一、YouTube-8M 初探（视频与音频分类）

不建议在win10上跑，最好使用ubuntu。

下载数据集

# Video-level
mkdir -p ~/yt8m/v2/video
cd ~/yt8m/v2/video
curl data.yt8m.org/download.py | shard=1,100 partition=2/video/train mirror=us python
curl data.yt8m.org/download.py | shard=1,100 partition=2/video/validate mirror=us python
curl data.yt8m.org/download.py | shard=1,100 partition=2/video/test mirror=us python

# Frame-level
mkdir -p ~/yt8m/v2/frame
cd ~/yt8m/v2/frame
curl data.yt8m.org/download.py | shard=1,100 partition=2/frame/train mirror=us python
curl data.yt8m.org/download.py | shard=1,100 partition=2/frame/validate mirror=us python
curl data.yt8m.org/download.py | shard=1,100 partition=2/frame/test mirror=us python

训练模型

python train.py --feature_names='mean_rgb,mean_audio' --feature_sizes='1024,128' --train_data_pattern=${HOME}/yt8m/v2/video/train*.tfrecord --train_dir ~/yt8m/v2/models/video/sample_model --start_new_model

验证模型

python eval.py --eval_data_pattern=${HOME}/yt8m/v2/video/validate*.tfrecord --train_dir ~/yt8m/v2/models/video/sample_model
