Hi, @javier-castan I've met the problem and how to solve it? Could you tell me?

in the Annotation folder I run `grep -rl '0' ./ | xargs sed -i 's#0#1#g'` I got: `sed : no input files` just like @harora . I want to know...

Thanks,@kevinkit, I’ve tried， but didn’t work. anybody help us?@CharlesShang

I solved that problem.

@vaklyuenkov I just comment `img.astype(np.uint8),` and that works. `Img.astype(np.uint8)` returns a copy of the array converted to the uint8 type, that will speed up the training time. If you comment...

@kevinkit your answer is right, but how can I do to solve it? it means I need get the img's data?detail?

@kevinkit @tweedmorris your answers have helped me to solve the problem. Thank you very much!

可以试下 paddle.linalg.matrix_power 文档：https://www.paddlepaddle.org.cn/documentation/docs/zh/api/paddle/linalg/matrix_power_cn.html 示例： ### torch >>> x = torch.matrix_exp(torch.tensor([[2,0],[0,2]],dtype=torch.float)) >>> x tensor([[7.3891, 0.0000], [0.0000, 7.3891]]) ### paddle >>> x = paddle.linalg.matrix_power(math.exp(1)*paddle.to_tensor([[1.,0],[0,1.]],dtype='float64'),n=2) >>> x Tensor(shape=[2, 2], dtype=float64, place=CUDAPlace(0), stop_gradient=True, [[7.38905565,...

two stage的部件分割评测以往大家都使用bbox score作为maskscore，现在大家都在考虑这个问题了；我之前和你在微信上讨论过这件事情；现在来看这件事情，你有好的idea吗？

你好，欢迎关注PASSL，我们后续会贴一些目标检测方面的应用案例～～
