projection doesn't match observation

[dongzhuoer]

I add the following code after the 5th code cell of cryo-tutorial.ipynb

idx = np.random.randint(0, len(observations))
print(idx)
observation = observations[idx]
t = translations[idx] / D
R = rotmat3D_EA(rotation_representations[idx] / 180.0 * np.pi)            
pred_projection, _ = observation_model(protein, R, t)

utils.plot_fourier2real(observation.unsqueeze(0), name="real_transforms", save=False)
utils.plot_fourier2real(pred_projection, name="real_transforms", save=False)

However, it seems that the projection of ground truth density doesn't match corresponding particle image.
