Hello, I can’t do `import wandb` and got following error after upgrading to wandb 0.16.6. My first guess is incompatibility of `protobuf`, but don’t know how to fix. My python version is 3.11. Please help, thank you.

Thank you so much for writing in, and apologies you are seeing this behavior.

`AttributeError: module 'wandb.proto.wandb_internal_pb2' has no attribute 'Result'"` - this error does seem to be coming from the protobuf version. Would you be able to try to downgrade your protobuf package to 3.20.x or lower?

Thank you for the reply! I’m using protobuf==4.25.3, which is automatically pinned by wandb. I used `pip-compile --generate-hashes --no-emit-index-url --strip-extras requirements.dev.in`, and that generated `requirements.dev.text` exactly:

```auto

from `requirements.dev.in`:

```auto

I didn’t have this problem before, so it is super confusing now…

Thank you for sending it over!

Could you try running `pip install protobuf==3.20.1` and see if that changes anything for you?

Could you also see if downgrading back to 0.16.5 resolves this concern for you, and its definitely something to do with 0.16.6?

Do you mean `protobuf==3.20.1` and `wandb==0.16.5` simultaneously? I have tried `wandb==0.16.5` and the error still exists. The version of `protobuf` is pinned by `wandb`, so I am unsure how to set `protobuf==3.20.1` for `wandb==0.16.5` manually …

Could you try running pip install protobuf==3.20.1?

It should install 3.20.1 to your current enviroment.
