There is an issue with Noughts and Crosses.

As shown in the log below, the model cannot be downloaded from the cloud.

I am following Noughts and Crosses on a Windows 11 with Python 3.11, using ydf instead of tfdf as per your previous guide (https://groups.google.com/g/mlforkids/c/PZehIxaXV4U/m/3gJe1XahAQAJ).

Although I followed the guide in the PDF, cannot download the trained model at step 35 of the PDF guide. When I check the folder, there are no files.

Even after deleting the folder and trying again, the result is the same. The download fails.

Please help me.
thanks.

I'm not sure what problem you are facing but the error message suggests you are still using TFDF.

I've updated the sample code (see here for the updates) and the PDF guide (see here for the latest version) to use YDF - hopefully you can use these to correct your code.

I don't have a Windows computer to test this on, so I can't say with 100% certainty that this will work on Windows, but I can't see any reason why it wouldn't work.
