READ Task canceled: system.Threading.Tasks.TaskCanceledException: A task was canceled

Question

READ Task canceled: system.Threading.Tasks.TaskCanceledException: A task was canceled

I am getting some READ OCR errors that is printing the message shown in the screenshot below. I am using the code provided by Microsoft in their getting started guide. I am running the code with multiprocessing (4 cores) so there are multiple calls to the API at a time. I have the plan that allows me 10 calls per second so I don think making too many calls per second is the problem.

Any help would be appreciated!

Also, ensure that you are using a 1 second interval between requests.

I have a parent program that creates 6-8 forks of the Sample code that Microsoft has for the Cognitive Service READ. The files that are being passed to Microsoft are on my local machine. The only difference I have in my code from the Sample code is the output it saved to a file in a specific format.

Based on @GiftA-MSFT answer I am guessing that I would need to put a 1sec delay between the forks, correct?

Thank you

Correct, you can call the API using parallel batch processing capped by the TPS limit. However, we recommend that you add a 1 second interval between API requests or tune the interval and observe the performance.
