Trying to build generate scorer package with bazel under deepspeech train v0 9 3 docker image

Hi everyone,

I'm trying to add some information to the PlayBook around generating a
new scorer file. I'm using;

and am following the v0.9.3 documentation for building a scorer
. I have
been able to successfully create an lm.binary and vocab-500000.txt
file.

$ ls
total 548
4 drwxrwxr-x 2 kathyreid kathyreid 4096 Feb 24 19:05 ./
4 drwxrwxr-x 6 kathyreid kathyreid 4096 Feb 24 19:05 ../
488 -rw-r--r-- 1 root root 499594 Feb 24 19:05 lm.binary
52 -rw-r--r-- 1 root root 51178 Feb 24 19:05 vocab-500000.txt

I'm now stuck trying to use generate_scorer_package.

I have attempted the following;

#build-generate-scorer-package)
but it fails with this error:

}

```
root0928acdb7399:/DeepSpeech/data/lm# bazel build --workspace_status_command='bash native_client/bazel_workspace_status_cmd.sh' --config=monolithic -c opt --copt=-O3 --copt='-D_GLIBCXX_USE_CXX11_ABI=0' --copt=-fvisibility=hidden //native_client:libdeepspeech.so //native_client:generate_scorer_package
ERROR: The 'build' command is only supported from within a workspace (below a directory having a WORKSPACE file).
#workspace

file in the filesystem.

What should I try next?

You need to run bazel build from within tensorflow directory, not
data/lm

I would have expected people to just download the released binaries
rather than going through the pain of rebuilding. At least, this is what
we advertise as default course.

Super helpful, now I understand what I was doing wrong. Merci beaucoup!

I will also use the packaged native_client rather than compiling from
src.
