Timesformer Hr Finetuned K400

🚀 TimeSformer（高分辨率變體，在Kinetics - 400上微調）

TimeSformer模型在Kinetics - 400數據集上進行了預訓練。它由Tong等人在論文TimeSformer: Is Space - Time Attention All You Need for Video Understanding?中提出，並首次在此倉庫發佈。

免責聲明：發佈TimeSformer的團隊未為此模型編寫模型卡片，此模型卡片由fcakyon編寫。

🚀 快速開始

你可以使用該原始模型將視頻分類為400種可能的Kinetics - 400標籤之一。

💻 使用示例

基礎用法

from transformers import AutoImageProcessor, TimesformerForVideoClassification
import numpy as np
import torch

video = list(np.random.randn(16, 3, 448, 448))

processor = AutoImageProcessor.from_pretrained("facebook/timesformer-hr-finetuned-k400")
model = TimesformerForVideoClassification.from_pretrained("facebook/timesformer-hr-finetuned-k400")

inputs = processor(images=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])
