title: Need help installing fiona and geopandas for python in Windows 10 - getting can't load requested DLL error
body: <p>I am trying to install fiona and geopandas for python on Windows 10 and keep running into an error "ERROR 1: Can't load requested DLL".</p>
  
  <p>I know this question is similar to other questions that have been asked, but I have followed the steps in multiple answers and tutorials and still can't seem to get this to work.</p>
  
  <p>The closest I got was using the steps outlined in this tutorial : <a href="https://geoffboeing.com/2014/09/using-geopandas-windows/" rel="nofollow noreferrer">https://geoffboeing.com/2014/09/using-geopandas-windows/</a></p>
  
  <p>and are summarized as follows:</p>
  
  <ol>
  <li><p>installed the .whl files for rtree, pyproj, shapely, gdal, geopandas, fiona from <a href="https://www.lfd.uci.edu/~gohlke/pythonlibs/" rel="nofollow noreferrer">https://www.lfd.uci.edu/~gohlke/pythonlibs/</a></p>
  
  <ul>
  <li>Rtree-0.8.3-cp37-cp37m-win_amd64.whl</li>
  <li>pyproj-2.2.1-cp37-cp37m-win_amd64.whl</li>
  <li>GDAL-3.0.0-cp37-cp37m-win_amd64.whl</li>
  <li>geopandas-0.5.0-py2.py3-none-any.whl</li>
  <li>Fiona-1.8.6-cp37-cp37m-win_amd64.whl</li>
  <li>Shapely-1.6.4.post2-cp37-cp37m-win_amd64.whl</li>
  </ul></li>
  <li><p>navigated to download folder and used pip install to install GDAL wheel</p></li>
  <li><p>added the osgeo path to my windows user Path environment variable </p></li>
  </ol>

  <ol start="4">
  <li>used pip install to install remaining wheels (geopandas last), everything installed without errors</li>
  <li>As a check, I ran <code>gdalinfo --help-general</code> and get the following output:</li>
  </ol>

  <p>This is where I get the "ERROR 1: Can't load requested DLL:" error. It says it cannot find the specified module "ogr_FileGDB.dll". The weird thing is, that .dll is actually in the location that it is looking in???</p>

  <p>Also, in python shell, when trying to import fiona or geopandas I get the following errors:</p>

  <p>This is beyond my level of troubleshooting...would really appreciate if anyone could get this thing working for me!!!!</p>
  
  <p>FYI - running Python 3.7.3, Windows 10, pip is updated.</p>
  
  <p>Lastly and potentially important (not sure how it plays in?) I already have a GDAL_DATA system variable defined, and also (maybe incorrectly?) also tried adding the osgeo path to my system path variable:</p>
