Hi,

I'm trying to get polymer to run within a jupyter notebook. I'm running the following code, just trying to get Polymer to run:

Code: Select all

# import modules
from sys import argv
import argparse
from polymer.main import run_atm_corr, Level1, Level2
import os

# set path to MSI L1C directory
getdatapath = 'data_NT/raw/S2A_MSIL1C_20180312T191201_N0206_R056_T10UEU_20180312T222941.SAFE/GRANULE/L1C_T10UEU_A014210_20180312T191502/'

# run polymer
run_atm_corr(Level1(getdatapath), Level2())

After running the code, it thinks for a bit, then I get the following:

I installed wget in the conda environment, but that didn't solve the issue. I also thought it might be due to an issue installing the auxdata, which I installed using the command "make auxdata" instead of what's listed in the readme file, which is "make auxdata_all"? Any help would be very much appreciated!

Hello,

The auxiliary data are fixed files downloaded by the command "make auxdata_all".
The ancillary files are different, and are downloaded on the fly to get information about wind speed, surface pressure, etc, for the file you want to process.
Installing wget through anaconda should work - could you try restarting your terminal and confirm that you have access to the wget command in your terminal ?
Otherwise you can try installing if on the system if possible.
Lastly, an option is to use Ancillary_ERA5 instead of Ancillary (which fetches ancillary data from NASA server), because it uses another mechanism for downloading.
I hope this helps,
Cheers,
François
