Python cannot find abi_ens_resolver from web3.utils.normalizers

[lancechua]

Hi,

The script fails at the line
from web3.utils.normalizers import abi_ens_resolver

I'm using Windows 10 machine with Anaconda Python 3.6.
For context, I installed the following packages from precompiled binaries

• lru_dict
• cytoolz

I installed web3 and websocket from pip.

Hope someone can help. Thanks in advance.
