I have Just re-implement coordconv using pytorch according to the paper: An Intriguing Failing of Convolutional Neural Networks and the CoordConv Solution 46.
In addition to the 2D convolution implementation mentioned in the paper, I also implemented the version of coordconv1d and coordconv3d using pytorch. If anyone needs it, please refer to my github repo: CoordConv 233.
Since I am not very familiar with the 3D convolution use, and I have not found a good data set for testing, if someone can help me prove the correctness of my recurrence, and improve the code, it would be better.
