Are there any elements in the results?

[LW091]

Looks like a problem with the data set. I've fixed it. But I have a question, which configuration file was used for the test? Is it a cfinet‘s config profile? But this project doesn't have that model.Maybe sodaa-benchmarks/rotated_faster_rcnn_r50_fpn_1x.py?

[LW091]

I do not know that soda-a dataset how to test.take it to the CFINet? maybe just change the dataset?

[shaunyuan22]

When you want to implement CFINet on SODA-A dataset, except change the dataset, the CRPN codes could be directly transfered to here while the implementation of FIHead needs to be aligned with OBB RoIHead, please refer to this issue.
