Issue with tqdm_dask and dask.persist in Phase and Correlation Computation

[Jamestony2460]

Hi, I’m trying to implement the following part of the code:

"# compute together because correlation depends on phase, and filtered phase depends on correlation.
tqdm_dask(result := dask.persist(decimator(corr), decimator(intf)), desc='Compute Phase and Correlation')"

The issue I’m facing is that the execution takes around 1.5 hours but doesn’t complete. Instead, it eventually fails with the following error:

"ValueError: The truth value of an array with more than one element is ambiguous. Use a.any() or a.all()"

It seems to be related to dask.persist and decimator(corr)/decimator(intf), but I’m unsure how to resolve it. Could you please guide me on how to fix this? Thanks in advance!

Please refer to the examples when it works. Also, you can use the functions Stack.compute_interferogram_singlelook() and Stack.compute_interferogram_multilook() if you don't want to perform the step-by-step processing and just need to build interferograms.
