Python 3.8 issues with yolo_cpp_dll.dll #4956

Open Greta-A opened 4 years ago

Greta-A commented 4 years ago

Since Python 3.8 updated their process on locating dll's, the darknet.py and darknet_video.py files give the error: "FileNotFoundError: Could not find module 'yolo_cpp_dll.dll' (or any of its dependencies)". I made sure that the dll is in darknet/build/darknet/x64 and it built successfully, the os just can't locate it.

How would I fix darknet.py to remedy this?

Using: Windows 10 OpenCV 4.2.0 Python 3.8 VS 2017

I had the same problem. yolo_cpp_dll.dl was successfully built in Darknet / build / Darknet / x64. darknet.py gives the error: filenotfounderror: could not find module 'yolo_cpp_dll.dll' (or any of its dependencies). I try to change other dll file's name as "yolo_cpp_dll.dll", and python can locate the file, but give the error: AttributeError: function 'network_width' not found. I also change the file name of "yolo_cpp_dll_no_gpu.dll" to " yolo_cpp_dll.dll". It works, but very slow with CPU. So I suspected CUDA and cudnn, and replaced CUDA 10.0 with CUDA 8.0, but the same problem still occurred. Using: Windows 10 OpenCV 3.4.0 Python 3.8 VS 2015 CUDA 8.0

Confirming. Rolling back to 3.7 solves the issue. darknet.exe app compiled and works perfect. darknet.py in Python3.8 venv fails with "FileNotFoundError: Could not find module 'yolo_cpp_dll.dll' (or any of its dependencies)"

@sca33 Thanks for this. I had the same issue and downgrading to 3.7 works.

When I used python3.8，I had the same problems. It works well with python3.7.

Any update on the resolution of this issue?

The newer python scripts using 'darknet.dll' seem to have the same problem. A possible solution is suggested here: https://stackoverflow.com/questions/66218956/import-darknet-filenotfounderror-could-not-find-module
