Unclear error in AzureML Computer job

- If the issue is to do with Azure CLI 2.0 in-particular, create an issue here at [Azure/azure-cli](https://github.com/Azure/azure-cli/issues)

### Extension name (the extension in question)
I am using the Azure ML 2.0 CLI.

### Description of issue (in as much detail as possible)

I built a container that I upload to ACR with my code and artifacts in place. I can run the container locally and get its to start successfully. The entry point starts from `/opt/main.py`. However, when I run it into Azure ML, it abruptly breaks with the status below.

> AzureMLCompute job failed.
> JobFailed: Submitted script failed with a non-zero exit code; see the driver log file for details.
> Reason: Job failed with non-zero exit Code

My YAML that I am launching the CLI with is as follows:

> $schema: https://azuremlschemas.azureedge.net/latest/commandJob.schema.json
> command: >-
> python /opt/main.py --set
> training-data={inputs.training}
> validation-data={inputs.validation}
> testing-data={inputs.testing}
> inputs:
> training:
> data:

> experiment_name: sk_learn
> description: Train a sklearn model

When I go to the driver logs, this is all that's there.
