Uncaught (in promise) TypeError: Cannot read property 'reduce' of undefined

When creating a model using AutoML with Multi Classification.

Getting this error from tensorflowjs when running const model = await tf.automl.loadImageClassification('/model/model.json');

Model Multi-Classification, Edge, Exported for Tensorflowjs

Nothing crazy here just a simple export and run from browser. The model works fine when deployed in GCP with "Test&Use".

@pyu10055 Not sure if this falls in your court :)

[ghafran]

Just tried this on models that were working previously. Looks like something changed during the model export or creation process on AutoML that is causing this issue.

[ghafran]

This seems to be fixed today. I retrained the models this morning and exported. Worked as expected. I love voodoo magic self healing :)

This issue popped up again :(

@ghafran can you share your model file? thanks

[ghafran]

Attached. Just exported it from AutoML Multi-classification using edge, faster performance. Getting same error. @pyu10055

[ghafran]

@pyu10055 thanks for posting the fix. Your a life saver!

[ghafran]

@pyu10055 I see the fix has been completed. Can I regenerate the model now or do we need to wait for a production push? Thanks.

@pyu10055 This issues still seems to be happening. Do we know when the fix will be deployed?

Even I am also facing the same issue :( The model I exported about 3 weeks ago is working perfectly fine but the model I exported yesterday is not working and showing the error "cannot read property reduce of undefined" :(

[ghafran]

Our customers are getting agitated. Do have an estimate of when this will be pushed?

[pyu10055]

@ghafran The fix will be available in the next release, but meanwhile you can lock your tfjs version to 2.6.0, that should temporarily solve your problem.

[Vivek1907]

I think I found a solution

In your model.json file just remove this line:- "modelInitializer": {"versions": {}},.

@ghafran so here is the modified model.json

model_json.zip

Replace your model.json with the above file

So, this should work even with the latest tfjs version

[ghafran]

@Vivek1907 that work around fixes it! Thank you!

[zholmes1]

@Vivek1907 Worked for me too. Thanks!

[ghafran]

Just trained, exported, and ran the models with latest versions. All is good now.
