Web3.py: Cannot import web3

[avatar-lavventura]

• pip 9.0.3
• Python: 3.5
• OS: linux (ubuntu)

### pip install:
$ sudo apt-get install python3-pip
$ sudo pip3 install virtualenv
#once
$ virtualenv -p python3 ~/.venv-py3
# each session:
$ source ~/.venv-py3/bin/activate

Current session is: (.venv-py3) user$

When I use following line on my python file:
from web3.auto import w3

I receive the following error:

Traceback (most recent call last):

What's the result of python --version while in the virtualenv?

typing.Type was introduced in version 3.5.2 according to https://docs.python.org/3/library/typing.html

[avatar-lavventura]

(.venv-py3) $ python --version
Python 3.5.0

=> Is this correct way to import web3 library: from web3.auto import w3?
=> Do I need to upgrade to 3.5.2? (I couldn't find a way to upgrade it to 3.5.2 ) @carver

Is this correct way to import web3 library: from web3.auto import w3?

Yup, as long as your node is running at one of a few common locations. Check http://web3py.readthedocs.io/en/stable/providers.html#automatic-provider-detection

Do I need to upgrade to 3.5.2? (I couldn't find a way to upgrade it to 3.5.2 )

Yes

There is a backport of the typing library you can use if needed: https://pypi.python.org/pypi/typing

I'm on python 3.7 and I am getting this error.

@redserpent7 please open a new ticket, with the full traceback, the result of python -V, and your installed libraries (pip list).
