openseespymac ImportError: opensees.so image not found

[tomvanmele]

hi,

was trying out the Python bindings for opensees for mac but ran into an ImportError.

Traceback (most recent call last):
  File "/Users/vanmelet/Code/compas_fem/examples/opensees/ElasticTruss.py", line 1, in <module>
    from openseespymac.opensees import *
ImportError: dlopen(/Users/vanmelet/anaconda3/envs/fem/lib/python3.7/site-packages/openseespymac/opensees.so, 2): Library not loaded: /usr/local/opt/python/Frameworks/Python.framework/Versions/3.7/Python
  Referenced from: /Users/vanmelet/anaconda3/envs/fem/lib/python3.7/site-packages/openseespymac/opensees.so
  Reason: image not found

would you have any advice on how to solve this?

thanks!

same problem on windows. however on linux it works...

[zhuminjie]

For mac version, you need install with

pip install openseespymac

[tomvanmele]

i know. that is what i did

[tomvanmele]

the .so is present in the package, but it cannot be found/loaded...

[zhuminjie]

I am not familiar mac. Can you contact the author of the mac version

https://pypi.org/project/openseespymac/

[tomvanmele]

okay will do.

but just for your information, the same thing happens on windows with the pip install for windows.

everything works fine on linux though...

[zhuminjie]

It should not happen with windows. Do you have multiple versions of Python installed on Windows?

[tomvanmele]

no i installed it in a separate conda environment.
and i have not other python installed on my system...

conda create -n test python=3.7
conda activate test
pip install openseespy
python
>>> from openseespy.opensees import *

[zhuminjie]

I did a fresh install and everything seems okay to me

[tomvanmele]

hmm okay will try again. but the conda based install should be okay right?

[zhuminjie]

You can use pip install in a conda environment.

[tomvanmele]

weird, keeps failing for me.

[tomvanmele]

python version in your environment?

[zhuminjie]

Try

import openseespy
print(openseespy.__file__)

it gives the installation location, then go to openseespy/opensees/win/ to check if opensees.pyd is there.

[tomvanmele]

yup it is there

[zhuminjie]

I used the exact python version as yours

[tomvanmele]

okay, again, weird :)
are the bindings generated through pybind?

[zhuminjie]

No
