Tryed to use downloaded ecmwf open data as input from here: https://www.ecmwf.int/en/forecasts/datasets/open-data using file ....12z/ifs/0p25/oper/20241204120000-0h-oper-fc.grib2 in an try to get a little bit fresher input than almost 1.5 day old what --input ecmwf-open-data provided and it eneded in following error when tryed to run panguweather:
ValueError: cannot reshape array of size 53988480 into shape (5,13,721,1440)

Confirmed with wgrib2 that the file is 721x1440 and still ai-models trows error
