it is probably some library version conflict in my environment.
When I installed z5py, libboost 1.77 was installed.
has anyone seen this error and has a solution?

Would suggest including enough info to explain how things were installed so someone else can reproduce. If Conda, conda list along with commands and channel used. Similar info for other install mechanisms

I removed the whole conda environment and reinstalled z5py, still got the same error. I used python 3.8 this time. These are the packages I got.

It looks like this mixing packages from defaults and conda-forge in an incompatible way. That is likely leading to these symbol loading errors. Would set strict channel priority and create a fresh environment
constantinpape commented
@jakirkham I am currently trying to build using std::filesystem instead of boost::filesystem to get rid of the boost linking all together and make z5py easier to install.
However, the build is failing, I think due to mac builds with c++14, see conda-forge/z5py-feedstock#47 (comment). Could you maybe have a look in the issue? Thanks!
jingpengw commented
@jakirkham the default you mentioned is the pypi?
So I should install all the packages from conda-forge rather than mixing with pypi?
jakirkham commented
No defaults is a different channel. If you run conda config --set show_channel_urls true, then it will show up on the lines that currently don't list a channel.
jingpengw commented
I created a fresh environment but still got the same symbol error.

My guess is that the boost version is incompatible with the one z5py was built with. In theory conda-forge should pin the correct version, but maybe this fails here?
I am trying to update the conda-forge build to use std::filesystem, so that linking to boost is not necessary any longer in conda-forge/z5py-feedstock#47.
However, the build fails, despite working in the CI in this repository. Any help there would be highly appreciated.
constantinpape commented
@jingpengw there is a z5py version available on conda-forge now that does not rely on boost.
Could you try installing z5py>=2.0.11 and see if that fixes the issue?
jingpengw commented
can not find this version.

It's listed here: https://anaconda.org/conda-forge/z5py/files. But was only added ~ 30 minutes ago.
It sometimes takes a while for new packages to become available fully (not sure why, maybe some caches need to be updated). Could you please try again tomorrow or next week and report back?

conda-forge mirrors packages to a CDN (hence the delay)
