i want to use python GDAL to convert some rasters files but i take error in the create new tiff image and specific in the line driver= gdal.GetDriverByName('GTiff')

update :

python version 2.7 64 bit

GDAL version 2020100

os: windows

i use it and before this version and all work fine code :

inputfile = 'input.tif'
input = gdal.Open(inputfile )
inputProj = input.GetProjection()
inputTrans = input.GetGeoTransform()

referencefile = 'ref.tif'
reference = gdal.Open(referencefile )
referenceProj = reference.GetProjection()
referenceTrans = reference.GetGeoTransform()
bandreference = reference.GetRasterBand(1)
x = reference.RasterXSize
y = reference.RasterYSize

outputfile = tempfile.NamedTemporaryFile(suffix='.tif').name
driver= gdal.GetDriverByName('GTiff')
output = driver.Create(outputfile,x,y,1,bandreference.DataType)


error :

    return _gdal.GetDriverByName(*args)
TypeError: in method 'GetDriverByName', argument 1 of type 'char const *'

update 2:

that error show when i use this limes:

from __future__ import absolute_import
from __future__ import unicode_literals

but that i need it because i use python 2.7

any idea how to fix it ?


Because you imported unicode_literals, you're passing a unicode literal to GDAL which is expecting a string literal.

So, explicitly cast the 'GTiff' arg to a str.


>>> from __future__ import unicode_literals
>>> from osgeo import gdal
>>> gdal.GetDriverByName('GTiff')
Traceback (most recent call last):
  File "<stdin>", line 1, in <module>
  File "C:\Temp\conda\envs\test27\lib\site-packages\osgeo\gdal.py", line 3019, in GetDriverByName
    return _gdal.GetDriverByName(*args)
TypeError: in method 'GetDriverByName', argument 1 of type 'char const *'
>>> type('GTiff')
<type 'unicode'>
>>> gdal.GetDriverByName(str('GTiff'))
