AttributeError: 'NoneType' object has no attribute 'astype' #1031

Closed venjiehu closed 1 year ago

venjiehu commented 1 year ago

Description of the problem Hi all, 1)In step - correct_unwrap_error, I got some error message. It seems to be missing some files in the 'ifgramStack.h5'. 2) And in the previous step-Quick overview, mintpy don't generate 'numTriNonzeroIntAmbiguity.h5' file, I find some warning message. I want to know what triangles file is, and how connected between it and error.

Warning: No triangles found from ifgramStack file: /mnt/f/Luding/topstack/Process/mintpy2/inputs/ifgramStack.h5!
                       Skip calculating the number of triplets with non-zero integer ambiguity.

Full script that generated the error

System information

yunjunz commented 1 year ago

Triangles, or triplets of interferograms, are defined in equation 8 in Yunjun et al. (2019). You can find more descriptions about the phase closure unwrapping error correction methods. Based on the printout msg, your stack of interferograms has a sequential connection of 1, and could not form any triplets, therefore, you could not use phase closure for unwrapping error correction.

You could either turn off this option or generate more interferograms using a sequential connection of 2, 3 or more and re-run.
