btk on Python 3.x

[Danylo Ulianych]

Hello. Is there any way to install BTK module on Python 3.x?

In Biomechanical ToolKit Building instructions page I found that "Python 3.0 or later is not yet officially supported".

Is it possible to bind BTK into Python 3.x? If so, can it be done in the same way as described on the official BTK page about its binding with Python 2.x?

I found a light-weighted implementation of reading and writing Motion Capture C3D files with Python 3.x. It's called c3d module and can be found at

If you want to support both 2.7+ and 3.4+ versions of Python, you can create btk-fake wrapper (a stub) for Python 3.4, using native btk for Python 2.7. For example, check out [https://github.com/dizcza/GesturesSpeech/blob/dev/MOCAP/local_tools/btk_fake.py]

Then rewrite your import to something like shown below.

try:
    import btk
except ImportError:
    import btk_fake as btk
