Probable bug in SMPLH(X) class

[SergeiGorbatiuk]

Hello! Thanks for the great work you've done!
I have a question about the class of SMPLH (as well as SMPLX) model of package smplx from PyPi. There are following lines:

left_hand_pose = torch.einsum(
            'bi,ij->bj', [left_hand_pose, self.left_hand_components])
right_hand_pose = torch.einsum(
            'bi,ij->bj', [right_hand_pose, self.right_hand_components])

which as I understand provide axis-angle hand pose coefficients from PCA coefficients.
But when parameter use_pca set to False when initializing the model, it causes an obvious error when calling forward():

AttributeError: 'SMPLX' object has no attribute 'left_hand_components'

My question is: shouldn't there be an if-statement before this coefficient expansion?

@SergeyGorbatyuk171 you are right! I just add the if statement.
