I had also some troubles when i installed fiona and tried to import it. I had this kind of message

>>> import fiona
Traceback (most recent call last):
  File "<stdin>", line 1, in <module>
  File "D:\Software\Ingenieria\Anaconda2\lib\site-packages\fiona\__init__.py", l

 line 9, in <module>
    from fiona.ogrext import Iterator, ItemsIterator, KeysIterator

How did it work for me at the end?

I installed the distributions GDAL 2.2.4 and Fiona from this link
Then i checked if my computer has a c++ compiler for python (here link with some information about which one you may need to install). In some forum questions i read that GDAL need this compiler to be able to work.
Then i added the Osgeo folder path (there are the dlls for fiona) to my path environment variable, some pics from my pc Print screen 1 Print screen 2

After doing those steps i never had any more problems with fiona. At first, i was using the GDAL version 1.1.4 but it never worked with this one. You can try first with the version one, and if it doesn´t work then install the version 2.2.4

回答2:

Maybe is better to mention that GDAL 2.2.4 is for Python 2.7 (as in the link provided).

I was having the same ImportError issue with Python 3.7, Fiona 1.8.6 and GDAL 3.0.0

By replacing GDAL 3.0.0 with 2.2.4 I got it working, without consideration of the other details

回答3:

You are missing DLLs for either OGR, GDAL, or both. Your post is scant on details such as operating system, etc so the best I can do is refer you to the installation instructions:

http://toblerity.org/fiona/README.html#installation

Also, I noticed you seem to be using Python 3.6. To quote the instructions:

"Fiona requires Python 2.6, 2.7, 3.3, or 3.4 and GDAL/OGR 1.8+."

That could be a potential issue as well.
