Failed to load dynlib/dll 'D:\\Users\\16886\\Desktop\\molpy\\caffe2_detectron_ops.dll'.

[caiyingchun]

The code successfully works while executing using CMD , but when it is binded to *.exe file using Pyinstaller, It throws an error and stops executing (the Message is given below). I tried all possible solutions by linking the path library and other stuff too. Any tries failed, although the file caffe2_detectron_ops.dll was included in the right folder.
OS system: win10
Python 3.7
Pyinstaller3.6
Pytorch1.5.0

Who can help me? Thanks very much.

Did you ever solve this problem? I have the same problem?

[caiyingchun]

@JStuckner Yes, I solved the problem. inter-openmp is needed by pytorch.
You can check pytorch/pytorch#35803
pip install intel-openmp
After installing this library, copy libiomp5md.dll, libiomp5md.pdb, and libiompstubs5md.dll from ../Library/bin to your *.exe folder. It will work.

I solved this problem by:

1. Conda uninstall torch, torchvision and relatings. I used conda to install torch as guided by pytorch.com
2. Using pip to install torch, torchvision.

It works. The solution provided by Anaconda doesn't work at all. Just refuse conda.
