Description
We observe a stack trace on one of our clusters due to a package upgrade, possibly introduced by the new release of python-api-core, which we don't pin to a specific version.
Due to PR#29, we now see the following error:
'grpc.experimental.aio' has no attribute 'StreamUnaryCall'
We will pin our version to the previous one, but documenting this here as it can affect other customers. Probably we should be pinning a more recent version of google.cloud libraries that are compatible, we're still researching this.
Environment details
- OS type and version: image 1.4-ubuntu18 (GCP dataproc).
- Python version: 3.6
- pip version:
pip --version google-api-coreversion: 1.19.0
Steps to reproduce
- See stack trace below, it happens on import bigquery client.
