# Building DeepSpeech Binaries

If you'd like to build the DeepSpeech binaries yourself, you'll need the following pre-requisites downloaded and installed:

DEEPSPEECH.cdx deepspeech.commands DEEPSPEECH.pages DEEPSPEECH.warc.gz discourse.mozilla.org html-to-markdown.sh shell-conver-html-to-split-posts.sh sorted-deepspeech-posts Mozilla's TensorFlow r1.13 branch
DEEPSPEECH.cdx deepspeech.commands DEEPSPEECH.pages DEEPSPEECH.warc.gz discourse.mozilla.org html-to-markdown.sh shell-conver-html-to-split-posts.sh sorted-deepspeech-posts General TensorFlow requirements
DEEPSPEECH.cdx deepspeech.commands DEEPSPEECH.pages DEEPSPEECH.warc.gz discourse.mozilla.org html-to-markdown.sh shell-conver-html-to-split-posts.sh sorted-deepspeech-posts libsox

It is required to use our fork of TensorFlow since it includes fixes for common problems encountered when building the native client files.

If you'd like to build the language bindings or the decoder package, you'll also need:

DEEPSPEECH.cdx deepspeech.commands DEEPSPEECH.pages DEEPSPEECH.warc.gz discourse.mozilla.org html-to-markdown.sh shell-conver-html-to-split-posts.sh sorted-deepspeech-posts SWIG
DEEPSPEECH.cdx deepspeech.commands DEEPSPEECH.pages DEEPSPEECH.warc.gz discourse.mozilla.org html-to-markdown.sh shell-conver-html-to-split-posts.sh sorted-deepspeech-posts node-pre-gyp (for Node.JS bindings only)

## Dependencies

If you follow these instructions, you should compile your own binaries of DeepSpeech (built on TensorFlow using Bazel).

We also have libdeepspeech on JCenter:
https://bintray.com/alissy/org.mozilla.deepspeech/libdeepspeech

And you can rely on higher-level mozillaspeechlibrary from
https://github.com/mozilla/androidspeech/ as well

Hi, lissyx, I also have another question on the import deepspeech.

I know after deepspeech(v0.2), slash ' from deepspeech import Model slash ' is
correct, but it's not suit for deepspeech(v0.1).

Now I am testing deepspeech(v0.1), How can I correctly import Model from
deepspeech?

Take a look at the examples / bindings in v0.1.1 ?
