step - correct_troposphere error

[sakuya_izayoi]

I'm having trouble with a parsing error.

Please help.

I encountered the following error while performing analysis with Mintpy and I'm in need of assistance. Furthermore, I have confirmed that the analysis of the data from https://mintpy.readthedocs.io/en/latest/demo_dataset/#sentinel-1_on_western_cape_south_africa_with_snap has been completed successfully.

I will also attach the full analysis log. Please let me know if you have any information.

The environment is Ubuntu running on Docker on Windows, with Python 3.7.

When I skipped the above part, the analysis worked. 

Although atmospheric correction was not possible, I was able to grasp the situation once.

Thank you.

The importlib module, which is used by PyAPS, requires Python 3.8+. So you would need to update your python to use this option.
