TensorFlow Error After Upgrade to 4.3 with multiple "TeamCode" #625

Closed EddieDL closed 6 years ago

EddieDL commented 6 years ago

When you attempt to run the TensorFlow example I get the following in the log and the OpMode shuts down. This is on the Moto E4.

Fixed in 4.3

So I figured out my problem @cmacfarl and it isn't as simple as just upgrading. We have two teams so we do not use the standard TeamCode.

Because the change modified the build.release.gradle in TeamCode you have to make the same changes to all of your duplicate TeamCode files. I should have been watching for it, but didn't.

I am changing the title to reflect what my real issue was.

The following needs to be added to your build.release.gradle file.

implementation (name: 'tfod-release', ext:'aar')
implementation (name: 'tensorflow-lite-0.0.0-nightly', ext:'aar')
