learning-polar-encodings-for-arbitrary-oriented-ship-detection-in-sar-images's Issues

ModuleNotFoundError: No module named 'polyiou'

ModuleNotFoundError: No module named 'polyiou',Is there a file missing here?

ValueError: Points cannot contain NaN

您好，请问在运行大些的数据集(如HRSID,RSDD-SAR)时为什么总会出现这个问题：仿佛是模型不太稳定。

TypeError: 'float' object is not iterable

I used the data you provided and run the code "python main.py --data_dir data/ssdd --num_epoch 120 --batch_size 8 --dataset ssdd --phase train --K 100" It seems that there are some data problems. And not all data could cause this.

Thansk a lot

请问7×7conv在哪里

你好，请问7×7卷积在哪里？代码中并未体现。感谢回复。

about your model

Hi, thank you for your work.
Can you share these two files MODEL_TO_EVALUATE.pth and MODEL_TO_DRAW_RESULTS.pth?
Looking forward for your answer.

assertion error

Thanks for you code, when i train the model, this error appears:
in decoder.py in polar_decode assert num_targets >0
This happens in the evaluation process, can you give some suggestions?

Could you share the annotation file of RSSDD dataset？

Could you share me your annotation file with c_x, c_y, w, h, α ？ My email :[email protected] Thanks!

error code

Thanks for you code, when i eval the model, this error appears:
Traceback (most recent call last):
File "main.py", line 65, in
ctrbox_obj.evaluation(args, down_ratio=down_ratio)
File "E:\Polar-master\eval.py", line 40, in evaluation

pts0, scores0 = decode_prediction(predictions, dsets, args, img_id, down_ratio)
ValueError: too many values to unpack (expected 2)

This happens in the evaluation process too, can you give some suggestions?
