Is there an install tutorial?

thanks in advance,

I’m not really sure what kind of tutorial you might want. Just install the flavor (C++ with native_client.tar.xz, Python or NodeJS) and run with the output_graph.tflite file that is packaged in the model release.

pip install deepspeech does work as well as npm install deepspeech.

#3

pip install deepspeech does work as well

#4

thanks @lissyx @abdellahnadi1 i took the simple path and installed using pip … then used

deepspeech --model models/output_graph.TFLite --audio my_audio_file.wav

which resulted in an error mssg tht tells me to reinstall numpy, which i did… same error results

anyone out there successfully installed to Raspberry Pi4 running Raspian Buster? pls advise!

thanks in advance
Jhave

IMPORTANT: PLEASE READ THIS FOR ADVICE ON HOW TO SOLVE THIS ISSUE!

Importing the numpy c-extensions failed.

  • Try uninstalling and reinstalling numpy.

  • If you have already done that, then:

    1. Check that you expected to use Python3.7 from “/home/pi/deepspeech-venv/bin/python3”,
      and that you have no directories in your PATH or PYTHONPATH that can
      interfere with the Python and numpy version “1.18.0” you’re trying to use.
    2. If (1) looks fine, you can open a new issue at
      https://github.com/numpy/numpy/issues. Please include details on:
      • how you installed Python
      • how you installed numpy
      • your operating system
      • whether or not you have multiple versions of Python installed
      • if you built from source, your compiler versions and ideally a build log

  • If you’re working with a numpy git repository, try git clean -xdf
    (removes all files not under version control) and rebuild numpy.

Note: this error has many possible causes, so please don’t comment on
an existing issue about this - open a new one instead.

Original error was: libf77blas.so.3: cannot open shared object file: No such file or directory
