I’m getting the following error when calling use\_artifact(). Creating an artifact seems to work fine. ```auto wandb: ERROR Error while calling W&B API: failed to find run artifact/4e54ygf8 () Traceback (most recent call last): File "/Users/yoohee/opt/anaconda3/envs/base-python39-wandb/lib/python3.9/site-packages/wandb/sdk/lib/retry.py", line 131, in __call__ result = self._call_fn(*args, **kwargs) File "/Users/yoohee/opt/anaconda3/envs/base-python39-wandb/lib/python3.9/site-packages/wandb/sdk/internal/internal_api.py", line 366, in execute return self.client.execute(*args, **kwargs) # type: ignore File "/Users/yoohee/opt/anaconda3/envs/base-python39-wandb/lib/python3.9/site-packages/wandb/vendor/gql-0.2.0/wandb_gql/client.py", line 52, in execute result = self._get_result(document, *args, **kwargs) File "/Users/yoohee/opt/anaconda3/envs/base-python39-wandb/lib/python3.9/site-packages/wandb/vendor/gql-0.2.0/wandb_gql/client.py", line 60, in _get_result return self.transport.execute(document, *args, **kwargs) File "/Users/yoohee/opt/anaconda3/envs/base-python39-wandb/lib/python3.9/site-packages/wandb/sdk/lib/gql_request.py", line 59, in execute request.raise_for_status() File "/Users/yoohee/opt/anaconda3/envs/base-python39-wandb/lib/python3.9/site-packages/requests/models.py", line 1021, in raise_for_status raise HTTPError(http_error_msg, response=self) requests.exceptions.HTTPError: 404 Client Error: Not Found for url: https://api.wandb.ai/graphql During handling of the above exception, another exception occurred: Traceback (most recent call last): File "/var/folders/38/db3wysd12rl46s8z6jx1ksr00000gn/T/ipykernel_31482/2024531381.py", line 13, in load_data raw_data_artifact = run.use_artifact("mnist:latest") File "/Users/yoohee/opt/anaconda3/envs/base-python39-wandb/lib/python3.9/site-packages/wandb/sdk/wandb_run.py", line 371, in wrapper_fn return func(self, *args, **kwargs) File "/Users/yoohee/opt/anaconda3/envs/base-python39-wandb/lib/python3.9/site-packages/wandb/sdk/wandb_run.py", line 361, in wrapper return func(self, *args, **kwargs) ...
