Hi,
I meet a problem when I use gdal_calc.py on mac:

Dear GDAL experts,
I have a problem using *gdalwarp*.
I want to reproject a raster and change its resolution by the average
method.
This is the *gdalinfo* of the raster
[q70176a@ito-2 ~]$ gdalinfo
DP12/11_RawData/02_GGP/Gross_PP_8Days_500m_v6/GPP/MOD17A2H_GPP_2016_001.tif
Dear Gdal Developer,
Thank you for reading my email.
I used gdal.Wrap() to resample from a high resolution to a lower. However,
my raster has no value (nan). So, when I set resampleAlg, the larger grids
with nan(s) will become nan.
Here is my reprex in Python:
from osgeo import gdal
### resamp
