AttributeError: 'InteractiveLoginAuthentication' object has no attribute 'get_token'

Following this notebook exactly. The only code change being changing create_or_update() to begin_create_or_update() as advised by a previous issue.

```
from azure.mgmt.network import NetworkManagementClient

# Virtual network name
vnet_name ="rl_pong_vnet"

# Default subnet
subnet_name ="default"

# The Azure subscription you are using
subscription_id=ws.subscription_id

# The resource group for the reinforcement learning cluster
resource_group=ws.resource_group

# Azure region of the resource group
location=ws.location

network_client = NetworkManagementClient(ws._auth_object, subscription_id)

async_vnet_creation = network_client.virtual_networks.begin_create_or_update(
resource_group,
vnet_name,
{
'location': location,
'address_space': {
'address_prefixes': ['10.0.0.0/16']
}
}
)

async_vnet_creation.wait()
print("Virtual network created successfully: ", async_vnet_creation.result())
```

I get result:

```

```

The failing entry point is the notebook cell that constructs NetworkManagementClient with ws._auth_object and calls virtual_networks.begin_create_or_update. Start by checking the credential type expected by the Azure pipeline versus the object supplied by the notebook; done means the cell completes without AttributeError and creates the virtual network.
