using dask .compute() to load images into memory is broken by transform function

[nthndy]

I am really unsure how to fix this as im not overly familiar with the dask .compute() operation but when you try and invoke it whilst also using a transform it struggles to find individual image filenames in the list of files, mainly because it looks like its loading and reloading the list of file names multiple times for one .compute(). I am lost!

i should add that the first time it loads the list of files here it gets a list of length 0, then a correct length list, all for one .compute()
