Fail in step modify_network: Axis limits cannot be NaN or Inf

Hi Yunjun,

My MintPy processing fail in early step modify_network:

ValueError: Axis limits cannot be NaN or Inf

I plotted the input files (samples are attached), nothing wrong based on visual inspection. Please could you help me on how to solve this issue?

os: linux

installation method: conda (isce2.6.3 and mintpy1.5.2 are in the same environment)

Hi Rino,

Could you 1) run smallbaselineApp.py --plot to generate the pic folder from the currently available files and 2) attach the following files here for diagnosis?

coherenceSpatialAvg.txt

pic/coherence*.png

pic/connectComponent*.png

Regards,

Yunjun

Hi Yunjun,

I found the problem, there is a nan in file coherenceSpatialAvg.txt.

Thanks for the response, really appreciate it.

Hi Rino,

I would still like to catch this issue in the code, and report a meaningful msg for future diagnosis. Could you show me here what your coherenceSpatialAvg.txt file looks like?

Hi Yunjun,

I attach the screenshot of coherenceSpatialAvg.txt file. To solve this issue, inside folder pairs produced by ISCE, I excluded all pairs that pair up with 20220927 then re-run MintPy from step load_data, it went through until the last MintPy step.

Cheers,

Rino

Hi Rino,

I am happy to hear your problem is solved. I am now able to re-produce your error as well, which should now also be caught in the code by (https://github.com/insarlab/MintPy/pull/1108).

Thank you for reporting this.

Cheers,
Yunjun
