google-assistant-demo doesn't work

[harry0890]

Q: I run google-assistant-demo fail because of "ctypes _dlopen can not open this library "/venv/lib/python3.4/site-packages/google/assistant/library/libassistant_embedder.so".

Note:

• This "libassistant_embedder.so" comes from "pip install -v google-assistant-library==1.0.1"
• My platform is 32bit ARMv7 linux, not Raspberry Pi2 or 3.

How can I solve this issue?

Did you pip install ctypes?

[harry0890]

Hi Fleker,
Yes, I already have installed ctypes. I can see dynamic library by cpython3.4 in this location.
/usr/lib/python3.4/lib-dynload/_ctypes.cpython-34.so
and the ctypes path:

/usr/lib/python3.4/ctypes/
__init__.py  _endian.py   macholib     test         util.py      wintypes.py

• Origninal, the source code try to dlopen libassistant_embedder.so

>>> from _ctypes import dlopen as _dlopen
>>> print(_dlopen('/venv/lib/python3.4/site-packages/google/assistant/library/libassistant_embedder.so', RTLD_LOCAL))
Traceback (most recent call last):
File "<stdin>", line 1, in <module>
OSError: File not found

• But, if I change another share object (eg: libportaudio), it could open successfully and return handling number.

>>> print(_dlopen('/usr/lib/libportaudio.so.2.0.0', RTLD_LOCAL))
18166401

Can you find the file /venv/lib/python3.4/site-packages/google/assistant/library/libassistant_embedder.so in a file explorer or is it not there either?

[harry0890]

Yeah, I can find the file /venv/lib/python3.4/site-packages/google/assistant/library/libassistant_embedder.so

/venv/lib/python3.4/site-packages/google/assistant/library/ # ls
LICENSE.third_party       __pycache__               event.py
__init__.py               assistant.py              file_helpers.py
__main__.py               auth_helpers.py           libassistant_embedder.so

and the file information:
