Build errors on Manjaro Linux

[unfa]

Hi! I'm running Manajro, and I'm tring to install butterflow using the instructions provided here.

I've installed opencv2 from AUR, and this is where I'm at:

What am I doing wrong?

#101

also use command python2 instead of python. Good luck 😄

but then the best youll get is an error:

[snip@KDesktop butterflow]$ butterflow -h Traceback (most recent call last): File "/usr/bin/butterflow", line 11, in <module> load_entry_point('butterflow==0.2.4a4', 'console_scripts', 'butterflow')() File "/usr/lib/python2.7/site-packages/pkg_resources/__init__.py", line 489, in load_entry_point return get_distribution(dist).load_entry_point(group, name) File "/usr/lib/python2.7/site-packages/pkg_resources/__init__.py", line 2852, in load_entry_point return ep.load() File "/usr/lib/python2.7/site-packages/pkg_resources/__init__.py", line 2443, in load return self.resolve() File "/usr/lib/python2.7/site-packages/pkg_resources/__init__.py", line 2449, in resolve module = __import__(self.module_name, fromlist=['__name__'], level=0) File "build/bdist.linux-x86_64/egg/butterflow/__init__.py", line 6, in <module> ImportError: No module named _winreg

sad. I was really hoping for something like this to work.

Try using ffmpeg -i source.mp4 -filter:v minterpolate -r 120 result.mp4! Im not sure how to speed it up but it essentially does the same thing as this.

sudo ln -s /usr/lib/python2.7/site-packages/numpy/core/include/numpy/ /usr/include/numpy
