I have a strange behavoir/error when importing ftdy in Python 2.7:

ImportError: /usr/lib/python2.7/site-packages/_ftdi1.so: undefined
symbol: str2charp_size
Systeminfo: Python 2.7.16, SWIG 3.0.12/4.0.0, gcc version 7.3.1
20180425 [linaro-7.3-2018.05 revision
d29120a424ecfbc167ef90065c0eeb7f91977701] (Linaro GCC 7.3-2018.05)
libftdi: master branch
Any idea?
