Need Help with Computer Vision using local server

[deepika.garg]

Hello Everyone,

I am using Computer Vision using local server for automation of citrix based application(as no option install citrix extension on server).

Issues I am facing:

1. Automation is working on dev machine, using UiPath studio 2022.10.5 User Mode. But it’s not working on Production VM(using UiPath Studio Service mode 2022.10.5)

Error Message:
Response from server is not valid

I have already verified the troubleshooting steps:

2. I upgraded UiPath studio version from 2022.4.4 to 2022.10.5 and converted the project to windows version by clicking the highlighted option:
   
   

and i noticed all the screen scopes in cv screen scope activity are lost

Below is screenshot bfore converting to windows:

After converting to windows i lost all the screens and the CV Click, CV get text activities not working:

Properties of cv screen scope:

3. What happens if we untick CV methods in CV screen scope activity:
   
   

Apologies for the long post, but i would really appreciate the help to solve this issue.

Thanks Deepika!

1. Are there any proxy’s that you have to go through? Did you try pinging cv.uipath.com and see if you are getting response?
2. May be in conversion the screenshots are lost try recapturing the screens
3. If you uncheck element then only ocr is used which inturn uses images to detect and get the info…and not thw element selectors or cv selectors

Cheers

Hi Anil,

Thanks for the reply!!

No proxy’s have to go throough. I am using local server option, not on-premise or cloud server. So no need to reach cv,uipath.com

Hi!
Thanks for the detailed explanations.

1. I would please ask if it’s possible to update to the latest UIAutiomation package (23.4) and the latest ComputerVision.LocalServer package (23.4) and try again on Production machine.
   If this fails please send us the UiPath logs from that machine and if possible it would help to have the Event Viewer / Windows / Application logs.

2. Anil is right in that when upgrading it seems the screenshots are lost. They still should work on your dev machine (and on prod after we resolve the issue) but you can’t indicate / edit them. You have to reindicate the screen scopes and afterwards the activities if you want to redo them.

3. You can select if you want to use ComputerVision scope for Element detection (inputboxes / buttons/ etc…) or for OCR only (word / text detection)
   There might be some scenarios where you want to use only a different OCR, without sending anything to CV server (cloud or local)
   There is also the option of unselecting both options and in that case you can only have Image targeting

Thanks Stefan for your response.

I have raised a ticket with UiPath Technical support team. Provided ProcessMonitor, Application and Robot Logs.
They are investigating still. Seems like something is blocking from application side.
Process is not able to reach UiPath.computervision.localserver

Hi Everyone,

Finally, we were able to get to root cause for the issue. The VM where we were trying to run Computer vision using local server, was not supporting AVX2 for CPU.

With the help of IT support team, we are able to test the CV using local server is working on VM after changing the instruction set of VMware server.

Thanks!
