  ```

### Kubernetes Setup

* Create Azure Kubernetes Service

* Use node pools to add GPU nodes. https://docs.microsoft.com/en-us/azure/aks/use-multiple-node-pools

* Add Virtual Node add-on

```bash
    export VK_RELEASE=virtual-kubelet-latest
    export CHART_URL=https://github.com/virtual-kubelet/virtual-kubelet/raw/master/charts/$VK_RELEASE.tgz
    helm install --name vk "$CHART_URL" --namespace kube-system -f ./k8s/vk-helm-values.yaml
    ```

* Enable GPU's with daemonset. https://docs.microsoft.com/en-us/azure/aks/gpu-cluster

```bash
    kubectl create namespace gpu-resources
    kubectl apply -f ./k8s/nvidia-device-plugin-ds.yaml
    ```

* Storage (Azure Files Static)

> Azure Files Docs: https://docs.microsoft.com/en-us/azure/aks/azure-files-volume

```bash
    export AKS_PERS_STORAGE_ACCOUNT_NAME=briarmlwestnew
    export AKS_PERS_RESOURCE_GROUP=oss-summit-west-new
    export AKS_PERS_LOCATION=westus
    export AKS_PERS_SHARE_NAME=aksshare

# Create the storage account
    az storage account create -n $AKS_PERS_STORAGE_ACCOUNT_NAME -g $AKS_PERS_RESOURCE_GROUP -l $AKS_PERS_LOCATION --sku Standard_LRS

# Export the connection string as an environment variable, this is used when creating the Azure file share
    export AZURE_STORAGE_CONNECTION_STRING=`az storage account show-connection-string -n $AKS_PERS_STORAGE_ACCOUNT_NAME -g $AKS_PERS_RESOURCE_GROUP -o tsv`

# Create the file share
    az storage share create -n $AKS_PERS_SHARE_NAME

# Get storage account key
    STORAGE_KEY=$(az storage account keys list --resource-group $AKS_PERS_RESOURCE_GROUP --account-name $AKS_PERS_STORAGE_ACCOUNT_NAME --query "[0].value" -o tsv)

# Echo storage account name and key
    echo Storage account name: $AKS_PERS_STORAGE_ACCOUNT_NAME
    echo Storage account key: $STORAGE_KEY

kubectl create secret generic azure-file-secret --from-literal=azurestorageaccountname=$AKS_PERS_STORAGE_ACCOUNT_NAME --from-literal=azurestorageaccountkey=$STORAGE_KEY

kubectl create secret generic azure-file-secret --from-literal=azurestorageaccountname=$AKS_PERS_STORAGE_ACCOUNT_NAME --from-literal=azurestorageaccountkey=$STORAGE_KEY --namespace kubeflow

# Add persistent volume
    kubectl apply -f ./k8s/persistent-volume.yaml
    ```

### Kubernetes Jobs

* Kubernetes job

```bash
  kubectl apply -f ./k8s/job-preprocess.yaml

kubectl apply -f ./k8s/job-training.yaml

kubectl apply -f ./k8s/tensorboard.yaml
  ```

### Kubeflow

* Install Kubeflow (I am using v0.5.0) https://www.kubeflow.org/docs/started/getting-started-k8s

```bash
  export KFAPP=kf-app-got-3
  kfctl init ${KFAPP}
  cd ${KFAPP}
  kfctl generate all -V
  kfctl apply all -V
  ```

* Validate Kubeflow

```bash
  kubectl -n kubeflow get all
  ```

* Execute TFJob

```bash
  # cpu
  kubectl apply -f ./k8s/tfjob-training.yaml

# gpu
  kubectl apply -f ./k8s/tfjob-training-gpu.yaml

# aci
  kubectl apply -f ./k8s/tfjob-training-vk.yaml

# Azure Premium Files
  kubectl apply -f ./k8s/tfjob-training-prem.yaml
  ```

* Deploy Serving

```bash
  kubectl apply -f ./k8s/serving.yaml
  ```

```bash
  docker cp tf-output/latest_model/exported_model serving_base:/models/inception

docker commit --change "ENV MODEL_NAME inception" serving_base chzbrgr71/got-tfserving:1.0
  ```

* Deploy Tensorboard

```bash
  kubectl apply -f ./k8s/tensorboard.yaml
  ```

* Kubeflow Pipelines

* Create a clean Python 3 environment

```bash
    conda create --name mlpipeline python=3.7
    source activate mlpipeline
    pip install -r ./pipelines/requirements.txt --upgrade
    ```

* Compile pipeline

```bash
    source activate mlpipeline
    python3 ./pipelines/pipeline.py
    ```
  
  * For now, there are a couple manual edits needed on the pipeline.yaml
    * environment variables (KUBE_POD_NAME in training)
    * volumes for Azure files

![Kubeflow Pipeline](https://raw.githubusercontent.com/chzbrgr71/got-image-classification/master/img/pipeline.png "Kubeflow Pipeline")

### Jupyter Notebooks

* Via port-forward to notebook instance

```bash
    kubectl port-forward brian-testing-01-0 -n kubeflow 8888:8888
    ```

http://localhost:8888/notebook/kubeflow/brian-testing-01

* Access via Traefik ingress. http://jupyter.brianredmond.io/notebook/kubeflow/brian-testing-01

### Hyperparameter Optimization

* Using Helm chart and AKS Virtual Nodes with GPU:

```bash
    helm install --name hyperparam ./hyperparameter/chart

kubectl apply -f ./hyperparameter/tensorboard-hp.yaml
    ```

* katib

```bash
    kubectl apply -f ./katib/random-example.yaml
    
    kubectl apply -f ./katib/got.yaml
    ```

### Inference

* Local python script

```bash
  # testing

### Tensorflow Lite

* Convert model

```bash
  IMAGE_SIZE=299
  tflite_convert \
    --graph_def_file=./tf-output/latest_model/got_retrained_graph.pb \
    --output_file=./tf-output/latest_model/optimized_graph.lite \
    --input_format=TENSORFLOW_GRAPHDEF \
    --output_format=TFLITE \
    --input_shape=1,${IMAGE_SIZE},${IMAGE_SIZE},3 \
    --input_array=Mul \
    --output_array=final_result \
    --inference_type=FLOAT \
    --input_data_type=FLOAT
  ```

* In container

```bash
  export IMAGE_TAG=2.00
  export ACRNAME=gotcr

# build/push (ACR or Docker)
  az acr build -t chzbrgr71/tflite-convert:$IMAGE_TAG -r $ACRNAME -f ./convert/Dockerfile ./convert

docker build -t chzbrgr71/tflite-convert:$IMAGE_TAG -f ./convert/Dockerfile ./convert
  docker push chzbrgr71/tflite-convert:$IMAGE_TAG

# run
  docker run -d --name convert --volume /Users/brianredmond/gopath/src/github.com/chzbrgr71/got-image-classification/tf-output:/tf-output chzbrgr71/tflite-convert:$IMAGE_TAG \
    --graph_def_file=./tf-output/latest_model/got_retrained_graph.pb \
    --output_file=./tf-output/latest_model/optimized_graph.lite \
    --input_format=TENSORFLOW_GRAPHDEF \

    --inference_type=FLOAT \
    --input_data_type=FLOAT
  ```

```bash
  kubectl apply -f ./k8s/convert.yaml
  ```

### ONNX

* This doesn't work at all: 
  
  ```bash
  source activate mlpipeline

python -m tf2onnx.convert \
    --saved-model ./tf-output/latest_model/exported_model/1/ \
    --output ./tf-output/onnx/model.onnx \
    --verbose

python -m tf2onnx.convert \
    --input ./tf-output/latest_model/got_retrained_graph.pb \
    --inputs DecodeJpeg/contents:0 \
    --outputs final_result:0 \
    --output ./tf-output/onnx/model.onnx \
    --verbose

saved_model_cli show --dir /got-image-classification/tf-output/latest_model/exported_model/1/ --tag_set serve --signature_def serving_default

export IMAGE_TAG=2.00
  export ACRNAME=gotcr

# build/push (ACR or Docker)
  az acr build -t chzbrgr71/onnx-convert:$IMAGE_TAG -r $ACRNAME -f ./onnx/Dockerfile ./onnx

docker build -t chzbrgr71/onnx-convert:$IMAGE_TAG -f ./onnx/Dockerfile ./onnx
  docker push chzbrgr71/onnx-convert:$IMAGE_TAG

docker run -d --name onnx --volume /Users/brianredmond/gopath/src/github.com/chzbrgr71/got-image-classification:/got-image-classification chzbrgr71/onnx-convert:1.1 "show" "--dir" "/got-image-classification/tf-output/latest_model/exported_model/1/" "--tag_set" "serve" "--signature_def" "serving_default"
  ```

### Tensorflow.js

* This doesn't work at all:

```bash
  pip install tensorflowjs==0.8.5 --force-reinstall
  pip install tensorflowjs==1.0.1 --force-reinstall

tensorflowjs_converter \
      --input_format=tf_saved_model \
      --output_format=tfjs_graph_model \
      --skip_op_check SKIP_OP_CHECK \
      ./tf-output/latest_model/got_retrained_graph.pb \
      ./tf-output/javascript

tensorflowjs_converter \
      --input_format=tf_saved_model \
      --output_format=tfjs_graph_model \
      --skip_op_check SKIP_OP_CHECK \
      ./tf-output/latest_model/exported_model/1 \
      ./tf-output/javascript

--output_node_names='final_result' \
  ```
