Could you help me to solve this problem, thank you very much

Hello,
I could process the same Landsat8 file without an error with v4.13 (which I see you are using as well).
Do you get the same error on another L8 file ? Could you post your run script ?

Hi, This is the script

from polymer.main import run_atm_corr, Level1, Level2
from polymer.level1_landsat8 import Level1_OLI
from polymer.level2_nc import Level2_NETCDF

run_atm_corr(
Level1_OLI('/media/dndat/ATC_Proc/LC08_L1TP_045011_20130813_20170309_01_T1/'),
Level2_NETCDF(outdir='/media/dndat/ATC_Proc/', ext='LC08_L1TP_045011_20130813_20170309_01_T1_polymer.nc', overwrite=True, tmpdir='/tmp/'), multiprocessing=-1
)

I did not get this error in tropical area. It happened for the scenes close to polar area
Cheers

Possibly. I can not reproduce the error.
Did you run l8_angles with :
l8_angles LC08_L1TP_045011_20130813_20170309_01_T1_ANG.txt BOTH 1 -b 1 ?

Yes, I did it
