Mintpy Ver 1.5.1: KeyERROR "StartingRANGE" still persists.

[lincoln-olayta]

Hi, I've recently installed mintpy to process results from stacking using ISCE for Sentinel-1.

I've installed the MintPy using conda (conda install -c conda-forge mintpy) in a new environment (without any isce), and I've tried running an initially using "smallbaselineApp.py smallbaselineApp.cfg --dostep load_data"

Right away, I've encountered an error very similar to the reported closed issue #927.
Here's the error:

KeyError: 'STARTING_RANGE'

The numpy version that was installed was 1.24.2.

The error is very similar to the tagged issue, and I can't try to install a downgraded version since my libgcc that was installed in my terminal is for a more recent version of python (as a suggested fix).

While I try to find a way to troubleshoot this without downgrading to python=3.8, I'd like to report that this issue still persist. Thank you!

System information

• Operating system: Ubuntu-20.04_WSL
• Python environment: Miniconda (latest), Python 3.11
• MintPy version: 1.5.1 (conda version)

I can confirm that the error persists. I tried with different combinations of isce2/mintpy and numpy/python and I get the error.

It seems that prep_isce.py is having errors.

Could you try 1) install the latest development version of mintpy (instruction) and 2) install mintpy and isce2 in the same conda environment?

If the error still persists, could you let me know the following version info, so I could try to re-produce?

• python
• numpy
• scipy
• isce2
• mintpy

Hi Dr. Yunjun,

I have tried your suggestions, installing mintpy as development (using conda install -c conda-forge --file requirements.txt to install dependencies), and I've also installed isce2 in the same environment (using conda installation) and it works.

Here's the list of the packages & their versions I've installed:
isce2 = 2.6.2
python = 3.11
numpy = 1.24.2
scipy = 1.10.1
mintpy = development version (1.5.1)

I'm closing the thread. Thank you so much for your help!!
