title: Geo Django GDAL Exception OGR Failure
body: <p>I'm using geo django and running on windows. I do have GDAL and OSGEOS configured in the settings. </p>
  
  <p><strong>Here is my settings.py code for gdal.</strong></p>
  
  <pre><code>   import os
      if os.name == 'nt':
          import platform
          OSGEO4W = r"C:\OSGeo4W"
          if '64' in platform.architecture()[0]:
              OSGEO4W += "64"
          assert os.path.isdir(OSGEO4W), "Directory does not exist: " + OSGEO4W
          os.environ['OSGEO4W_ROOT'] = OSGEO4W
          os.environ['GDAL_DATA'] = OSGEO4W + r"\share\gdal"
          os.environ['PROJ_LIB'] = OSGEO4W + r"\share\proj"
          os.environ['PATH'] = OSGEO4W + r"\bin;" + os.environ['PATH']
  </code></pre>
  
  <p><strong>I have a model that has a pointfield.
  model:</strong></p>
  
  <pre><code>class Event(models.Model):
      user = models.ForeignKey(User, on_delete=models.SET, blank=True)
      name = models.CharField(max_length=100)
      category = models.ForeignKey(Category, on_delete=models.CASCADE)
      location = models.PointField(srid=4326, blank=True)
  </code></pre>
  
  <p><strong>Whenever I try to create an event and set the pointfield value, I get this error:</strong> </p>
  
  <pre><code>GDAL_ERROR 6: b'Unable to load PROJ.4 library (proj.dll), creation of\nOGRCoordin
  ateTransformation failed.'
  Error transforming geometry from srid '4326' to srid '3857' (OGR failure.)
  </code></pre>
  
  <p>This problem seems to be a windows only issue. When I run this application on ubuntu on my virtualbox, everything seems to work fine. </p>
