2019/09/10 21:36:10 WARNING <module>(39) Could not include fastecdsa library, using slower ecdsa instead

[tycooperaow]

On creation of a new wallet:
w = HDWallet.create('Wallet1')
I received this error from the module.
2019/09/10 21:36:10 WARNING (39) Could not include fastecdsa library, using slower ecdsa instead.
Any clue as to what it means and what I can do to fix it?

You can try to install the fastecdsa library seperately and see if that works or if any error pops up.
But you can ignore this warning if you are not using BIP38 encrypted keys, the speed of the library is not affected.
What OS are you using? Because I know fastecdsa and Windows is problematic.

Same here, using Windows.
