Terminate called after throwing an instance of 'std::system_error'

roshangm1 · July 3, 2018, 1:11am

Hi, I was trying to install and run DeepSpeech ClI on Intel AI DevCloud instance but got this error while starting off.

[u8748@c009 ~]$ deepspeech models/output_graph.pb audio-test.wav models/alphabet.txt
Loading model from file models/output_graph.pb
terminate called after throwing an instance of 'std::system_error'
  what():  Resource temporarily unavailable
Aborted

I feel that this is due to some kind of restrictions in the instance but I am not sure about it and also not sure how to solve this. Please let me know if you have any idea around this.

How much memory do you have on this ?

roshangm1 · July 3, 2018, 7:08am

This the output from cat `/proc/meminfo`:

MemTotal:       16267196 kB
MemFree:          157872 kB
MEmAvailable:   14090928 kB

So that’s 16GB. It should be okay then. Without more details on your system and the potential limitations, it’s going to be hard to do divination

roshangm1 · July 3, 2018, 7:47am

Hmm okay. If you want, I can provide more details about my system. I am not much familiar with this error. What details you want to know about ?

This is the one I am using right now.

Thanks. Any particular reason you try to use this platform? I don’t even know where this std::system_error comes from. Can you gdb into ? Or try with the C++ native client code to check if it’s because of Python ?

roshangm1 · July 3, 2018, 8:12am

By platform, did you mean DevCloud ? If yes, they are providing a kind of powerful instance free for educational purpose. So not having enough powerful device with me, I am using this platform.

Yes, I think, I can gdb into:

I am not sure how to check what is causing the issue. Any link or guide you can provide to test this ?

lissyx · July 3, 2018, 8:13am

No. Again, try to run within gdb and/or try with the C++ native client: https://index.taskcluster.net/v1/task/project.deepspeech.deepspeech.native_client.v0.1.1.cpu/artifacts/public/native_client.tar.xz

roshangm1 · July 3, 2018, 8:14am

Oh okay. Let me try this. I will let you know how it goes.
Thank You!!

lissyx · July 3, 2018, 8:17am

You don’t need that powerful system for just running inference, and requirements are already going down with v0.2.0 upcoming.

roshangm1 · July 3, 2018, 3:13pm

Awesome thing to know about. Actually, my current device is terrible. Thanks for the information though. I will try to do things in the instance for now and later will try in my device also.

lissyx · July 3, 2018, 4:49pm

How much terrible is terrible ?

roshangm1 · July 5, 2018, 1:48am

It’s 2011 Macbook Pro with 4GB RAM. Isn’t it terrible ?

roshangm1 · July 5, 2018, 1:55am

@lissyx BTW, I tried to do this with native client but now got another error instead:

terminate called after throwing an instance of 'St9bad_alloc'
which seems to be a memory issue for me.

Any words on this ?

roshangm1 · July 5, 2018, 2:28am

Memory it was. In the instance, there was restriction on using the memory for user node. What I had to do was, make a job file for the code(task) and schedule it and then only it would use entire memory. It was the issue with the Devcloud solely.

Thanks for your help. You are really nice.

Does it have AVX extensions ?

roshangm1 · July 9, 2018, 10:02am

Got this result while doing grep. I actually don’t know about AVX and also about this result. Sorry.

lissyx · July 9, 2018, 10:04am

Seems like there’s AVX exposed, but you confirmed it was an issue related to the memory

roshangm1 · July 9, 2018, 10:20am

Yeah!! Working okay for now at least.
