TimeSformer模型在 Kinetics-400 上进行了预训练。它由Tong等人在 TimeSformer: Is Space-Time Attention All You Need for Video Understanding? 的论文中引入,并于 this repository 首次发布。
免责声明:发布TimeSformer的团队没有为此模型撰写模型卡,因此此模型卡是由 fcakyon 撰写的。
您可以使用原始模型对视频进行分类,其中包括400个可能的Kinetics-400标签之一。
使用此模型对视频进行分类的方法如下:
from transformers import AutoImageProcessor, TimesformerForVideoClassification import numpy as np import torch video = list(np.random.randn(8, 3, 224, 224)) processor = AutoImageProcessor.from_pretrained("facebook/timesformer-base-finetuned-k400") model = TimesformerForVideoClassification.from_pretrained("facebook/timesformer-base-finetuned-k400") inputs = processor(video, return_tensors="pt") with torch.no_grad(): outputs = model(**inputs) logits = outputs.logits predicted_class_idx = logits.argmax(-1).item() print("Predicted class:", model.config.id2label[predicted_class_idx])
