Can't train from scratch!

[msadoun]

whenever I use this command: train.py --weights '' --cfg yolov3-spp.cfg --epochs 273 --batch 16 --accum 4 --multi

it gives me this response

I wanna train the network from scratch but it keeps asking about YOLO weights

[glenn-jocher]

@msadoun try single or double quotes. Your argparser arguments show 4 values weights="''" which is wrong. You only want 2 weights=''

[msadoun]

I used [weights=""] and now it shows me this:

how can I solve this

[aisulhaq]

when i run this command !python3 train.py --data'' data/roboflow.data --epochs 300

I get this error please help Namespace(accumulate=4, adam=False, batch_size=16, bucket='', cache_images=False, cfg='cfg/yolov3-spp.cfg', data='data/roboflow.data', device='', epochs=300, evolve=False, img_size=[416], multi_scale=False, name='', nosave=False, notest=False, rect=False, resume=False, single_cls=False, var=None, weights='weights/yolov3-spp-ultralytics.pt') Using CUDA device0 _CudaDeviceProperties(name='Tesla T4', total_memory=15109MB)

@aisulhaq please use the YOLOv5 repo for the most up to date YOLO training code. You can train YOLOv3 models there as well: https://github.com/ultralytics/yolov5
