TypeError: initial_value must be unicode or None, not str

[Goro2030]

When running a very basic test, like this:

from bitcoinlib.services.services import *
from bitcoinlib.services.bitcoind import *
from pprint import pprint


from bitcoinlib.services.bitcoind import BitcoindClient
bdc = BitcoindClient.from_config('/home/user00/.bitcoin/bitcoin.conf')

# Check bitcoind connection
pprint(bdc.proxy.getnetworkinfo())

# Get latest block
latest_block_hash = bdc.proxy.getbestblockhash()
print("Getting latest block with hash %s" % latest_block_hash)
latest_block = bdc.proxy.getblock(latest_block_hash)
transactions = latest_block['tx']
print("Found %d transactions" % len(transactions))

I get the error:

python blockchain_parse.py
Traceback (most recent call last):
  File "blockchain_parse.py", line 7, in <module>
    bdc = BitcoindClient.from_config('/home/chile00/.bitcoin/bitcoin.conf')

    config.read_string(config_string)
  File "/usr/lib/python2.7/dist-packages/backports/configparser/__init__.py", line 722, in read_string
    sfile = io.StringIO(string)
TypeError: initial_value must be unicode or None, not str

Python is 3.7 . Running on Ubuntu kernel version 4.18.0.25

The configparser module is complaining about the encoding of the configfile which should be unicode apparently. So maybe you can try to convert the format of the config file.

You can also avoid this issue by adding the connection setting to the .bitcoinlib/config/providers.json config file:
"bitcoind.testnet": { "provider": "bitcoind", "network": "testnet", "client_class": "BitcoindClient", "url": "http://user:password@server_url:18332", "api_key": "", "priority": 11, "denominator": 100000000 }

Thanks! I figured it out that the lib has to be run with Python 3, not 2.7 .... that solved it too
