You are correct: the `run_experiment` function in `phoenix.client.experiments.__init__.py` does *not* take `base_url` as a direct argument in its signature (<https://github.com/Arize-ai/phoenix/blob/28d56f691a27136f0a4dc82c0efe27c6b7de1c79/packages/phoenix-client/src/phoenix/client/experiments/__init__.py#L17-L30|see here>). Instead, `base_url` is used when you instantiate a `Client`, which you can then pass to `run_experiment` via the `client` argument. The function itself only accepts `client`, not `base_url` directly.
If you want to specify a custom `base_url`, you should create a `Client` with that `base_url` and pass the client to `run_experiment`. Passing `base_url` directly to `run_experiment` will not work, as it is not a recognized parameter in the function signature (<https://github.com/Arize-ai/phoenix/blob/28d56f691a27136f0a4dc82c0efe27c6b7de1c79/packages/phoenix-client/src/phoenix/client/experiments/__init__.py#L17-L30|source>).
Would you like a code example or more detail on how to use a custom `base_url` with `run_experiment`?
