Error while importing Geopandas

I have installed geopandas using !pip install geopandas. Before installing geopandas I installed gdal and fiona using the same method. But while importing geopandas, following error appears always. How do I rectify it ?

AttributeError: partially initialized module 'fiona' has no attribute '_loading' (most likely due to a circular import)

OK, I can reproduce this by using the environment.yml file from movingpandas, and recreating that environment locally.

But, it seems this is actually an issue with the fiona install, because importing it on itself gives the following error (at least this is the issue for me locally, not 100% sure it’s the same issue on CI):

>>> import fiona
Traceback (most recent call last):
  File "<stdin>", line 1, in <module>
  File "/home/joris/miniconda3/envs/movingpandas/lib/python3.7/site-packages/fiona/__init__.py", line 86, in <module>
    from fiona.collection import BytesCollection, Collection
  File "/home/joris/miniconda3/envs/movingpandas/lib/python3.7/site-packages/fiona/collection.py", line 11, in <module>
    from fiona.ogrext import Iterator, ItemsIterator, KeysIterator
ImportError: libdeflate.so.0: cannot open shared object file: No such file or directory
>>> import geopandas

But, so we are masking this import error message at the moment, and letting geopandas’ import fail because of fiona’s import error (which we don’t want to do, since it’s an optional dependency now).

It seems that https://github.com/geopandas/geopandas/pull/2112 might fix this specific issue (in case that fiona’s install is actually broken)

Glad to report that Travis is happy again: https://app.travis-ci.com/github/anitagraser/movingpandas/builds/238483202
