Installation fails

OS: Ubuntu 16.04
Notes: I used python setup.py clean as it worked a few weeks ago. Though now it does not work.

Hi,

1. Can you delete the darknet folder in /tmp of your system. Afterwards, get a new clone of the project and try again.

2. Also can I know the exact commands you typed for installation?

(The line skipping 'pydarknet.cpp' Cython extension (up-to-date) suggests that installation is using some of the old files from a previous installation)

Thanks,

1. One way to install.
   python setup.py clean
   python setup.py install

2. Another way to install.
   pip install yolo34py-gpu

Both installations give the same error.

Hi,
Did you manage to find any solution for this issue?

It seems the reason for the issue is skipping of building of Cython extensions ( as explained by skipping 'pydarknet.cpp' Cython extension (up-to-date)) but that could happen only if a previously built pydarknet.cpp is left in the source code. If such a file exist, can you delete it and re-run the installation?

Closing due to absence of response.
