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

How to use convert_graphdef_memmapped_format_lib.dms file in macOS ???
“convert_graphdef_memmapped_format.dms --in_graph=output_graph.pb --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

@inforahul92 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 with this hack 
“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.

I just gave you the proper link above. It seems there’s a regression in the code and the url you report here is wrong. Hence 404.

Issue resolved now,
The problem was with safari browser. Whenever I am opening your given URL “https://index.taskcluster.net/v1/task/project.deepspeech.tensorflow.pip.master.osx/artifacts/public/convert_graphdef_memmapped_format” in Safari it is downloading convert_graphdef_memmapped_format file in .dms format. Then I tried the same url into chrome browser and it is downloading convert_graphdef_memmapped_format file in the same format what I was expecting.

@lissyx Thank you so much for the help 
Weird. Could you file an issue for both problems? One for the invalid url and one for mentioning in the docs the safari’s behavior

@lissyx I have raised below issue
How to download convert graphdef memmapped format binary file in safari broswer?
Well, I was more thinking about a Github issue …
this link gives me this on chrome:
{
“code”: “ResourceNotFound”,
“message”: “Indexed task not found\n\n—\n\n* method: findArtifactFromTask\n* errorCode: ResourceNotFound\n* statusCode: 404\n* time: 2019-09-29T20:32:01.249Z”,
“requestInfo”: {
“method”: “findArtifactFromTask”,
“params”: {

“indexPath”: “project.deepspeech.tensorflow.pip.master.cpu”,
“name”: “public/convert_graphdef_memmapped_format”
},
“payload”: {},
“time”: “2019-09-29T20:32:01.249Z”
}
}
Yes, it’s normal, it expired. I insist, you should read and use util/taskcluster.py with proper branch argument.
thank you very much for replying.
python util/taskcluster.py --branch v0.5.1 --source tensorflow --artifact convert_graphdef_memmapped_format --target native_client_bin
python util/taskcluster.py --branch r1.13 --source tensorflow --artifact convert_graphdef_memmapped_format --target native_client_bin
Both gives me HTTP Error 404: Not Found
What is wrong in my command?
Nothing, it’s just that artifacts expired.
As soon as https://tools.taskcluster.net/groups/QGJDilIzRnSuPWmKLNnKyw completes, you should be able to get them.
