Trainable classifiers debugging/error logs

Ahmed Sh 100

Hello,

I am testing out trainable classifiers and need to know how to investigate training failures in detail?

Some errors are vague such as "Failed due to training error" or "Invalidlocationserror" and clicking on review test results does not show details.

Where is log stored? How can we review errors further? Any help is appreciated.

@Ahmed Sh - Thanks for the question and using MS Q&A platform.

Could you please share the steps which you had followed for testing out trainable classifiers and the exact error message with the screenshot?

Looking forward for your response.

Hello PRADEEPCHEEKATLA-MSFT,

-First I tried creating a classifier with multiple sharepoint site/folder sources for positive and negative samples. Error was as attached below.

-I tried to then create one sharepoint site and two folders, one for positive and one for negative samples. This generated an result of about 36% if I can recall correctly as one of the positive samples got marked as negative and vice versa.

-I tried to create one sharepoint site with one folder for positive samples and one sharepoint site for negative samples.

-For positive samples I used variations of the same excel document, i.e. same pattern but different entries and some entries are similar, for negative entries I used variations of the same excel document as well.

-All those attempts generated the below error.

-I am just trying to know if I can get a location or cmdlet to check further what the error in detail is and how to work on it, That is my main need for now.

@Ahmed Sh - I agree that this issue looks strange and I wasn't able to reproduce this issue. If you have a support plan could you please file a support ticket for deeper investigation and do share the SR# with us?

@PRADEEPCHEEKATLA-MSFT Hi, I managed to get one created, I tried to explain here some tips as much as I could in case it can be helpful since not much documentation is available out there.

This does not provide a solution to the original issue, which is where to find the logs for trainable classifier errors such as "InvalidLocationsError" or others related to "failed due to training error". I continue to run into this issue and am wondering if there are specific permissions required on the SharePoint sites used for training the data. I am going to open a ticket as well, but this comment does not provide resolution.

@Ryan Tsamouris Yes MS support were not very helpful thus it is likely this information is visible case by case through product group but not friendly way to identify through tenant side gui/PS etc....

So far regarding steps to create the classifiers, data collection and SPO site layout, I have created this guide as this is the only way it worked with me .

-Feel free to let me know if you have any other info from MS support. Thank you in advance.
