1.训练模型：建bucket，建job，提交运行。

BUCKET_NAME=gs://${USER}_yt8m_train_bucket_logisticmodel
# (One Time) Create a storage bucket to store training logs and checkpoints.
gsutil mb -l us-east1 $BUCKET_NAME
# Submit the training job.
JOB_NAME=yt8m_train_LogisticModel$(date +%Y%m%d_%H%M%S); gcloud --verbosity=debug ml-engine jobs 
submit training $JOB_NAME 
--package-path=youtube-8m --module-name=youtube-8m.train 
--staging-bucket=$BUCKET_NAME --region=us-east1 
--config=youtube-8m/cloudml-gpu.yaml 
-- --train_data_pattern='gs://youtube8m-ml-us-east1/1/video_level/train/train*.tfrecord' 
--model=LogisticModel 
--train_dir=$BUCKET_NAME/yt8m_train_video_level_logistic_model



BUCKET_NAME=gs://${USER}_yt8m_train_bucket_lstmmodel
gsutil mb -l us-east1 $BUCKET_NAME
JOB_NAME=yt8m_train_LstmModel$(date +%Y%m%d_%H%M%S); gcloud --verbosity=debug ml-engine jobs 
submit training $JOB_NAME 
--package-path=youtube-8m --module-name=youtube-8m.train 
--staging-bucket=$BUCKET_NAME --region=us-east1 
--config=youtube-8m/cloudml-gpu.yaml 
-- --train_data_pattern='gs://youtube8m-ml-us-east1/1/frame_level/train/train*.tfrecord' 
--frame_features=True --model=LstmModel --feature_names="rgb" 
--feature_sizes="1024" --batch_size=128 
--train_dir=$BUCKET_NAME/yt8m_train_frame_level_lstmModel


BUCKET_NAME=gs://${USER}_yt8m_train_bucket_framelevellogisticmodel
gsutil mb -l us-east1 $BUCKET_NAME
JOB_NAME=yt8m_train_FrameLevelLogisticModel$(date +%Y%m%d_%H%M%S); gcloud --verbosity=debug ml-engine jobs 
submit training $JOB_NAME 
--package-path=youtube-8m --module-name=youtube-8m.train 
--staging-bucket=$BUCKET_NAME --region=us-east1 
--config=youtube-8m/cloudml-gpu.yaml 
-- --train_data_pattern='gs://youtube8m-ml-us-east1/1/frame_level/train/train*.tfrecord' 
--frame_features=True --model=FrameLevelLogisticModel --feature_names="rgb" 
--feature_sizes="1024" --batch_size=128 
--train_dir=$BUCKET_NAME/yt8m_train_video_framelevel_logisticmodel


BUCKET_NAME=gs://${USER}_yt8m_train_bucket_dbofmodel
gsutil mb -l us-east1 $BUCKET_NAME
JOB_NAME=yt8m_train_DbofModel$(date +%Y%m%d_%H%M%S); gcloud --verbosity=debug ml-engine jobs 
submit training $JOB_NAME 
--package-path=youtube-8m --module-name=youtube-8m.train 
--staging-bucket=$BUCKET_NAME --region=us-east1 
--config=youtube-8m/cloudml-gpu.yaml 
-- --train_data_pattern='gs://youtube8m-ml-us-east1/1/frame_level/train/train*.tfrecord' 
--frame_features=True --model=DbofModel --feature_names="rgb" 
--feature_sizes="1024" --batch_size=128 
--train_dir=$BUCKET_NAME/yt8m_train_frame_level_dbofmodel

2.查看log,训练过程

点击侧边栏的logging可以查看程序输出。

tensorboard:https://cloud.google.com/ml-engine/docs/how-tos/getting-started-training-prediction#tensorboard-local

OUTPUT=$BUCKET_NAME/yt8m_train_video_framelevel_logisticmodel       （就是填入train_dir的内容）

python -m tensorflow.tensorboard --logdir=$OUTPUT --port=8080

Select "Preview on port 8080" from the Web Preview menu at the top of the command-line.

3.在测试集上进行测试：

JOB_TO_EVAL=yt8m_train_video_level_logistic_model
JOB_NAME=yt8m_inference_$(date +%Y%m%d_%H%M%S); gcloud --verbosity=debug ml-engine jobs 
submit training $JOB_NAME 
--package-path=youtube-8m --module-name=youtube-8m.inference 
--staging-bucket=$BUCKET_NAME --region=us-east1 
--config=youtube-8m/cloudml-gpu.yaml 
-- --input_data_pattern='gs://youtube8m-ml/1/video_level/test/test*.tfrecord' 
--train_dir=$BUCKET_NAME/${JOB_TO_EVAL} 
--output_file=$BUCKET_NAME/${JOB_TO_EVAL}/predictions.csv

JOB_NAME=yt8m_dbofmodel_inference_$(date +%Y%m%d_%H%M%S); gcloud --verbosity=debug ml-engine jobs 
submit training $JOB_NAME 
--package-path=youtube-8m --module-name=youtube-8m.inference 
--staging-bucket=$BUCKET_NAME --region=us-east1 
--config=youtube-8m/cloudml-gpu.yaml 
-- --input_data_pattern='gs://youtube8m-ml-us-east1/1/frame_level/test/test*.tfrecord' 
--frame_features=True --model=FrameLevelLogisticModel --feature_names="rgb" 
--feature_sizes="1024" --batch_size=128 
--train_dir=$BUCKET_NAME/${JOB_TO_EVAL} 
--output_file=$BUCKET_NAME/${JOB_TO_EVAL}/predictions.csv

JOB_NAME=yt8m_framelevellogistic_inference_$(date +%Y%m%d_%H%M%S); gcloud --verbosity=debug ml-engine jobs 
submit training $JOB_NAME 
--package-path=youtube-8m --module-name=youtube-8m.inference 
--staging-bucket=$BUCKET_NAME --region=us-east1 
--config=youtube-8m/cloudml-gpu.yaml 
-- --input_data_pattern='gs://youtube8m-ml-us-east1/1/frame_level/test/test*.tfrecord' 
--frame_features=True --model=FrameLevelLogisticModel --feature_names="rgb" 
--feature_sizes="1024" --batch_size=128 
--train_dir=$BUCKET_NAME/${JOB_TO_EVAL} 
--output_file=$BUCKET_NAME/${JOB_TO_EVAL}/predictions.csv
