in the directory ncappzoo/apps/live-image-classifier ,i try to sudo make mobilenet,it have such error:

another question:

in the directory ncappzoo/apps/live-image-classifier ,i try to sudo make run,it returns the following error:

ImportError: No module named caffe, so i add below code in Makefile:

ifneq ($(findstring movidius, $(PYTHONPATH)), movidius)
           export PYTHONPATH:=/opt/movidius/caffe/python:$(PYTHONPATH)
  endif

it works very well , i don't know if it is a bug for you.

@Tome_at_Intel @PINTO ,can you help me? now i found out that all tensorflow's examples were wrong with the same error:

tensorflow.python.framework.errors_impl.NotFoundError: /usr/local/lib/python3.5/dist-packages/tensorflow/contrib/data/python/ops/../../_dataset_ops.so: undefined symbol: _ZN6google8protobuf8internal9ArenaImpl10AddCleanupEPvPFvS3_E

please help me,thanks!

https://ncsforum.movidius.com/discussion/948/procedure-for-make-examples-ncsdk-v2-05-00-02-raspberrypi3-raspbian-stretch-ubuntu16-04#latest

Please try tensorflow 1.8.0 or 1.9.0.

idata · ‎08-03-2018

@PINTO thanks very much, i install tensorflow 1.9.0 and it works!

idata · ‎08-09-2018

@PINTO but the NCSDK 2.05 only supports tensorflow <= 1.7.0, my device is Raspberrypi 3, I have to face the problem directly,

idata · ‎08-09-2018

@zufeifei

I know that.

It is not officially supported, but please be relief so that it works.

I and luna are operation verified.

If you dislike that you are not officially supported, I will not recommend it.

There is no doubt that the behavior of Tensorflow 1.7.0 is unstable.

idata · ‎08-09-2018

@PINTO thanks for your time, and does it mean that I could remove tensorflow-1.7.0 and install the tensoflow with version 1.9.0 to solve the problem

idata · ‎08-09-2018

@PINTO OH! I operation verified,

sudo pip3 uninstall tensorflow

sudo pip3 install tensorflow

then the problem solved,

thank you for a lot！
