How to create a mmap able model from the output graph pb file

I can see from the readme file here:
https://github.com/mozilla/DeepSpeech#making-a-mmap-able-model-for-inference

but i didnt understand this

> TensorFlow has tooling to achieve this: it requires building the
> target //tensorflow/contrib/util:convert_graphdef_memmapped_format

where do i find this client to achieve this:

convert_graphdef_memmapped_format --in_graph=output_graph.pb --out_graph=output_graph.pbmm

i am not able to find this in the taskcluster as well. Not sure where to
find this.

Please help in sharing the steps to complete this.

Thanks

Try ./convert_graphdef_memmapped_format [...] ?! Like as usual when
your binary is not in the PATH ?

Yes that was the issue. Thanks. slash
Also I can use this mmap model.dorectly like how I use the regular model
right ?? Or do I need to pass any new flags to achieve this ??

Thanks

,

I did download the file you mentioned in this thread and it is in my
current directory path. This is the command I am giving,

> convert_graphdef_memmapped_format
> slash --in_graph=models/output_graph_trained_model_2.pb
> slash --out_graph=model/output_graph.pbmm

But I am getting,

> convert_graphdef_memmapped_format: command not found

I also used,

> ./convert_graphdef_memmapped_format
> slash --in_graph=models/output_graph_trained_model_2.pb
> slash --out_graph=model/output_graph.pbmm

even here I am getting the same error. slash
where am I going wrong?

Thanks

I really cannot help you for that, the error sugests that the binary is
not here, but this is your system, I cannot do anything.

After download, you have to add executable permission for the file: slash
chmod +x convert_graphdef_memmapped_format

Then you can invoke the local command as: slash
./convert_graphdef_memmapped_format <your args>

How to use convert_graphdef_memmapped_format_lib.dms file in macOS ???

'convert_graphdef_memmapped_format.dms slash --in_graph=output_graph.pb
slash --out_graph=output_graph.pbmm'

That's the same as on any unix system, as explained above. I don't know
where you get convert_graphdef_memmapped_format_lib.dms from, it's
convert_graphdef_memmapped_format

Well, I'm sorry, but
this link is valid, and produces convert_graphdef_memmapped_format as
expected. Now, if you are on macOS, then it's not the proper link, and
using util/taskcluster.py as documented should produce you this link
https://index.taskcluster.net/v1/task/project.deepspeech.tensorflow.pip.master.osx/artifacts/public/convert_graphdef_memmapped_format

It might be possible that you have to rename to .gz and then gunzip
before use.

'no luck' is not really helpful: you report 'issues', refer to a
filename that makes no sense, but you share no error at all. I don't use
macOS, I can't help you if you don't give more context.
