Action
Upload Training Images by URL
Tool to upload training images by url to a specified ocr model. use when adding urls of images to a model for training purposes.
Why this helps
Training image links can get buried in Slack, requiring a second pass to move them into the intended model.
- Turn an approved image link into a training image upload.
- Keep the upload tied to the decision and target model.
- Reduce the chance that approved examples remain unused in Slack.
Setup
Build it in a few focused steps.
- 1Connect Slack and Nano Nets once in the Notis portal.
- 2Create an automation in Automations, New Automation, and name it.
- 3Describe in one instruction how to verify approval, extract the image URL and target model, and upload the URL as a training image.
- 4Pick the Slack channel message trigger and choose where run reports should go.
- 5Test with one real approved image URL and specified model.
Questions about this workflow
Does the URL need to point to an image?
Yes. The Nano Nets action is for uploading training images by URL, so include a usable image URL.
Does the action create the OCR model?
No. The target OCR model needs to exist. This action adds a training image by URL.
