Hi @Dhruv00710, for using discord you can simply login via browser after clicking the invite link: https://discord.gg/qFv2Vqf

Also before that, can you follow an issue template mentioning the specs of your desktop/device such as OS/memory specs?

Desktop (please complete the following information):

• OS: [e.g. MacOS, Linux, Windows]
• Python version
• OpenCV version

[Udayraj123]

Quoting an SO answer and a github issue:

Try installing the 64 bit versions of Python and OpenCV, which should have enough address space, even if you end up swapping to disc

Feel free to reopen if the issue persists :)

[Dhruv00710]

sirji, i am also use Twain library and its works only 32 bit python. And Twain library is not work in 64 bit python. so my software developed in 32 python.

I'm afraid you're on your own if it's not reproducible for me. You can maybe try commenting out the code which is throwing the above error (template matching). Try removing CropOnMarkers plugin and see if rest of the code runs fine

[Dhruv00710]

ok sir do it i remove CropOnMarkers. And old template & OMR SHEET is below.

Template is: { "pageDimensions": [ 1651, 2335 ], "bubbleDimensions": [ 32, 32 ], "preProcessors": [ { "name": "CropOnMarkers", "options": { "relativePath": "omr_marker.jpg", "sheetToMarkerWidthRatio": 16 } } ], "fieldBlocks": { "Roll_no": { "fieldType": "QTYPE_INT1", "origin": [ 236, 534 ], "fieldLabels": [ "r1", "r2", "r3" ], "bubblesGap": 96.4, "labelsGap": 40.8 }, "MCQBlock1a1": { "fieldType": "QTYPE_MCQ5", "origin": [ 135, 721 ], "bubblesGap": 51.4, "labelsGap": 39.8, "fieldLabels": [ "q1..20" ] }, "MCQBlock1a2": { "fieldType": "QTYPE_MCQ5", "origin": [ 135, 1527 ], "bubblesGap": 51.4, "labelsGap": 39.8, "fieldLabels": [ "q21..30" ] }, "MCQBlock1a3": { "fieldType": "QTYPE_MCQ5", "origin": [ 135, 1933 ], "bubblesGap": 51.4, "labelsGap": 39.8, "fieldLabels": [ "q31..40" ] }, "MCQBlock1a4": { "fieldType": "QTYPE_MCQ5", "origin": [ 425, 721 ], "bubblesGap": 51.4, "labelsGap": 39.8, "fieldLabels": [ "q41..60" ] }, "MCQBlock1a5": { "fieldType": "QTYPE_MCQ5", "origin": [ 425, 1527 ], "bubblesGap": 51.4, "labelsGap": 39.8, "fieldLabels": [ "q61..70" ] }, "MCQBlock1a6": { "fieldType": "QTYPE_MCQ5", "origin": [ 425, 1933 ], "bubblesGap": 51.4, "labelsGap": 39.8, "fieldLabels": [ "q71..80" ] }, "MCQBlock1a7": { "fieldType": "QTYPE_MCQ5", "origin": [ 720, 721 ], "bubblesGap": 51.4, "labelsGap": 39.8, "fieldLabels": [ "q81..100" ] }, "MCQBlock1a8": { "fieldType": "QTYPE_MCQ5", "origin": [ 720, 1527 ], "bubblesGap": 51.4, "labelsGap": 39.8, "fieldLabels": [ "q101..110" ] }, "MCQBlock1a9": { "fieldType": "QTYPE_MCQ5", "origin": [ 720, 1933 ], "bubblesGap": 51.4, "labelsGap": 39.8, "fieldLabels": [ "q111..120" ] } } }
