Specifying the Python interpreter and crash in :JediDebugInfo

I can :Pyimport packages from the standard library, but not from libraries installed via pip.

:Pyimport tensorflow
jedi-vim: Cannot find tensorflow in sys.path

:Pyimport os                                                                         
"/usr/lib/python2.7/os.py" [readonly] 740L, 25769C

I believe the problem might be that Jedi doesn’t use the Python interpreter at /usr/local/bin/python3.6 for which I installed the packages, which is different from the default Python interpreters on my system (/usr/bin/python2 and /usr/bin/python3). How can I set the Python interpreter that Jedi uses?

This is the output of :verbose JediDebugInfo, where I replaced my home directory by <HOME>:

I tried to set let g:jedi#force_py_version = 3, but this causes a crash when opening my test file:

Update: deoplete-jedi has an option to specify the Python interpreter, and it uses python available in PATH rather than Vim’s Python interpreter by default. Specifying let g:deoplete#sources#jedi#python_path = '/usr/local/bin/python3.6' solves the issue for me.

Thanks, this patch fixes the issue. It works now, even with +python/dyn, +python3/dyn.
