Fiona: Ubuntu12 Python2.7 Anaconda2-4.1 Fiona1.7 listlayers() ValueError: OGR/GPX driver has not been built with read support

When I’m trying to load GPX-file using python module Fiona appears error ValueError: OGR/GPX driver has not been built with read support. Expat library required

in python

>>> fname='/home/o/jp/run.gpx'
>>> import fiona
>>> fiona.listlayers(fname)

 ERROR 6: OGR/GPX driver has not been built with read support. Expat library required
 Traceback (most recent call last):

 ValueError: OGR/GPX driver has not been built with read support. Expat library required

see using fiona for loading GPX-files https://ocefpaf.github.io/python4oceanographers/blog/2015/08/03/fiona_gpx/

Fiona uses GDAL https://pypi.python.org/pypi/GDAL/

I have build and install it from sourses according https://trac.osgeo.org/gdal/wiki/BuildingOnUnix ./configure --prefix=/media/disk2/gdal/

>>> fiona.__version__
'1.7.0.post2'

gdal-config --version =2.1.0

How can I fix it?

May I ask you for advice - where can I make a question about solving this problem? @rbuffat has been asking you questions in order to make sure that the problem isn’t with your installation.

If this can be reproduced on another machine, someone could figure out if it a bug in GDAL, Fiona, or the installation itself. A small upload of a GPX file would be helpful. (I probably haven’t used GPX format in 3 or more years.)

Another installation test, does this print some info about successfully opening the GPX file or give an Expat error?

$  ogrinfo run.gpx

What is the output of ogr2ogr --formats?

“OGR/GPX driver has not been built with read support. Expat library required” is to my knowledge an error message from gdal not from fiona. As fiona points to the correct gdal installation the problem should be with your gdal installation.

Regarding Gdal 2.1, I do not know of any issues:

fiona.__gdal_version__ not fiona.gdal_version

Can you check if:

you can open the file with gdalinfo of your gdal installation. (check gdalinfo --version)
You installed fiona for the gdal version you have compiled:

>>> import fiona
>>> fiona.__gdal_version__
'1.11.3'

I suspect you are missing the libexpat-dev package. If you have installed the libexpat manually you need to ensure that it is in the LD_LIBRARY_PATH.

This is not an issue of Fiona. The gdal you have installed has the support for the expat library not compiled in.

Maybe the gdal version of the ubuntugis ppa has expat support: https://launchpad.net/~ubuntugis Otherwise you can compile gdal with expat enabled on your own from the source code: http://trac.osgeo.org/gdal/wiki/BuildingOnUnix

Edit: I just saw that you compile from source. Do you have the libexpat-dev package installed. When you execute ./configure to install gdal you should see if the support for expat is enabled or not.
