PPC pretrained weights

❓ Questions and Help

@mrlooi
Can you public your pretrained weights on PPC dataset ?

[mrlooi]

Hey unfortunately I don't have the pretrained weights with me. In any case the MSCOCO pretrained weights should be more better - it's more general

@mrlooi
In addition,
You have not published your paper yet, have you ?

[mrlooi]

Nope, it takes work, and doubt it's going to make much of an impact anyway. I'm not a full time researcher, so publications and citations are not as important to me xD

I often meet this error after some training iterations:

Can you tell me how to solve this issue ?

[mrlooi]

It would seem that the input batch size is empty (0 x 1 x ...). A good way to check is backtrack where the input became empty. I haven't seen this issue before, but if you do find out the cause, please let me know

@mrlooi
Yeah sure, Iam training with my own dataset to see if this error still occurs.

[trungpham2606]

@mrlooi
I think the error comes from the model not about the dataset.
For PPC dataset, i had printed out the images when the errors come out.

The error comes with different images each times.
The objects inside the images I guess they're not too small.
Do you have any ideas about this ?

[mrlooi]

Hey good question. I think it could be that the ground truth rotated bboxes for those objects did not have good IoU fit with any of the rotated anchors

I had changed some threshold for being able to train PPC dataset.
Thank you for your prompt support!

@mrlooi
Excuse me but can you please give me some sources of reference you had used in your work ?
Does RRPN you used come from this paper: Arbitrary-Oriented Scene Text Detection via
Rotation Proposals ?(https://arxiv.org/pdf/1703.01086.pdf)

[mrlooi]

Yes RRPN and MaskRCNN are the main ones

@trungpham2606 Hi, could you tell me what thresholds did you change for training PPC dataset? Thanks~
