Dataset exists but fails to load and activate

April 19, 2015 - 8:25pm #8

Hello all,

I have a project that runs great in Unity and tracks all my image targets via webcam. The problem arises when publishing for my iPad. I bring the project into Xcode, add the security framework then have to re link my library search paths ( iOS plugins comes in funny ) and build. It goes on the iPad but won't recognize images. Wheni search the debugger it says 

"dataset exists

dataset ________ could not be loaded and cannot be activated."

I have tried re downloading my database from the target manager and that didn't work.  And before anyone says it my dataset is loaded and activated inside Unity.

 

thank you in advance!

I am experiencing this problem as well. I can track the image targets in Unity using my webcam, but nothing appears when using any of my ios devices.

I also can't make it work on iOS.

As previously mentioned, I get the following message:

dataSetExists

dataSetExists

Dataset __________ could not be loaded and cannot be activated.

 

Any idea on how to solve this issue?

Maybe the path to the folder with your project contains non-English characters? Check it plz.

Move the folder to another location or rename folder.

Hi, I actually have the same issue in our iOS build (Development and Production):

dataSetExists
dataSetExists
Dataset DBTestV1 could not be loaded and cannot be activated.

I tried different names for the DataSet (db_test_v1, db-test-v1, DBTestV1), but the problem is still here, on any iOS platform (tested on iPad 4, iPhone 4S and iPhone 5)

It works in Unity Editor, Android (tried on multiple smartphones and tablets) and PC / Mac, but iOS is the only platform I can't make it work.

ARCamera is present in scene, Load Data Set and Activate checkboxes are both checked.

Image Target Textures are in folder Editor/QCAR/ImageTargetTextures/DBTestV1.

DataSet (both DBTestV1.dat and DBTestV1.xml files) is in folder StreamingAssets/QCAR.

 

Versions:

Unity 5.2.0f3

Vuforia 5.0.5

Xcode 7.0.1
