Temporarily freeze kornia at 0.4.0 to prevent breaking change

[ivanzvonkov]

kornia 0.4.1 released recently and it includes a breaking change to get_rotation_matrix2d

I've opened an Issue to hopefully address this soon: https://github.com/kornia/kornia/issues/742 but in the meantime, I suggest freezing kornia at 0.4.0 so that the random_rotate transform continues working as before

@ivanzvonkov thanks for this!

Very nice library guys and super well documented - we are very happy to see Kornia in here :)

Regarding the current issue - why not passing scale = torch.ones(b, 2) ? https://github.com/greentfrapp/lucent/blob/master/lucent/optvis/transform.py#L71

An alternative is to use kornia.rotate which doesn't take into account the scale as input.

Besides, I detected few other functionalities in your code that could be used directly with kornia. Let me list them:

• kornia.deg2rad https://github.com/greentfrapp/lucent/blob/master/lucent/optvis/transform.py#L69
• kornia.tensor_to_image https://github.com/greentfrapp/lucent/blob/master/lucent/optvis/render.py#L132
• kornia.normalize https://github.com/greentfrapp/lucent/blob/master/lucent/optvis/transform.py#L106

Last, what's the intuition or if you have any reference for _linear_decorrelate_color ? I believe with a proper API design would be great to have it in kornia.
