Hello @KYOUNGTAEK OH , Thanks for using Microsoft Q&A Platform.
Generally, Custom Neural models take longer time for training.
I believe interrupting the model may not be possible. In this case, you have the option to either wait longer or delete the model.
If permitted, you can delete the model directly from the studio; if not, please do so using the REST API.
Try to check your pricing tier and the service limits.
I hope this helps.
Regards,
Vasavi
