google-cloud-ml-engine

This repo will train the model on google cloud ml engine & host the model in ml engine.

Installation

Ludwig has been developed and tested with Python 3 in mind. If you don’t have Python 3 installed, install it by running:

# on ubuntu
sudo apt install python3 
# on mac 
brew install python3

Using local python

You can run the code locally

JOB_DIR=jobDir

Prediction using gcloud local

You can run prediction on the SavedModel created from Keras HDF5 model

gcloud ml-engine local predict --model-dir=./models/h5/export/1544372069/  --json-instances request.json

Prediction using Cloud ML Engine

You can perform prediction on Cloud ML Engine by following the steps below.
Create a model on Cloud ML Engine
Export the model binaries
Deploy the model to the prediction service
Run the online prediction

MODEL_NAME=skyl_flower
REGION=us-east1
VERSION=v1
MODEL_BINARIES=gs://skyl-dev-ml/aashishdahiya/flowers_aashishdahiya_testV3_20181205_134432/flowerv15/export/1544433235/
gcloud ml-engine models create $MODEL_NAME --regions $REGION
gcloud ml-engine versions create $VERSION --model $MODEL_NAME --origin $MODEL_BINARIES --runtime-version 1.10
gcloud ml-engine predict --model $MODEL_NAME --version v1 --json-instances ./request.json
