  • Goal: Pass Image URL to google vision to perform OCR.

  • Steps: 1. Tried to resize images from 2048x2048 to 128x128.
    2. Tried streaming of images using io.BytesIO().
    But, Facing "The code terminated for an unknown reason. Potentially, the memory limit 256 Mibs was breached.".

  • Details: """
