Pytorch-yolov3: ValueError: not enough values to unpack (expected 3, got 0)

[cendelian]

hello
when i train, and it occur error as below:

File "/media/cendelian/新加卷/CV/Project/PyTorch-YOLOv3/test.py", line 53, in evaluate
true_positives, pred_scores, pred_labels = [np.concatenate(x, 0) for x in list(zip(*sample_metrics))]
ValueError: not enough values to unpack (expected 3, got 0)

could you help me

It seems the model is not trained well at first epoch. You can change the option evaluation_interval to 10 and train.py line 152 1 to 5. Then have a try.

@construct-care
Do you mean this train.py line 152 ?
if epoch % opt.evaluation_interval == 0: ?

Try to check this #222 @cendelian

Yes. Sorry. 0 to 5. You can have a try.
