How to print the output of the wrong prediction of validation dataset?

[zihangJiang]

You may refer to the code here to compare the output (prediction) and the target (ground truth).

TokenLabeling/validate.py

Lines 238 to 242 in 09bb641

	# measure accuracy and record loss
	acc1, acc5 = accuracy(output.detach(), target, topk=(1, 5))
	losses.update(loss.item(), input.size(0))
	top1.update(acc1.item(), input.size(0))
	top5.update(acc5.item(), input.size(0))

And if I want to get the dir with the prediction , ?

To get the path of the images, you may refer to

TokenLabeling/generate_label.py

Lines 110 to 128 in 09bb641

	class ImageDatasetWithIndex(ImageDataset):
	def __getitem__(self, index):
	img, target = self.parser[index]
	try:
	img = img.read() if self.load_bytes else Image.open(img).convert('RGB')
	except Exception as e:
	_logger.warning(f'Skipped sample (index {index}, file {self.parser.filename(index)}). {str(e)}')
	self._consecutive_errors += 1
	if self._consecutive_errors < _ERROR_RETRY:
	return self.__getitem__((index + 1) % len(self.parser))
	else:
	raise e
	self._consecutive_errors = 0
	if self.transform is not None:
	img = self.transform(img)
	if target is None:
	target = torch.tensor(-1, dtype=torch.long)
	return img, target, index

Is there no test.py to inference?

You can use this colab notebook for inference. It uses VOLO model, but you can simply change the model by from tlt.models import lvvit_s and download the pre-trained model here

Please use the latest version of our repo. (pip install tlt==0.2.0)
This is a bug of the function in tlt/utils.py in our early version which delete all classification heads in order to do transfer learning.

If I use model = lvvit_s(img_size=384), it loads the official model, but how to load my finetune model ？

[zihangJiang]

If the number of classes is not 1000, you should also pass num_classes to the model (i.e. model = lvvit_s(img_size=384, num_classes=2))

It does work, thank you
