PyTorchModel serverless deploy raises ClientError

[ManuConcepBrito]

Describe the bug
PytorchModel doesn't deploy in serverless mode.

To reproduce

image_uri = sagemaker.image_uris.retrieve(
        framework="pytorch",
        region="eu-central-1",
        py_version="py38",
        version='1.10',
        instance_type="ml.t2.xlarge",
        image_scope="inference"
    )
# not being used at the moment due to AWS bug
serverless_config = ServerlessInferenceConfig(
  memory_size_in_mb=4096,
  max_concurrency=10,
 )

  pytorch_model = PyTorchModel(model_data=path_to_s3,
                               role=role,
                               image_uri=image_uri,
                               source_dir="src",
                               entry_point="inference.py",
                               framework_version='1.10',
                               py_version='py38')
  predictor = pytorch_model.deploy(initial_instance_count=1, serverless_inference_config=serverless_config, endpoint_name=SERVERLESS_ENDPOINT_NAME)

Expected behavior
Model deployed in serverless mode

ClientError: An error occurred (ValidationException) when calling the CreateEndpoint operation: One or more endpoint features are not supported using this configuration

System information
A description of your system. Please provide:

• SageMaker Python SDK version: 2.80.0
• Framework name (eg. PyTorch) or algorithm (eg. KMeans): PyTorch
• Framework version: 1.10
• Python version: 3.8
• CPU or GPU: CPU and GPU
• Custom Docker image (Y/N): N

Additional context
The error happens also when specifying a CPU instance type (as I have read that GPU is not supported in serverless, not sure if this is still the case). Also logs are quite cryptic so I am not sure how to pinpoint the issue.

[schematical]

If anyone hits this in the future it turns out when creating the Endpoint Config manually in the UI I could trigger this error "Models requiring any of the following features are not supported on serverless endpoints: AWS marketplace model packages, private Docker registries, Multi-Model Endpoints, VPC configuration, network isolation."

But you dont get that if you use Terraform(and I am assuming the SDK/CLI). In my case I have a VPC Config. So double check you don't have any of those settings that are mentioned in that error message.
