I have an issue that seems to have been raised in a few other threads but for some reason none of those solutions are working for me. I am running `wandb.login()` in a jupyter notebook and receiving the following error:

```auto

```

I am using wandb version `0.16.1`. As you can see I am executing the code from within a jupyter notebook launched from a bazel server.

From [this post](https://community.wandb.ai/t/unable-to-login/4335) it seems wandb can’t find a python interpreter in my environment. The output of `print(sys.executable)` is `/private/var/tmp/_bazel_me/c6c153b8ee296ecf5ef55e689ef4faf0/execroot/bazel-out/darwin_arm64-fastbuild/jupyter.runfiles/python3_aarch64-apple-darwin/bin/python3` and the output of `!python --version` is `Python 3.11.4`.

The current click module is version `8.1.7` and upgrading it did not help nor did downgrading it to version `8.0.4`.

Protobuf is showing as installed with version `3.20.3`. Thanks very much for any insight you may have.

hey @ht99, have you tried setting `WANDB__EXECUTABLE` to your Python’s path? Additionally, do you reach this error when trying to login to wandb outside of a bazel server (and preferably in a fresh environment)? Would it also be possible to run `!pip install protobuf` explicitly before importing wandb and logging in?

Please let me know how any of the above suggestions go

Hi Hailey, since we have not heard back from you we are going to close this request. If you would like to re-open the conversation, please let us know!

Thanks for your suggestions @uma-wandb and sorry for the delay in response; I’ve just found time to debug this again. I’ve tried the following from within the bazel server:

```auto
os.environ['WANDB__EXECUTABLE']=sys.executable

```

I still get the same error message. I’ve also made sure that protobuf is installed explicitly.  
I do not reach this error when logging into wandb outside of a bazel server in a conda env. Here are the differences in package versions between bazel and the working conda server:

> Bazel:  
> Python version==3.10.9  
> Protobuf==3.20.3  
> wandb==0.16.2

> Conda:  
> Python version==3.11.7  
> Protobuf==3.17.2  
> wandb==0.16.2

Hi, I am facing a similar issue. I tried login but it gives me the sys.executable not correct error.
