Error when importing pyflann in python.

I installed pyflann [on Ubuntu 16.04 python 2.7] using pip but when import pyflann in python, I get the following error:

import pyflann

ImportError: Cannot load dynamic library. Did you compile FLANN?

It is the same for me. The ~/.local/lib/python2.7/site-packages/pyflann/lib/linux/libflann.so is 0 bytes long. I have also downloaded the package from the the Python Package Index manually but the mentioned so file is 0 bytes there too. It seems that this package version is broken on Linux. Please fix the package.

I have been recompiled the pyflann/lib/linux/libflann.so file, and it works on linux now in my test. Please try again. Thanks very much for your correction.
