What was wrong?

Seeing

python3.10/site-packages/eth_abi/codec.py:87: DeprecationWarning:
  
  abi.encode_abi() and abi.encode_abi_packed() are deprecated and will be removed in version 4.0.0 in favor of abi.encode() and abi.encode_packed(), respectively

when using Web3.py.

This is an internal to Web3.py

This is an annoyance, which prevents running any tests with pytest -Werror.

How can it be fixed?

I do not know, because I do not know how web3.py and dependency package releases are co-ordinated.
