Hi Microsoft!

I'm in love with your product. Especially Microsoft Power Automate (Desktop). Been doing some experiments with AI builder recently, to see whether I can infuse AI in my automation flows.

However when I'm trying to train my model it states:

Couldn't train model. Try again later.

Please wait a moment and try again.

It doesn't state what the error exactly is, so I hope u can help me. Fyi: it worked with 3 collections, but started giving this error since I added the 4th and 5th.

Thank you so much in advance!

This is a rare issue and there could be several causes

- A temporary service outage. In this case, you could reedit and train the model again to check if the problem still occur

- A document which is not properly supported. In this case, you could try to edit your model and remove collection 5 and retrain, then do the same with 4 only. I understand that this could be a bit painful

The faster way would be to provide the environment and model id available in the URL so we could investigate https://make.powerapps.com/environment/ENV_ID/aibuilder/models/MODEL_ID

Thank you so much for your reaction Cedrick!

Option 1: I also thought this was the case. However, the problem occured yesterday and today it's still there.
Option 2: Yep.. (Unfortunately) I've tried this already. I tagged around 50 documents and deleted them to see whether they were the cause. They werent.

I'll send you a PM regarding the model ID. Thank you again!

Hello Tjan,

I have a similar issue with a Prediction model that I'm trying to create.
Tested in multiple environments and the result is the same (the error you display above).
As far as I know, it's a known issue and the team is working on resolving it (open ticket).

We see a timeout.

We need further investigations.

We will reply to this thread when we have a concrete diagnostic.

In the meatime, can you try to retrain the model please?

Thank you so much Cedrick.

Thanks for the hard work from the team 💪

@CedrickB @JoeF-MSFT Hi team! Regarding the above mentioned error, I did A LOT of testing. Including the tagging of documents and deleting them afterwards 😥. I found out the error will be thrown when having more than 125 documents tagged. As it seems, the amount of collections doesn't influence the occurence of the error (I tested with 4,5,6 collections). The amount of files within a collection does also not affect it (I tested with 35 in a collection). I hope this contributes to the investigation. Thank you so much for your effort and time.

Is it possible that you reached the dataset size limit?

The combined file size of the documents used for training per collection must not exceed 50 MB.

See https://docs.microsoft.com/ai-builder/form-processing-model-requirements

Thanks for your reply. I checked this already!

The max amount of MB per collection was 2 MB in my case.
