Example-Workflow¶

This chapter shows an example workflow for the current state of the project by using the CLI-client and the MNIST-dataset, which is also used for automated testing within the project. Beside this example-workflow it is also possible to use CSV-files instead of the MNIST-datasets, or interact directly with the neural network via the python-version of the SDK. See for further information the CLI and SDK documentation

Preparation¶

install Backend based on the Installation-guide

Download and unzip the MNIST-dataset for testing

wget https://storage.googleapis.com/cvdf-datasets/mnist/train-images-idx3-ubyte.gz
wget https://storage.googleapis.com/cvdf-datasets/mnist/train-labels-idx1-ubyte.gz
wget https://storage.googleapis.com/cvdf-datasets/mnist/t10k-images-idx3-ubyte.gz
wget https://storage.googleapis.com/cvdf-datasets/mnist/t10k-labels-idx1-ubyte.gz

unzip files so you have the local files:

train-images-idx3-ubyte
train-labels-idx1-ubyte
t10k-images-idx3-ubyte
t10k-labels-idx1-ubyte

Download the pre-build binary of the CLI-client from the file-share

Info

Because the rollout still use self-signed certificates, for the following hanamictl-commands the --insecure-flag has to be used to avoid tls-check. Will be changed in the near future.

Export env-variables for connect and login-information:

export HANAMI_ADDRESS=<ADDRESS_OF_HANAMI_DEPLOYMENT>
export HANAMI_USER=<USER_ID>
export HANAMI_PASSPHRASE=<USER_PASSPHRASE>

Example

export HANAMI_ADDRESS=https://local-hanami-new
export HANAMI_USER=asdf
export HANAMI_PASSPHRASE=asdfasdf

Example¶

Upload MNIST-dataset to backend

# train-data
./hanamictl dataset create mnist --insecure -i ./train-images-idx3-ubyte -l ./train-labels-idx1-ubyte train_data

# test-data
./hanamictl dataset create mnist --insecure -i ./t10k-images-idx3-ubyte -l ./t10k-labels-idx1-ubyte test_data

Example

./hanamictl dataset create mnist --insecure -i ./train-images-idx3-ubyte -l ./train-labels-idx1-ubyte train_data

Prepare cluster-template by writing the following example into a local file names cluster_template

version: 1
settings:
    neuron_cooldown: 10000000.0
    refractory_time: 1
    max_connection_distance: 1
    enable_reduction: false

hexagons:
    1,1,1
    2,1,1
    3,1,1

inputs:
    picture_hexagon: 1,1,1

outputs:
    label_hexagon: 3,1,1

Info

It is planned with version v0.6.0 to make these cluster-templates optional, so they are not required for such small examples anymore.

Create cluster from the template

./hanamictl cluster create --insecure -t ./cluster_template test_cluster

Example

./hanamictl cluster create --insecure -t ./cluster_template test_cluster

create task to train the cluster

./hanamictl task create train --insecure \
-i <UUID_OF_THE_TRAIN_DATASET>:picture:picture_hexagon \
-o <UUID_OF_THE_TRAIN_DATASET>:label:label_hexagon \
-c <UUID_OF_THE_CLUSTER> \
train_task

Info

The mapping of inputs and outputs is not optimal and will be updated in the near future.

Example

./hanamictl task create train --insecure \
-i 423ba6da-ca2a-4603-81bb-300326a10176:picture:picture_hexagon \

The task runs in the background by a task-queue. The status of the task can be checked with

./hanamictl task get --insecure -c <CLUSTER_UUID> <TASK_UUID>

+------------------------+--------------------------------------+

Info

With the python-SDK it is also possible to interact directly with the cluster. See direct-IO

create task to test the cluster

./hanamictl task create request --insecure \
-i <UUID_OF_THE_TEST_DATASET>:picture:picture_hexagon \
-r label_hexagon:test_output \
-c <UUID_OF_THE_CLUSTER> \
test_task

It will create a new dataset with name test_output where the output of the task is written into

Example

./hanamictl task create request --insecure \
-i a42dce48-d4b6-40f9-a8d8-0c22d48e2a4d:picture:picture_hexagon \

+------------------------+--------------------------------------+

check accuracy of the new resulting dataset

./hanamictl dataset check --insecure -r <UUID_OF_THE_TEST_DATASET> <UUID_OF_THE_NEW_CREATED_DATASET>

Info

This check only works for the MNIST-dataset and is primary for automated testing within the CI-pipeline.

./hanamictl dataset list --insecure

| ACCURACY | 91.86000061035156 |
+----------+-------------------+

(Running the train-task multiple times still increased the accuracy up to 95-96%)

get the part of the resulting dataset

./hanamictl dataset content --insecure -c test_output -o 100 -n 10 <UUID_OF_THE_NEW_CREATED_DATASET>

This prints the data of the lines 100 - 110 of the segment names test_output of the dataset

Example

./hanamictl dataset content --insecure -c test_output -o 100 -n 10  36f70489-c71c-48d7-9e08-a766507df5de
