This example shows how to use Arena to submit a pytorch stand-alone job. This example will download the source code from git url.

  1. The first step is to check the available resources.

    ➜ arena top node
NAME                       IPADDRESS     ROLE    STATUS  GPU(Total)  GPU(Allocated)
cn-huhehaote.172.16.0.205  172.16.0.205  master  ready   0           0
cn-huhehaote.172.16.0.206  172.16.0.206  master  ready   0           0
cn-huhehaote.172.16.0.207  172.16.0.207  master  ready   0           0
cn-huhehaote.172.16.0.208  172.16.0.208  <none>  ready   4           0
cn-huhehaote.172.16.0.209  172.16.0.209  <none>  ready   4           0
cn-huhehaote.172.16.0.210  172.16.0.210  <none>  ready   4           0

Allocated/Total GPUs In Cluster:
0/12 (0%)

    There are 3 available nodes with GPU for running training jobs.

  2. Submit a pytorch training job, this example download the source code from Alibaba Cloud code.

    # Single gpu card 
➜ arena --loglevel info submit pytorch \
        --name=pytorch-local-git \
        --gpus=1 \
        --image=registry.cn-huhehaote.aliyuncs.com/lumo/pytorch-with-tensorboard:1.5.1-cuda10.1-cudnn7-runtime \
        --sync-mode=git \
        --sync-source=https://code.aliyun.com/370272561/mnist-pytorch.git \
        "python /root/code/mnist-pytorch/mnist.py --backend gloo"
configmap/pytorch-local-git-pytorchjob created
configmap/pytorch-local-git-pytorchjob labeled
pytorchjob.kubeflow.org/pytorch-local-git created
INFO[0000] The Job pytorch-local-git has been submitted successfully
INFO[0000] You can run `arena get pytorch-local-git --type pytorchjob` to check the job status

    the source code will be downloaded and extracted to the directory code/ of the working directory. The default working directory is /root, you can also specify by using --workingDir.

    If you are using the private git repo, you can use the following command：

    ➜ arena --loglevel info submit pytorch \
    --name=pytorch-local-git \
    --gpus=1 \
    --image=registry.cn-huhehaote.aliyuncs.com/lumo/pytorch-with-tensorboard:1.5.1-cuda10.1-cudnn7-runtime \
    --sync-mode=git \
    --sync-source=https://code.aliyun.com/370272561/mnist-pytorch.git \
    --env=GIT_SYNC_USERNAME=yourname \
    --env=GIT_SYNC_PASSWORD=yourpwd \
    "python /root/code/mnist-pytorch/mnist.py --backend gloo"

  3. List all the jobs.

    ➜ arena list
NAME                          STATUS     TRAINER     AGE  NODE
pytorch-local-git             SUCCEEDED  PYTORCHJOB  21h  N/A

  4. Get the details of the this job.

    ➜ arena get pytorch-local-git
STATUS: SUCCEEDED
NAMESPACE: default
PRIORITY: N/A
TRAINING DURATION: 35s

NAME               STATUS     TRAINER     AGE  INSTANCE                    NODE
pytorch-local-git  SUCCEEDED  PYTORCHJOB  23h  pytorch-local-git-master-0  172.16.0.210

  5. Check logs.

    ➜ arena logs pytorch-local-git
WORLD_SIZE: 1, CURRENT_RANK: 0
args: Namespace(backend='gloo', batch_size=64, data='/root/code/mnist-pytorch', dir='/root/code/mnist-pytorch/logs', epochs=1, log_interval=10, lr=0.01, momentum=0.5, no_cuda=False, save_model=False, seed=1, test_batch_size=1000)
