# Distributed TensorFlow
|
|
|
|
TensorFlow is an open source software library for numerical computation using data flow graphs, and it supports distributed computing, allowing 'data parallel' or 'model parallel' on different servers. This means data scientists can now scale out distributed training to 100s of GPUs using TensorFlow.

|
## Prerequisites
|
|
|
|
- Kubernetes cluster v1.8+
|
|
|
|
## Chart Details
|
|
|
|
This chart will create a TensorFlow cluster, and distribute a computation graph across that cluster.
|
|
|
|
## Installing the Chart
|
|
|
|
* To install the chart with the release name `mnist`:
|
|
|
|
```bash
|
|
$ helm install --name mnist incubator/distributed-tensorflow
|
|
```
|
|
|
|
* To install with custom values via file:
|
|
|
|
```
|
|
$ helm install --values values.yaml --name mnist incubator/distributed-tensorflow
|
|
```
|
|
|
|
Below is an example of the custom value file values.yaml with GPU support.
|
|
|
|
```
|
|
worker:
|
|
number: 2
|
|
podManagementPolicy: Parallel
|
|
image:
|
|
repository: cheyang/distributed-tf
|
|
tag: 1.6.0-gpu
|
|
port: 9090
|
|
gpuCount: 1
|
|
|
|
ps:
|
|
number: 2
|
|
podManagementPolicy: Parallel
|
|
image:
|
|
repository: cheyang/distributed-tf
|
|
tag: 1.6.0
|
|
pullPolicy: IfNotPresent
|
|
port: 8080
|
|
|
|
# optimize for training
|
|
hyperparams:
|
|
batchsize: 20
|
|
learningrate: 0.001
|
|
```
|
|
|
|
> Notice: you can check the details of docker image from [Docker hub](https://hub.docker.com/r/cheyang/distributed-tf/)
|
|
|
|
## Uninstalling the Chart
|
|
|
|
* To uninstall/delete the `mnist` deployment:
|
|
|
|
```bash
|
|
$ helm delete mnist
|
|
```
|
|
|
|
The command removes all the Kubernetes components associated with the chart and deletes the release.
|
|
|
|
## Configuration
|
|
|
|
The following table lists the configurable parameters of the Service Distributed Tensorflow
|
|
chart and their default values.
