After annotations and starting train, I'll get the following error. Is this solvable trivially by initializing differently?

[nirmalya8]

Can I have a look at the code? As far as I can debug by seeing the error, weights is of type numpy.ndarray. To call weights, try weights = self.weights (Without the brackets as it isn't a function). This should work, otherwise have to look at the code.

Oops, that's a typo - thanks for catching that!

I've pushed version 0.26.4 with the fix to pypi - you can update DAS with pip install DAS --update --no-deps. The new version should be available via conda/mamba in an hour or so.

thx!
