Problem using native client library + python bindings

[dsouza95]

Hello,

I have just updated my branch in order to get the new improvements that came with #805. Prior to #805, I never used the native client, and I am somehow struggling to use it. I tried using the pre-compiled libraries provided, but I face the problem seen in image 1. Other than that, I tried compiling the libraries from the tensorflow sources, and not using conda environments, but got the same results.
I am using Anaconda for Python 2.7. Tried compiling with both g++-4.8 and g++-5.0. I copied all .so files inside native_client while keeping the permissions to /usr/lib, a path defined in LD_LIBRARY_PATH.
I feel this is somehow related to where the deepspeech pip package is installed, but I am not really sure. Any ideas?
Thank you in advance :)

Daniel

I just verified, the libtensorflow_cc.so bundled in the latest native_client.tar.xz (from https://queue.taskcluster.net/v1/task/Mx3r25BbRaO45KdXZXToPQ/runs/0/artifacts/public/native_client.tar.xz) does have that symbol properly defined:

$ objdump -tT libtensorflow_cc.so |grep shape_inference16InferenceContext8WithRankENS0
00000000039f7600 g     F .text	0000000000000183              _ZN10tensorflow15shape_inference16InferenceContext8WithRankENS0_11ShapeHandleExPS2_
00000000039f7600 g    DF .text	0000000000000183  Base        _ZN10tensorflow15shape_inference16InferenceContext8WithRankENS0_11ShapeHandleExPS2_

Please make sure that you don't have a mess of previously installed libraries somewhere in /usr/lib or /usr/local/lib.

@dsouza95 We need more context, you don't give us the LD_LIBRARY_PATH value that you are defining, nor where libtensorflow_cc.so lives. Also, you should not be using run-tc-ldc93s1.sh, that's only for TaskCluster.

Under the proper LD_LIBRARY_PATH context, we would also need the output of ldd /usr/lib/libctc_decoder_with_kenlm.so. Also, it would help a lot @dsouza95 if you could copy/paste properly formatted text rather than images :)

Hello,
Thanks for the quick reply! I'm sorry I won't be able to show some logs of my situation from yesterday. My Mint just decided it wouldn't boot anymore, to which I decided to make a clean install. As it turns out, everything works like a charm now :) I probably messed up somewhere along the setup or afterwards.

Keep up the good work!
Daniel
