AttributeError: module 's2cnn.utils' has no attribute 'cuda' about s2cnn

[zhixuanli]

In s2cnn/soft/s2_fft.py
I moved import s2cnn.utils.cuda as cuda_utils from line 42 to line 7, and the problem was solved.

But while training, the average loss keeps increase and the average acc keeps decrease.
I used the state.pkl from single gpu, maybe it's not suitable for multi-gpu to initialize with it.

I have no idea

@mariogeiger Apart from the ring like convolution kernel used here, is it possible for another form's kernel to get better performance?

[mariogeiger]

Ring like kernels giving better performance than near identity kernel is only an observation done with shrec17 experiment.
It might be that there is an even better kernel form for this dataset.
And I also think that the ideal kernel form depends on the dataset.

@mariogeiger Thank you for replying me. I just find that the ring like kernel will occupy too much RAM and may be a smaller kernel could be considered such as one quarter sphere.
