sudo: ./src/build-docker.sh command not found

I am trying to run my model inferencing scripts using the following code:

```
ez=ezsmdeploy.Deploy(model="best_model",
script="inference_script.py",
requirements=["thirdai==0.4.1","boto3"],
wait=True,
instance_type="local")
```

I am getting the error
`sudo: ./src/build-docker.sh: command not found`

but on inspecting the docker folder (src folder), I can see that there is a `build-docker.sh` present there. But if I run the above line repeatedly, the error goes away and docker containers are built.

This is probably an issue with checking the existence of `build-docker.sh` file.
