2 years ago Appears the dep-solver gave you ancient versions of a number of packages in order to get matplotlib=3.5, perhaps some that have broken requirements. perhaps a simple immediate workaround is to install with matplotlib=3.4 ?

2 years ago We should debug this further and move these ancient packages to the broken label. Also, something is odd with mpl, that should not happen. I'm away for a few days but I can try to do this when I get back.

2 years ago @ocefpaf I believe one of the issues is a lack of icu69 + qt , so the dep solver is going way back in time. Another alternative here is to use the matplotlib-base package, so to avoid qt. For me, this pulls in a valid fiona build.

2 years ago We see a similar error on geoviews CI but only for Python 3.8/MacOs:

Yeah, and those old packages should probably be marked as broken due to bad pins. The problem is how to properly identify them.

2 years ago @ocefpaf, so in the original example, we have libgal 3.0.2 h7c14f60_1, which isn't a conda-forge package!
@mwtoews , your conda info does not appear to show the conda-forge channel as an option. Additionally, do you have channel priority set to strict?

Ah! Good to know!! I tried my best to remove as many broken pkgs as I could in the past and I thought I missed one.

2 years ago It seems that conda-forge was not added to the environment, which is why gdal was taken from pkgs/main. This is a bit of a surprise to me, as I assumed that the options passed to conda create e.g. -c / --channel would apply to the new environment, and dependencies like gdal.
Adding --strict-channel-priority to the initial command shown in this issue installs everything from conda-forge and fixes the import error. Is there a better "fix"? Otherwise this issue can be resolved as a "user error".

2 years ago Passing a channel on the commandline does NOT persist it. You have to manually add it to either your user config (conda config default) or your environment config (conda config --env).

As of a few days ago, fiona cannot be installed with matplotlib.
Note there are several other issues here attributed to libpoppler.
