07.Extras

Prepare the Dataset

• Gather images

• Label the images with LabelImg found at https://github.com/tzutalin/labelImg

• Generate CSV files from your labeled dataset using script found at https://github.com/datitran/raccoon_dataset/blob/master/xml_to_csv.py

• Convert the CSV files into your TFRecord Dataset using script found at https://github.com/datitran/raccoon_dataset/blob/master/generate_tfrecord.py

• Create your label map file.


Prepare the Dataset


Set Up Google Cloud Account

• Sign up for a Google Cloud Account

• Set up a project named CountingSheep

• Enable ML Engine for your project https://console.cloud.google.com/flows/enableapi?apiid=ml.googleapis.com

• Click “Storage” on the side bar, and then create a new bucket called CountingSheepData

• Create a sub-directory called “data” in your storage bucket


Set Up Your Docker Environment

• Download Docker from docker.io

• Download the Dockerfilehttps://github.com/tensorflow/models/blob/master/research/object_detection/dockerfiles/android/Dockerfile

• docker build .

• docker images

• docker run -it IMAGE_ID


Configure your local Google Cloud environment

• Login - gcloud auth login

• Set your google cloud project - gcloud config set project YOUR_PROJECT_NAME

• Set your storage bucket - gsutil mb gs://YOUR_UNIQUE_BUCKET_NAME

• Export Google Cloud project/bucket names - export PROJECT="YOUR_PROJECT_ID"

export YOUR_GCS_BUCKET="YOUR_UNIQUE_BUCKET_NAME"


Configure your local Google Cloud environment

• Get the name of your service account:-curl -H "Authorization: Bearer $(gcloud auth print-access-token)" https://ml.googleapis.com/v1/projects/${PROJECT}:getConfig

• Using the tpuServiceAccount value from the response. Export the TPU service account with the following command:-

- export TPU_ACCOUNT=your-service-account

• Grant ML service agent to TPU service account:-gcloud projects add-iam-policy-binding $PROJECT --member serviceAccount:$TPU_ACCOUNT --role roles/ml.serviceAgent


Set up Object Detection API

• Ensure your local copy of object detection API works with following commands:cd /tensorflow/models/researchpython object_detection/builders/model_builder_test.py



• Move your TFRecord files and label map from your host machine into your docker imagedocker cp train.record CONTAINERNAME:/train.recorddocker cp test.record CONTAINERNAME:/test.recorddocker cp sheep_label_map.pbtxt CONTAINERNAME:/ sheep_label_map.pbtxt

• Copy the data over to your bucket (from your docker container)gsutil -m cp -r /train.record gs://${YOUR_GCS_BUCKET}/data/gsutil -m cp -r /test.record gs://${YOUR_GCS_BUCKET}/data/gsutil cp /sheep_label_map.pbtxt gs://${YOUR_GCS_BUCKET}/data/



• Download the object detection model:curl –O http://download.tensorflow.org/models/object_detection/ssd_mobilenet_v1_0.75_depth_300x300_coco

14_sync_2018_07_03.tar.gztar xzf ssd_mobilenet_v1_0.75_depth_300x300_coco14_sync_2018_07_03.tar.gz

• Upload it to Google cloudgsutil cp /tmp/ssd_mobilenet_v1_0.75_depth_300x300_coco14_sync_2018_07_03/model.ckpt.*

gs://${YOUR_GCS_BUCKET}/data/



• Update the following values in the config file:/tensorflow/models/research/object_detection/samples/configs/ssd_mobilenet_v1_0.75_depth_quantized_300x300_pets_sync.config

Upload file to Google Cloud bucket with the following command:gsutil cp

/tensorflow/models/research/object_detection/samples/configs/ssd_mobilenet_v1_0.75_depth_quantized_300x300_pets_sync.config gs://${YOUR_GCS_BUCKET}/data/pipeline.config

• Package the object detection API with the following commands:bash object_detection/dataset_tools/create_pycocotools_package.sh /tmp/pycocotoolspython setup.py sdist


Train your model

• Start your training job on Google Cloud TPU with the following command:cd /tensorflow/models/researchgcloud ml-engine jobs submit training `whoami`_object_detection_`date +%s` --job-dir=gs://${YOUR_GCS_BUCKET}/train --packages dist/object_detection-0.1.tar.gz,slim/dist/slim-
