reinstall ta-lib with the latest numpy. This has nothing to do with ta.

ta is not ta-lib (which imports as talib) - but it's the ta library.
That's a dependency freqtrade does not depend on - so it's up to the user to make sure to install it if he want's to use it.

I installed it and unless I'm mistaken it has a compatibility issue which would make all the strats that use it currently unusable ... I've included the error log.
