Error setting up InVEST for batch running


I've been trying to set up a Python script for batch running using this tutorial: I got up to step 4 of "Creating Sample Python Scripts"-- opening up a Windows Powershell and running the script-- when I ran into an error that said a necessary module was missing ("ImportError: no module named osgeo"; "FullyQualifiedErrorID: NativeCommandError"). (A full screenshot of the error screen is attached to this post.)

         I don't have a lot of experience with Python, and I'm not sure what to do next. If anyone knows or has any tips on how to fix this, it would be greatly appreciated.

Other important information:
I am using Python version 3.7.7, and InVEST python build version 3.4.4. (win32.exe version). 

Thank you!

    Hi Andie, the error is related to GDAL not being installed, but InVEST is only Python 2.7 compatible at the moment. We're actively working on that, but there may not be much you can do at the moment unless you're interested in installing a 2.7 Python environment.

    Hi Andie,  Based on the exception, it looks like Python 2.7 might indeed be the active python version.  If so, it looks like the osgeo ("GDAL") package is missing.  Could you download one of the GDAL 2 packages from here: and use pip to install that file?  The file to download will be either the one labeled 'cp27-cp27m-win32' or 'cp27-cp27m-win_amd64' depending on if your python installation is 32-bit of 64-bit.

    Hopefully that'll fix the import!

    Thank you both! I switched to Python 2.7 and then installed GDAL-2.2.4-cp27-cp27m-win32.whl, and that fixed the missing module problem.

    Working on this same tutorial, I ran into a different problem when trying to run the script in Powershell. I've tried all kinds of things to fix it, but I still keep getting the same error every time. Here's the full traceback:

    I've also attached a screenshot of a list of packages that I have (using list function on Powershell). I'm using Python version 2.7.15 and the most recent build of InVEST Python. If anyone could help me with this I would greatly appreciate it.

    Hi Andie, interesting error!  Could you try installing one of the scipy packages from and see if that resolves the import issue?
