RuntimeError: Could not infer dtype of numpy.float32

[hushuai1]

您好，我在用您的demo进行测试的时候遇到了这个问题， 好像是这句代码的问题，求指点 c = torch.tensor(labels[:, 0]) # classes Scanning labels DOTA_demo_view/labels.cache (44 found, 0 missing, 0 empty, 0 duplicate, for 44 images): 44it [00:00, 13217.03it/s] Traceback (most recent call last): File "train.py", line 724, in train(hyp, opt, device, tb_writer) File "train.py", line 311, in train c = torch.tensor(labels[:, 0]) # classes RuntimeError: Could not infer dtype of numpy.float32
