这个错误，可以解决 # num_workers=args.workers 改为num_workers = 0

但是然后转到generator.py，又在这个类报错了 C:\Users\Ni\AppData\Local\Programs\Python\Python38\python.exe F:/pycharm2020.2/crnn.pytorch_generator/train.py Namespace(batch_size=64, device='cuda', direction='horizontal', dist_backend='nccl', dist_url='env://', distributed=False, epochs=90, init_epoch=0, local_rank=0, lr=0.01, lr_gamma=0.1, lr_step_size=30, momentum=0.9, output_dir='./output', sync_bn=False, weight_decay=1e-05, workers=4, world_size=1) 0%| | 0/18 [00:00<?, ?it/s] Traceback (most recent call last): File "F:/pycharm2020.2/crnn.pytorch_generator/train.py", line 195, in train(arguments) File "F:/pycharm2020.2/crnn.pytorch_generator/train.py", line 140, in train loss = train_one_epoch(model, criterion, optimizer, data_loader, device, epoch, args) File "F:/pycharm2020.2/crnn.pytorch_generator/train.py", line 65, in train_one_epoch for image, target, input_len, target_len in tqdm(data_loader): File "C:\Users\Ni\AppData\Local\Programs\Python\Python38\lib\site-packages\tqdm\std.py", line 1165, in iter for obj in iterable: File "C:\Users\Ni\AppData\Local\Programs\Python\Python38\lib\site-packages\torch\utils\data\dataloader.py", line 521, in next data = self._next_data() File "C:\Users\Ni\AppData\Local\Programs\Python\Python38\lib\site-packages\torch\utils\data\dataloader.py", line 561, in _next_data data = self._dataset_fetcher.fetch(index) # may raise StopIteration File "C:\Users\Ni\AppData\Local\Programs\Python\Python38\lib\site-packages\torch\utils\data_utils\fetch.py", line 49, in fetch data = [self.dataset[idx] for idx in possibly_batched_index] File "C:\Users\Ni\AppData\Local\Programs\Python\Python38\lib\site-packages\torch\utils\data_utils\fetch.py", line 49, in data = [self.dataset[idx] for idx in possibly_batched_index] File "F:\pycharm2020.2\crnn.pytorch_generator\generator.py", line 181, in getitem image, indices, target_len = self.gen_image() File "F:\pycharm2020.2\crnn.pytorch_generator\generator.py", line 158, in gen_image text = np.random.choice(FONT_CHARS_DICT[font_path], target_len) File "mtrand.pyx", line 908, in numpy.random.mtrand.RandomState.choice ValueError: 'a' cannot be empty unless no samples are taken
