i'm using OSGeo4W64 (gdal 2.0.2-8) with Python 2.7.5 on Windows 8.1 64bit. Editor is PyCharm 2016.1.2.

I want to save an image with gdal, but i always get an error when the python script is complete. The following example causes the error:

from osgeo import gdal
import numpy as np

path = 'D:\\test.tiff'
data = np.array([[1]])   
sizeY = int(data.shape[0])
sizeX = int(data.shape[1])
bandCount = 1
driver = gdal.GetDriverByName("GTiff")

dataSet = driver.Create(path, sizeX, sizeY, bandCount, gdal.GDT_Byte)
band = dataSet.GetRasterBand(1)
band.WriteArray(data)  # causes error, if commented out, everything is fine

band = None
dataSet = None

print "the appcrash will come next"

I'm dereferencing the vars and it should be fine, but i'm getting "python.exe has stopped working".

The console shows:

the appcrash will come next

Process finished with exit code -1073741819 (0xC0000005)

When i run the code in QGIS (2.14.1) and i close QGIS, a similar error occurrs and a dump file was created.

Process Name:   qgis-bin.exe : C:\OSGeo4W64\bin\qgis-bin.exe
Process Architecture:   x64
Exception Code: 0xC0000005
Exception Information:  The thread tried to read from or write to a virtual 
address for which it does not have the appropriate access.

My GDAL-Enviroment-Vars are:


I have no idea why this error happens (maybe something with the dereferencing). The error might be similar to here.

  • The script makes no sense. You can print the values of data, sizeY and sizeX. It will see why.

  • It's just a test setup, which creates a pixel with the value of 1. Data can be any grayscale image data.

I had such problems with not only python gdal binds but with standard gdal apps: gdalwarp, gdal_translate and so on.. So the problem was solved after full reinstall of all gdal and python reminds in system with refreshing path and gdalpath enviroment vars. The fastest way:

  1. Install Anaconda https://www.continuum.io/downloads,
  2. Install GDAL core from gisinternal http://www.gisinternals.com/release.php with refreshing env vars
  3. From Anaconda direcory execute "conda install gdal"
