Cannot import marius

[qhtjrmin]

Hello, I installed marius on my local server, using the command 'pip3 install .'. I successfully installed it, but I cannot import marius.

If I try to import marius or run 'marius_preprocess', then I get the error below:

Traceback (most recent call last):
File "<stdin>", line 1, in <module>
File "/home/.conda/envs/marius/lib/python3.7/site-packages/marius/__init__.py", line 13, in <module>
    from . import _config as config
ImportError: /home/.conda/envs/marius/lib/python3.7/site-packages/marius/libmarius.so: undefined symbol: _ZNSt12experimental10filesystem2v16statusERKNS1_4pathE

Could I fix it and run marius??

The following is my setting:

Thanks

Thanks for surfacing this. I believe the issue here is that gcc-7 does not support the filesystem C++ header, which we use to help manage files for checkpointing.

I'll remove the dependency on this header. Until then you can try upgrading your compiler to gcc-8 or above, which should fix the issue.

I pushed a fix so things should work with gcc-7 now. Let me know if it works.

Oh, now it works well! Thanks for it.
