RPC Timeout

[jtgreen]

This may be an easy one. Im simply trying to run the stoke width transform. The setup works great for straight tesseract, but when I run the test curl for the stoke width transform, I get an RPC timeout. My suspicion is my box is taking too long with the transform so the RPC is kicking back that general network error thinking the call had failed (it not knowing if its a slow network or what).

Here is the error: john@...$ curl -X POST -H "Content-Type: application/json" -d '{"img_url":"http://bit.ly/ocrimage-swt","engine":"tesseract", "preprocessors":["stroke-width-transform"]}' http://${DOCKER_HOST}:${HTTP_PORT}/ocr

Unable to perform OCR decode. Error: Timeout waiting for RPC response Thoughts? Thanks!

I have a feeling the stroke width transform phase might be failing completely, and so the httpd daemon never gets a result on the message queue.

Are there any logs on the worker doing the stroke width transform? On the host OS where you kicked off the docker container, run docker logs <container id>

Thanks, Ill check it out. I must say, im completely unfamiliar with docker (I had looked into your great project for this feature I saw on the tesseract mailing list). 

Ill sleuth out what I can and post back.

What platform are you running it on? GCE, Tutum, local Vagrant? I may be able to give some guidance.

Im very sorry. I literally forgot to set the environment variable for the password. So you were right: it was completely failing on the server, butsimply  because of credentials! 

Turned out to be nothing but Im very excited about your project,

Thank you for your prompt responses and kind willingness to help,

John

@jtgreen thanks, I'll close the ticket. Can you let me know how you are kicking things off? Are you using https://github.com/tleyden/open-ocr/blob/master/launcher/launcher.sh? It's supposed to check for the password environment variable and fail if it's not defined.

I'm just wondering how I can improve things to help other users running into the same problem.

I'm getting this same error but I have set the password. Worker logs don't have anything

[kimmobrunfeldt]

I didn't have the preprocessor worker started as documented here https://github.com/tleyden/open-ocr/wiki/Stroke-Width-Transform#start-an-additional-worker

Same as this issue: https://github.com/tleyden/open-ocr/issues/24

@kimmobrunfeldt can you open a new issue instead of using this one? (since it's closed)

[kimmobrunfeldt]

@tleyden sorry I thought my issue related to this. But I got that solved by following instructions in issue thread #24.
