Import Error #1

Open aallan opened 5 years ago

aallan commented 5 years ago

After replacing the setupvars.sh script I'm getting the following import error on running code,

Traceback (most recent call last):
  File "./benchmark_intel.py", line 3, in <module>
    from armv7l.openvino.inference_engine import IENetwork, IEPlugin
  File "/home/pi/openvino/inference_engine_vpu_arm/python/python3.5/armv7l/openvino/inference_engine/__init__.py", line 1, in <module>
    from .ie_api import *
ImportError: libinference_engine.so: cannot open shared object file: No such file or directory

looks like a copy of libinference_engine.so is located in the following places,

openvino/inference_engine_vpu_arm/deployment_tools/inference_engine/lib/armv7l/libinference_engine.so
openvino/inference_engine_vpu_arm/inference_engine/lib/armv7l/libinference_engine.so

any thoughts?

Hmm, looks like /home/pi/openvino/inference_engine_vpu_arm/python/python3.5/armv7l/openvino/inference_engine/init.py is not finding the shared libs

Manually check your environment variables, first

Also check this file exists : :/home/pi/openvino/inference_engine_vpu_arm//python/python3.5/libpython3.5m.so.1.0

How did you solve this @aallan ? I got the exact same problem. I followed your guide here: https://www.hackster.io/news/getting-started-with-the-intel-neural-compute-stick-2-and-the-raspberry-pi-6904ccfe963 Thanks!

I just found a solution, by exporting the corresponding path to the libinference: expor tLD_LIBRARY_PATH=/home/pi/inference_engine_vpu_arm/inference_engine/lib/armv7l
