My Question

I have a desktop application in PyQt6 that uses Open3D for point cloud visualisation. I tried to bundle it to the standalone executable using PyInstaller, but it crashes when I'm trying to run it with the DLL load failed error(traceback below). It happens only when I try to run it on the Windows device that do not have C++ Build tools. So, the question is how can I create standalone executable without the additional step with the build tools installation?

As I understand, pybind requires some DLLs on the target system:

ImportError: DLL load failed while importing pybind: A dynamic link library (DLL) initialization routine failed.
[3924] Failed to execute script '__main__' due to unhandled exception!

Otherwise, can I know which DLLs are required for the Open3D? In this case I will try to include them to the bundle manually.

If it only happens on a PC without C++ Build tools it might be a missing Microsoft Visual C++ Redistributable install.

You can use Dependencies or Dependency Walker to check which DLLs open3d/cpu/pybind.cp311-win_amd64.pyd loads.

@sitic thank you, the problem was related to the VM's AVX support, I will close the issue
