Cannot use `build_local` on 'AzureML-TensorFlow-2.0-GPU' environment

In azureml-sdk version 1.0.79, when I try to run the following code:

```python
from azureml.core import Workspace, Environment

ws = Workspace.from_config()

tf_env = Environment.get(ws, 'AzureML-TensorFlow-2.0-GPU')
tf_env.build_local(ws)
```

I get this error:
```
