I have installed the AutoML Tao Toolkit API using the bare metal setup instructions from the documentation. I am trying to run the classification notebook from here for running AutoML experiments.
tao-getting-started_v5.2.0/notebooks/tao_api_starter_kit/api/classification.ipynb
While executing the below cell
# Exchange NGC_API_KEY for JWT
data = json.dumps({"ngc_api_key": ngc_api_key})
response = requests.post(f"{host_url}/api/v1/login", data=data)
assert response.status_code in (200, 201)
assert "user_id" in response.json().keys()
user_id = response.json()["user_id"]
print("User ID",user_id)
assert "token" in response.json().keys()
token = response.json()["token"]
print("JWT",token)
# Set base URL
base_url = f"{host_url}/api/v1/user/{user_id}"
print("API Calls will be forwarded to",base_url)
headers = {"Authorization": f"Bearer {token}"}
I am getting the following error

I tried to run the below command by following this thread
$ kubectl edit services tao-toolkit-api-service
but i get the below error
Unable to connect to the server: dial tcp 172.x.x.x:6443: i/o timeout
Would really appreciate any help regarding this issue. Thanks.
