to a tensor using e.g. torch.stack · Yes, Python lists don’t have the clone() or shape ...

February 6, 2023 - I hoped that I can use yolov5s from hub as plug in play in my standard code that works with pytorch resnet model, but somehow it does not work and I cannot figure out what’s the issue. I need to train a model first. Here is the link The standard training piece of code looks like for i, (imgs, annotations) in enumerate(data_loader): imgs = list(img.to(device) for img in imgs) annotations = [{k: v.to(device) for k, v in t.items()} for t in annotations] ...
