There is a deps conflict. Even pandas-gbq is the only package in the project.

To reporduce

1. poetry init
2. poetry add pandas-gbq

I don't think pandas-gbq requires protobuf directly (https://github.com/pydata/pandas-gbq/blob/master/setup.py)

So I'm guessing this is an issue with one of pandas-gbq's dependencies?

[tswast]

Both google-cloud-bigquery and google-cloud-bigquery-storage require protobuf.

• google-cloud-bigquery because of BQML resources
• google-cloud-bigquery-storage because of GRPC

[wasdee]

python-bigquery-storage -> python-api-core -> "protobuf >= 3.4.0"

Not sure which package on require protobuf==3.12.0

[tswast]

We recently added a direct dependency on protobuf>=3.12.0 in the google-cloud-bigquery package. googleapis/python-bigquery#306 Even though this is redundant with some google-api-core dependencies, it does allow us to test explicitly the minimum version over there.

We had a similar problem with the pyarrow dependency recently. #324 I marked that as fixed by updating the dependency on google-cloud-bigquery to include the necessary "extras" from that package.

@CircleOnCircles As we've made several changes to dependencies since this was opened, I'm going to mark this as closed, but please do re-open / let us know if it is not fixed in 0.14.0
