Probably we should be pinning a more recent version of google.cloud libraries that are compatible, we're still researching this.\r\n\r\n#### Environment details\r\n\r\n  - OS type and version: image 1.4-ubuntu18 (GCP dataproc).\r\n  - Python version: 3.6\r\n  - pip version: `pip --version`\r\n  - `google-api-core` version: 1.19.0\r\n\r\n#### Steps to reproduce\r\n\r\n  1. See stack trace below, it happens on import bigquery client.\r\n\r\n#### Stack trace\r\n```\r\n    from google.cloud import bigquery, bigquery_storage, storage\r\n  File \"/opt/conda/default/lib/python3.6/site-packages/google/cloud/bigquery/__init__.py\", line 35, in \u003cmodule\u003e\r\n    from google.cloud.bigquery.client import Client\r\n  File \"/opt/conda/default/lib/python3.6/site-packages/google/cloud/bigquery/client.py\", line 58, in \u003cmodule\u003e\r\n    from google.cloud.bigquery import _pandas_helpers\r\n  File \"/opt/conda/default/lib/python3.6/site-packages/google/cloud/bigquery/_pandas_helpers.py\", line 25, in \u003cmodule\u003e\r\n    from google.cloud import bigquery_storage_v1beta1\r\n  File \"/opt/conda/default/lib/python3.6/site-packages/google/cloud/bigquery_storage_v1beta1/__init__.py\", line 26, in \u003cmodule\u003e\r\n    from google.cloud.bigquery_storage_v1beta1 import client\r\n  File \"/opt/conda/default/lib/python3.6/site-packages/google/cloud/bigquery_storage_v1beta1/client.py\", line 24, in \u003cmodule\u003e\r\n    import google.api_core.gapic_v1.method\r\n  File \"/opt/conda/default/lib/python3.6/site-packages/google/api_core/gapic_v1/__init__.py\", line 26, in \u003cmodule\u003e\r\n    from google.api_core.gapic_v1 import method_async  # noqa: F401\r\n  File \"/opt/conda/default/lib/python3.6/site-packages/google/api_core/gapic_v1/method_async.py\", line 20, in \u003cmodule\u003e\r\n    from google.api_core import general_helpers, grpc_helpers_async\r\n  File \"/opt/conda/default/lib/python3.6/site-packages/google/api_core/grpc_helpers_async.py\", line 145, in \u003cmodule\u003e\r\n    class _WrappedStreamUnaryCall(_WrappedUnaryResponseMixin, _WrappedStreamRequestMixin, aio.StreamUnaryCall):\r\nAttributeError: module 'grpc.experimental.aio' has no attribute 'StreamUnaryCall'\r\n```","author":{"url":"https://github.com/gtoonstra","@type":"Person","name":"gtoonstra"},"datePublished":"2020-06-05T07:49:12.000Z","interactionStatistic":{"@type":"InteractionCounter","interactionType":"https://schema.org/CommentAction","userInteractionCount":15},"url":"https://github.com/40/python-api-core/issues/40"}
