I am having a problem that I think is related to this commit. Subnet 11, using this version, is failing to start with the following:

KeyFileError: Keyfile at: /root/~/.bittensor/wallets/redacted/hotkeys/redacted does not exist.

Note the ~ in the path.

If I set the environment variable BT_WALLET_PATH then it works.

I was able to use the latest version bittensor-wallet 2.1.1.

Please provide more context to help me understand what I missed.
Thank you for your comment.

Thanks so much for the reply!

I encountered this while working on subnet 11, which was upgraded yesterday. This is happening in the Validator class, roughly here: https://github.com/impel-intelligence/dippy-bittensor-subnet/blob/main/neurons/validator.py#L228.

I think it's related to the Config method vs WalletConfig, specifically where the Config method prepends the ~ (https://github.com/opentensor/btwallet/blob/main/src/config.rs#L42).

In terms of reproducibility:

>>> from bittensor_wallet import Wallet
>>> w = Wallet()
>>> w.config()
Config(name: 'default', path: '~/~/.bittensor/wallets/', hotkey: 'default')

If the code from SN11 isn't correct let me know and I'll reach out to them.

Thanks!

For sure. Anytime you can ask any questions. Pls feel free to do it.

And, I got you. Yep, I found this bug and fixed it in this PR #67

This fix will be available in the next release.
Also, to be make sure it's working for now, pls see the next code snippet based on the code with that fix:

In [1]: from bittensor_wallet import Wallet

In [2]: w = Wallet()

In [3]: w.config()
Out[3]: Config(name: 'default', path: '~/.bittensor/wallets/', hotkey: 'default')
