MONAI nodule detection model training and handling zero nodule datasets

Hello
Thank you for the MONAI team. I have been training a nodule detection model using

Among my datasets I have some which have 0 nodules in them. And i think i get a error log as shown below for such cases

I have applied the correction mentioned there

i.e
boxes = torch.reshape ( boxes, [ 0, 4 ] ) as follows:

but i still get the same error log as shown above. May i know the reason for this and the solution for the same please. Also I have used datasets that have 0 nodules and a nnDetection (https://github.com/MIC-DKFZ/nnDetection) model trains well under such situations.

The report concerns training a nodule detection model with datasets containing zero nodules and includes an error log in an attached image. Start by reproducing the error with a zero-nodule dataset and inspect the reported failure; done means training completes successfully for such datasets without the same error.
