Unable to do one shot inference

[twmht]

I tried to compile everything from the source.

the tensorflow I used is from mozilla (https://github.com/mozilla/tensorflow)

after downloading the checkpoint and audio files you provided, I tried to do the inference on the checkpoint.

python DeepSpeech.py --checkpoint_dir ~/DeepSpeech/checkpoint/ --one_shot_infer ~/DeepSpeech/audio/2830-3980-0043.wav  --decoder_library_path ~/ten
sorflow/bazel-bin/native_client/libctc_decoder_with_kenlm.so

and the output is

Why can't load libdeepspeech?

Any suggestion?

https://github.com/mozilla/DeepSpeech/issues/1199, https://github.com/mozilla/DeepSpeech/issues/871, https://github.com/mozilla/DeepSpeech/issues/860

Both the libdeepspeech warning and lm.binary error should be fixed if you follow the suggestions in those issues.

Closing this since @samgd gave the proper answer :). Feel free to document in a new issue anything that is misleading / improperly documented so we can fix that.
