pyinstaller EXE OSError: could not find or load spatialindex_c-64.dll

Question

I am using Window 10 64bit to create exe. However, the exe gives error below: File "rtree\core.py", line 126, in OSError: could not find or load spatialindex_c-64.dll [23324] Failed to execute script microwave_python_code

I tried below solutions ppl shared but still cannot solve the problem.

1. --add-data=C:\path\to\spatialindex_c-64.dll;. to my build command
2. pip uninstall rtree then install using 'Rtree-0.9.4-cp37-none-win_amd64.whl'
3. install 'spatialindex-src-1.9.3.tar.gz'
4. copied the 'spatialindex_c-64.dll' into rtee site package folder
5. copied the 'spatialindex_c-64.dll' into exe folder

Anyone able to create working exe by doing above? I still face problem after trying above solutions. Anything else that I can do to get my exe works?

Answer 1

I had the same issue, and I solved it using the final answer on http://pyinstaller.47505.x6.nabble.com/OSError-while-running-exe-td2997.html.

To solve it, find the .specs file that is made when building the .exe, and add two things to it:

from PyInstaller.utils.hooks import collect_dynamic_libs
...
a = Analysis(...
            binaries=collect_dynamic_libs("rtree"),
            ...)

That will find the .dll files used by rtree. After that, you can rebuild it with the command pyinstaller your_script_name.spec.
