I've, unsuccessfully, tried to reproduce your issue with the following script:
-----
from osgeo import gdal
import concurrent.futures
def worker(in_f, out_f):
gdal.Unlink(out_f)
gdal.Warp(out_f, in_f, options = '-co COMPRESS=DEFLATE -co TILED=YES -ts
2048 2048')
jobs = []
for i in range(1000):
jobs.append( ['byte.tif', '/tmp/byte%d.tif' % i] )
with concurrent.futures.ThreadPoolExecutor(max_workers=8) as executor:
future_map = {executor.submit(worker, in_f, out_f): out_f for in_f, out_f
in jobs}
for future in concurrent.futures.as_completed(future_map):
out_f = future_map[future]
try:
future.result()
except Exception as exc:
print('%r generated an exception: %s' % (out_f, exc))
print('Finished ' + out_f)
ds = gdal.Open(out_f)
if ds.GetRasterBand(1).Checksum() != 58226:
print('wrong checksum for ' + out_f)
