I use the code bellow to query dgraph(VERSION=0.7.4) , then it fails.  
when use curl to query the same content, it’s OK.

```auto
In [1]: from pydgraph.client import DgraphClient
In [2]: pydgraph.client. __version__
Out[1]: '0.3.5'
In [3]: dg_client = DgraphClient('localhost', 8080)
In [4]: response = dg_client.query("""
        mutation
        {
            set
            {
                <alice> <name> \"Alice\" .
                <greg> <name> \"Greg\" .
                <alice> <follows> <greg> .
            }
        }
        """)

```

**The error is look like this:**

```auto
LocalError Traceback (most recent call last)

Hi @Aurora81

The python client was contributed by the community members and hasn’t been updated since. We changed to location of the proto file, that might be an issue. I will work on fixing it so that it is able to do basic mutations and queries. In the meantime you could still use the HTTP interface. See [https://docs.dgraph.io](https://docs.dgraph.io).

Thanks @pawanrawal

The performance of HTTP interface is much lower than grpc interface, can you show me how to fix the issue.  
Thanks very much!
