Sorry to bother you again. After listening to your comments yesterday, I ran the following steps, but when I ran to “python export_descriptors.py configs/superpoint_hpatches.yaml superpoint_coco --export_name=superpoint_hpatches-v”，a code in "patches_dataset.py" reported the following error : ValueError: Shape must be rank 2 but is rank 0 for 'matmul_1' (op: 'MatMul') with input shapes: [3,3], [].

I have generated patches in dir"COCO/patches",and there is no problem reading the data,Iwant to ask why this error happended Looking forward to you reply, thank you very much. 1 @rpautrat

Hi,

Could you double-check that the patches dataset has been correctly generated and that the homographies are correctly read in the dataloader? Because from your error message, I suspect that your homographies might be empty...
