Dear all,

When I run this command, "unwrap_error_hybrid.py -h", an error occurs on my computer. I want to ask how to solve it. Thanks you!

/media/hzc/HDD/Iran-7.3/PySAR-Stack/FernandinaSenDT128/PYSAR$ unwrap_error_hybrid.py -h

Traceback (most recent call last):

File "/home/hzc/Software/PySAR/pysar/unwrap_error_hybrid.py", line 23, in <module>

from pysar.unwrap_error_phase_closure import run_unwrap_error_closure

ImportError: cannot import name 'run_unwrap_error_closure'

Best regards

Hi Zicheng,

unwrap_error_hybrid.py is still in development and not ready to be used yet, it will be removed from the current module in the next code update. Please use unwrap_error_bridging.py or unwrap_error_phase_closure.py instead, and don't hesitate to let me you know if you encounter any problem there.

regards,

Yunjun

Dear Yunjun

Thank you very much for your answer. But I have this problem when running troposphereic correction.

command line: tropcor_pyaps.py -f timeseries.h5 --model ECMWF -g ./INPUTS/geometryRadar.h5 -w ../WEATHER

result:

weather model: ECMWF

output tropospheric delay file: INPUTS/ECMWF.h5

weather data directory: ../WEATHER

time of cloest available product: 12:00 UTC

read date list from timeseries file: timeseries.h5

reference pixel: [76, 156]

geocoded: False

converting DEM/incAngle for PyAPS to read

converting lat for PyAPS to read

converting lon for PyAPS to read

------------------------------------------------------------------------------

downloading weather model data using PyAPS ...

number of grib files to download: 98

------------------------------------------------------------------------------

calcualting delay for each date using PyAPS (Jolivet et al., 2011; 2014) ...

convert to relative phase delay with reference date: 20141213

Traceback (most recent call last):

File "/home/hzc/Software/PySAR/pysar/tropcor_pyaps.py", line 485, in <module>

main()

File "/home/hzc/Software/PySAR/pysar/tropcor_pyaps.py", line 471, in main

get_delay_timeseries(inps, atr)

inps.ref_idx = date_list.index(inps.ref_date)

ValueError: '20141213' is not in list

If you can help me solve it, I will be very grateful!

Best regards

Hi Zicheng,

Could you check if you have successfully download the *.grb files in “../WEATHER” directory? I guess your PyAPS may not be working. If so, please check the previous post: https://groups.google.com/forum/?nomobile=true#!topic/py-sar/QlMROoVxs30

Please note that you also need an account on ECMWF to be able to download the ERA-Interim dataset, as described in Caltech’s website.

I attached the “INPUTS/ECMWF.h5” file in the example dataset, and pysarApp.py will search for it and use it directly, thus the tropospheric delay correction should work if you run pysarApp.py; while tropcor_pyaps.py calculate and re-generate it from the downloaded grib files.
