I've done this a dozen times before, but something isn't working this time..
Following the docs:
https://docs.djangoproject.com/en/1.11/ref/contrib/gis/install/#windows
I'm trying to set up GeoDjango on a Windows machine (this one is a virtual windows 10 set up on paperspace.com). There seems to be a problem with my PATH settings, but I can't figure out what it is. I've run the commands highlighted in the instructions. I've checked my PATH variables and everything seems ok. I've tried pointing them to both the 32-bit and 64-bit versions of OSGeo4Win. Regardless, I get the following output every time:
C:\Python\lib\site-packages\floppyforms\__init__.py:21: UserWarning: Unable to import floppyforms.gis, geometry widgets not available

Does anyone have any ideas?
UPDATE: I went to the store and bought a new laptop and I am still running into the same issue. Could it be an versioning issue with some of the GeoDjango dependencies? I'm at a loss for what to do, but it's kind of an emergency for me.
The issue ended up being a version mismatch between Django and GDAL. Django was not searching for the correct file name (gdal202.dll in my case).
Fixing it required me to add str('gdal202') to the following file on line 26:
(Python Root)\Lib\site-packages\django\contrib\gis\gdal\libgdal.py
Note that if you are working in a Virtual Environment, then Python Root will actually be wherever that is ie: Users\YourName\Envs\project
If this issue reoccurs, you can look through your C:\OSGeo4W\bin directory to figure out which gdalxxx.dll it is that Django needs to search for.
In addition, make sure that you are using the 32-bit versions of Python and OSGeo4Win. Otherwise, you may see the same failure.
