Passing generator to NumPy vstack warning

[cybersea]

When trying to run the following line in the raster notebook

listings['brightness_rasterio'] = numpy.vstack(brightnesses)

I received this warning:

FutureWarning: arrays to stack must be passed as a "sequence" type such as list or tuple. Support for non-sequence iterables such as generators is deprecated as of NumPy 1.16 and will raise an error in the future.

Would the solution be to convert the generator to a list?

This is an extremely useful resource. Thanks so much for making it available!

I think the best solution of this problem is as follow.

listings['brightness_rasterio'] = numpy.vstack([brightnesses])

or

listings['brightness_rasterio'] = numpy.vstack(list(brightnesses))
