Possible mistake in vanilla_vae 'loss_function' about pytorch-vae

[dvalenciar]

Agree, the negative sign was already added before, so it should not be there

[chengengliu]

Agree. Line#143 already has one negative sign.

[Maximusprime3]

this also happens in the mssim_vae.py
line#155
`

    kld_loss = torch.mean(-0.5 * torch.sum(1 + log_var - mu ** 2 - log_var.exp(), dim = 1), dim = 0) 

    loss = recons_loss + kld_weight * kld_loss
    return {'loss': loss, 'Reconstruction_Loss':recons_loss, 'KLD':-kld_loss}`
