Error during trie creation

DeepSpeech
#42

Ohkay. I get it.

But where exactly do i specify the path? i use a run file to train the model which is like this:

#!/bin/sh
set -xe
if [ ! -f DeepSpeech.py ]; then
echo “Please make sure you run this from DeepSpeech’s top level directory.”
exit 1
fi;

python -u DeepSpeech.py

“$@”

Everywhere here i have given the path correctly.

Also from your explanation I realize that i installed python package v0.1.1 in anaconda3 sometime in past while trying all things. Do i uninstall that?

#43

Please make an effort and pay attention: this is not the training that is problematic, this is your way to run inference. Just use the proper path when calling deepspeech. I don’t know your setup, I cannot tell you more. Maybe ./deepseech is enough, if it’s in your current working directory.

#44

As discussed earlier, i downloaded the binaries correctly but i was giving wrong path when calling deepspeech.

so i gave the correct path:

Prafful’s MacBook Pro:DeepSpeech naveen$ /Users/naveen/Downloads/DeepSpeech/DeepSpeech/deepspeech /Users/naveen/Downloads/DeepSpeech/results/model_export/output_graph.pb /Users/naveen/Downloads/DeepSpeech/alphabet.txt /Users/naveen/Downloads/DeepSpeech/TEST/engtext_3488.wav

dyld: Library not loaded: @rpath/libsox.3.dylib
Referenced from: /Users/naveen/Downloads/DeepSpeech/DeepSpeech/deepspeech
Reason: image not found
Abort trap: 6

I tried to resolve it by looking at the discourses but was not able to.

Do you know what i am doing wrong here?

#45

Please install libsox using brew.

#46

Okay, i installed ‘sox’ using ‘brew install sox’ and when i used ‘brew install libsox’, it said - 'Error: No available formula with the name “libsox” 'and ‘This similarly named formula was found:
libsoxr
To install it, run:
brew install libsoxr’

so i installed brew install libsoxr.

I still got the exact same error : ’ dyld: Library not loaded: @rpath/libsox.3.dylib’

Then, i got ‘otool -L deepspeech’

and i got:

deepspeech:
@rpath/libdeepspeech.so (compatibility version 0.0.0, current version 0.0.0)
@rpath/libdeepspeech_utils.so (compatibility version 0.0.0, current version 0.0.0)
@rpath/libsox.3.dylib (compatibility version 4.0.0, current version 4.0.0)
/usr/lib/libc++.1.dylib (compatibility version 1.0.0, current version 307.5.0)
/usr/lib/libSystem.B.dylib (compatibility version 1.0.0, current version 1238.60.2)

i understand from this that libsox is installed correctly but there is some problem in loading it.

#47

libsoxr is not what you want. I think the proper package name for bew is sox. The output of otool -L does not help us here, because it does not work as ldd under linux where it gives you the proper path. Check man dyld there are some environment variables that you can use to debug what happens at runtime. I’m not a macOS user, I cannot really help you more.

#48

I tried ‘man dyld’ but i was not able to resolve using that.

@JanX2 Hey, will you be able to help me with this as you had a similar issue here :- https://github.com/mozilla/DeepSpeech/issues/1051

i also tried : ‘install_name_tool -change /Users/build-user/TaskCluster/LightTasks/1/tasks/task_1511961329/homebrew/opt/sox/lib/libsox.3.dylib @executable_path/libsox.3.dylib ./deepspeech’ but i still i get the exact same error.

#49

I cannot help you more if you don’t check / document what is the dynamic loader doing. You need to read man dyld and run with the env var that will show you what is loaded: I know they exist, I don’t have a macOS. So please search a bit more.

#50

Hey @lissyx , i think i am very close and i did try different things as suggested. I have created the model. i have installed all the things which are required to call the inference. Its just that i am not able to resolve this.

Can you suggest me more things to try?

This is my recurring error while trying to run inference:
dyld: Library not loaded: @rpath/libsox.3.dylib

#51

I cannot help you more than I did, you need to check where libsox.3.dylib is … and why dyld does not find it, but I already told you all I know

#52

From https://developer.apple.com/legacy/library/documentation/Darwin/Reference/ManPages/man1/dyld.1.html, please give a try to those:

  • DYLD_PRINT_LIBRARIES=1
  • DYLD_PRINT_LIBRARIES_POST_LAUNCH=1
  • DYLD_PRINT_RPATHS=1
#53

I did entire process again on linux and i was able to resolve the libsox issues while running inference.

But currently i am getting this problem:

#54

Thanks a lot for this, this got resolved finally. My libpng was linked to some other program, so i had to force unlink it and then libsox got installed properly using ‘brew install sox’. Now the model is running successfully on mac. Still facing the issue mentioned in previous comment on linux.

#55

You are passing arguments in the wrong order. WAV should be the last one.

#56

Hey @lissyx,

I am trying to create an Indian audio model using around 80000 audio files.

This is the error i am getting while trying to train. Can you help me know if there is something wrong with the parameters i am assigning or its something else? :

  • check in the forum, I’m pretty sure there have been similar errors already debugged
  • start a new thread
  • make sure to properly format your text: right now, it’s totally unreadable, and parts of the useful output are being mangled

Also, you are training on a mac, it means you have no CUDA support there, it’s going to be very very slow.

Thanks,

I did not understand this part - “parts of the useful output are being mangled”. What exactly are you talking about? Checkpoint?

Use code formatting for console output.

Sir i am using cpu ubuntu 16.04.
i am also same issue. not create proper trie file.

…/DeepSpeech/native_client/generate_trie alphabet.txt lm.binary vocabulary.txt trie
Invalid label 
Aborted (core dumped)

it creates only empty trie file.

and i am running the deepspeech.py in my system it shows ,

I Validation of Epoch 9 - loss: 284.192108
I Early stop triggered as (for last 6 steps) validation loss: 284.192108 with standard deviation: 14.898946 and mean: 217.850253
I FINISHED Optimization - training time: 0:04:55
Error: Can’t parse trie file, invalid header. Try updating your trie file.

the validation result is improperly shown. but finally create a output_graph.pb model file. how to remove this error and how to create a proper trie file.

You seem to have made changes to vocabulary file with characters not in the alphabet ?
