Pyinstaller - GDAL call from os.system (gdal_translate)

Question

Greetings, I recognized the fellows. Running 32-bit Python2.7 on Windows 7.

I have a question regarding the inclusion of GDAL executables in the pyinstaller assembly. I am making a system call to run two GDAL functions from the FWTools release. These functions are located in the PATH variable in the windows C:\Program Files (x86)\FWTools2.4.7\bin , and therefore it works fine in the Python27 environment. However, this path does not migrate to the pyinstaller assembly.

This code calls the GDAL function to re-translate the image to different geospatial coordinates.

 os.system("gdal_translate -of GTiff -a_ullr 694440.7939 6403967.2406 696438.7261 6404791.6774 -a_srs EPSG:28355 site.tif siteGR.tif") os.system("gdalinfo siteGR.tif") 

Runtime works well until it falls into the above lines, and then returns the following error:

 'gdal_translate' is not recognized as an internal or external command, operable program or batch file. 'gdalinfo' is not recognized as an internal or external command, operable program or batch file. 

I tried to include both gdal_translate.exe and gdalinfo.exe in the build folder as binaries, just as you would with .dll, but since it does not work after the script started working, I think this applies to them.

I have included the specification file below. I could use some tips on how to get the pyinstaller assembly to recognize executable files running from the system in a python script.

Answer 1

From GDAL 2.1, you can use the "liberated" version of gdal_translate in python bindings, which can be more reliable and prevent you from guessing using the path:

 import gdal gdal.Translate(<options>) 

Some examples of its use can be found in the gdal repository test suite: https://svn.osgeo.org/gdal/trunk/autotest/utilities/test_gdal_translate_lib.py

You can pip install gdal and I believe this is release 2.1 (on Linux). For windows, the easiest installation method is conda .

This should prevent you from getting confused, including too many binaries / paths in pyinstaller, as this can be considered like any python module
