#656: Missing DLL when importing Fiona, Geopandas or rasterio within QGIS
----------------------+-------------------------------------

    Type:  defect     |     Status:  new

----------------------+-------------------------------------
 Hi,

 Since the release of **QGIS 3.16.2-Hannover** or **3.10.13-A Coruña** on
 Windows 10 I have been getting errors (see below) when trying to import
 fiona, geopandas and rasterio.

 I have installed fiona, geopandas and rasterio using the OSGeo4w.

 How do I go about fixing this issue for this release while not breaking
 older releases?

 Is there a way to configure these packages to work with QGIS without
 having to request a rebuild/fix every time a new version of QGIS is
 released?

 Thanks in Advance.
 Christina
