Error message in AutoML: "This dataset doesn't have annotations."

[julienpritwtpe]

Dear Community,

This is what I did:

• I created a dataset with 6 folders named AO1, AO2, AO3, AO4, AO5, and AO6.

• Each folder has between 200 and 400 one-page pdfs

• I zipped the 6 folders into one zip file

• I went to AutoML, added a "New Dataset", gave a name, selected "Multi-label Classification" (this is what I need), and pressed "Create dataset
• I then uploaded the zip file, selected a destination on Google Cloud Storage and pressed "Import"
• While it took some time, the importation was successful
• Unfortunately, when I want to "Start training", I am not able to because I have the following error message: "This dataset doesn't have annotations."

I do not see what I am doing wrong.

Any suggestion?

Thanks.

Julien
