Error running download_train_visualize.py #4

Closed vanHavel closed 6 years ago

vanHavel commented 6 years ago

After creating the virtual environment and installing the requirements, I am running $ python3 -W ignore competition/download_train_visualize.py and get the error

  File "competition/download_train_visualize.py", line 5, in <module>
    from web3 import Web3, HTTPProvider, IPCProvider
  File "<path>/blockchain/danku/venv/lib/python3.6/site-packages/web3/__init__.py", line 5, in <module>
    from web3.main import Web3
  File "<path>/blockchain/danku/venv/lib/python3.6/site-packages/web3/main.py", line 6, in <module>
    from eth_utils import (
ImportError: cannot import name 'force_text'

there also seems to be a problem with 'coerce_args_to_text' from eth_utils. This is strange because I assume the right version of these libraries should get installed in the venv... Could it have something to do with using Python3 for this? The system is OS X.

You are using deprecated functions of eth_utils. Downgrading eth_utils to 0.8.1 resolves this error.

try pip install web3

@vanHavel Looks like it's an issue with populus.

Upgrading web3 should fix it: pip install --upgrade web3
