test demo.py with https://github.com/justanhduc/pyPyrTools/tree/test-branch, got error

wrapConv.so: invalid ELF header

then rying to compile the library locally:
gcc -shared -L/usr/lib/python2.7/ -I/usr/lib/python2.7/include/ -lpython2.7 -o wrapConv.so -fPIC convolve.c edges.c wrap.c internal_pointOp.c
error:
/tmp/ccmZ6hfE.o: In function internal_pointop': internal_pointOp.c:(.text+0x0): multiple definition of internal_pointop'
/tmp/ccLrDosE.o:wrap.c:(.text+0x11f7): first defined here
collect2: error: ld returned 1 exit sta

found older version wrap.c from https://github.com/LabForComputationalVision/matlabPyrTools/blob/master/MEX/wrap.c.

Successful compiled library locally.

I found no attribute named bandIndex

index_lo = pyramid.bandIndex(level + 1, band)
index_hi = pyramid.bandIndex(level, band)
index_lo = pyramid.bandIndex(level, band)

Thanks in Advance

Got this error when I execute demo.py

I installed all the packages needed to make the project run

Traceback (most recent call last): File "demo.py", line 40, in <module> new_frames = interpolate_frame(img1, img2, n_frames=args.n_frames, scale=.5**.25, xp=xp) File "/home/adrien/Bureau/Phase-based-Frame-Interpolation/frame_interp.py", line 149, in interpolate_frame phase_diff = compute_phase_difference(L, R, scale, limit) File "/home/adrien/Bureau/Phase-based-Frame-Interpolation/frame_interp.py", line 21, in compute_phase_difference xp = L['pyramids'][0].xp AttributeError: SCFpyr instance has no attribute 'xp'

Can anyone help me ?

Can you please provide a code which supports a cpu without cuda.
