ML Engine Runtime version and Python version not supported

Question

I am trying to run Google clound ml-engine following this tutorial, when executing this command :

$ gcloud ml-engine jobs submit training `whoami`_object_detection_`date +%s` \ 
    --job-dir=gs://${YOUR_GCS_BUCKET}/train\
    --packages dist/object_detection-0.1.tar.gz,slim/dist/slim-0.1.tar.gz,/tmp/pycocotools/pycocotools-2.0.tar.gz\
    --module-name object_detection.model_tpu_main \
    --runtime-version 1.10\
    --scale-tier BASIC_TPU\
    --region us-central1\
    --
    --model_dir=gs://${YOUR_GCS_BUCKET}/train
    --tpu_zone us-central1
    --pipeline_config_path=gs://${YOUR_GCS_BUCKET}/data/pipeline.config 

commands which answers me :

  ERROR: (gcloud.ml-engine.jobs.submit.training) INVALID_ARGUMENT: Field: runtime_version Error: The specified runtime version '1.10' with the Python version '' is not supported for TPU training.  Please specify a different runtime version. See https://cloud.google.com/ml/docs/concepts/runtime-version-list for a list of supported versions
- '@type': type.googleapis.com/google.rpc.BadRequest

  See https://cloud.google.com/ml/docs/concepts/runtime-version-list for a list

field: runtime_version

Because no version of python is detected, I added a --config=config.yaml argument to the command line:

config.yaml:

trainingInput:
  pythonVersion: "3.5"

but the problem barely changed :

...
 - description: The specified runtime version '1.10' with the Python version '3.5'
...

the runtime version list specify that runtime-version 1.10 is compatible with python 3.5, I also tried different runtime environement / python version which are required to work but my command keeps failling.

@jdehesa is right, the supported version is 1.9. The version 1.10 is not supported for training Cloud TPU models. change the runtime version editing this flag:

--runtime-version 1.9
