500 Internal Server Error on localhost? about deepspeech-websocket-server

[daanzu]

The server and the recognize URL are for websocket connections only, not normal HTTP GET requests. The included client uses that for low-latency streaming; are you using it?

It wouldn't be hard to add support for receiving GET/POST requests containing audio, but it's not there currently.

Thanks for getting back to me @daanzu

My server code always seems to say listening to 'http://...' not 'ws://...' when i run the server.py file with the pretrained deepspeech model parameters. When i run python client.py, which when i checked the code already has the 'ws://...' address, it says the following in anaconda:

(base) C:\Code\python\deepspeech-websocket-server-master>python client.py Connecting to 'ws://localhost:8080/recognize'... Listening (ctrl-C to exit)...

By the way this hangs and 'ctrl-C' does nothing, i need to restart anaconda. Also, when i put ws://localhost:8080/recognize into my Google Chrome browser, i get the following error msg, despite it saying in anaconda that it is connected to that localhost via ws.

Any idea how i can get either the client.py or server.py on anaconda on Windows 10?

[daanzu]

Hmm, I don't use Anaconda, and I'm no websocket expert (thankfully haven't needed to debug it much). Actually, I just realized that I haven't tested the server running directly in Windows, only in WSL. (This was developed before DeepSpeech ran on Windows.)

[ulimmeh]

Ok thanks. I would really like to get this working using anaconda on Windows. Anything you can suggest to help me resolve this?

[daanzu]

I just tried it with your configuration except vanilla python and it worked. Maybe an anaconda issue?

[ulimmeh]

Hmm, can you walk me through your steps? What version of deepspeech do you use? Also, what version of the pre-trained model do you use?

[daanzu]

I used python 3.6.3 from python.org, installed the requirements and the latest deepspeech from pip, and the 0.5.1 pretrained model.

[ulimmeh]

But did you do this on Windows? Pip on what command prompt? What IDE did you use for python?

[daanzu]

Windows 10; normal non-powershell command prompt; no IDE.
